• How to change the smtp Protocol. element of the outgoing mail server

  When adding to an existing e-mail account, it is not possible to change the part "smtp." from the address of the outgoing mail server.
  My smtp server name is "mailout.easymail.ca".
  How can I configure this?

  The wizard does not any part of the server names. I think you're confusing a label that simply States the type of server with the actual server name text entry (or more accurately, the address).

• PIX 515E external SMTP and POP access DMZ

  Hi all

  I need help to solve the problem I am facing with the configuration.

  config: PIX515E Ver 6.3 (1), with 6 interfaces outside the interface is connected to the Internet router and assigned public IP. Access to the Internet is configured for users connected inside Interface only using the command Nat & Global (Global off-1 Interface). I want to activate the access to electronic mail (SMTP & POP3) host couple in one of the demilitarized zone.

  1 NAT configured on the interface & access list applied. If I allowed SMTP & POP only I even don't get a kick on the access list. If I have IP enable any of these hosts, I can surf the net, E-mail etc. After that when I restict to SMTP & POP only, it works for a while, after some time, I don't see any future success to the access list.

  What could the case of such behavior, I missing something...?, I'm confused.

  Thanks in advance.

  Best regards

  Ensure that you allow DNS from these hosts too (UDP/53), as they're going to do queries DNS for the remote host IP address and the domain MX record before they can establish a connection to the mail host relevant external.

  If you allow all IP then they will be able to make the DNS query, then perform the connection SMTP/POP, and they will be cached DNS queries for awhile that's why it works for a while after the removal of the ACL. Once the DNS cache expires in these hosts, they must make another DNS query causing crashes so that you don't have him through the ACL permits.

• Pix 501 problem, I can not receive smtp messages

  Currently, I can send messages but cannot receive the mail from the Internet, if I remove the Pix and connect directly to the Modem/router then I can SMTP on port 25 and SMTP mail works fine both in & out.

  All what we want this Pix to allow at present is:

  (a) access to Internet to all clients on the network internal

  (b) allow the customers to pop mail web e-mail accounts

  (c) we want to use Exchange & Outlook and accommodate our own email via the SMTP Protocol

  Please find attached two documents: -.

  1. a current edited config of my Pix 501 running

  2. a PowerPoint of my network diagram.

  I appreciate a lot of help.

  Vinny.

  I finally found the problem.

  On the ADSL router, you have configured the same 192.168.0.0/24 network you use behind the post office

  Server. This configuration will not work because it leads to a duplicate IP address range and you have routing

  problems.

  Change the configuration to another range of IP between the ADSL router and PIX firewall and everthing will be

  work.

  Note the address unique public IP that is configured, received is on the router Netgear ADSL uses all other interfaces

  public IP addresses.

  Recovery of the networks and the IPs:

  80.x.y.z/255.255.255.x = Netgear outside intellectual property

  192.168.2.0/255.255.255.0 = network between the internal Netgear and the PIX outside interface

  192.168.1.0/255.255.255.0 = network between the PIX inside and the external interface of the mail server

  192.168.0.0/255.255.255.0 = network between the internal interface of mail server and mail clients.

  Use 192.168.2.0 255.255.255.0 for this network, and then set it 192.168.2.1 for your ADSL router inside

  interface, use a static IP 192.168.2.2 255.255.255.0 on the PIX firewall outside interface.

  ADSL installation:

  You can choose on the Netgear between all public traffic of the 80.x.y.z IP to 192.168.2.2 transmission which is NAT or

  You can transfer to forward the http, pop3 and smtp, didn't really matter, it's just important that you NAT or PAT it

  for the PIX firewall.

  PIX installation example:

  All traffic received on the PIX outside interface for http, pop3 and smtp is then transmitted by 192.168.2.2 to mail

  the server 192.168.1.2 external IP address.

  outdoor IP 192.168.2.2 address 255.255.255.0

  IP address inside 192.168.1.1 255.255.255.0

  acl_out list access permit tcp any host 192.168.2.2 eq http

  acl_out list access permit tcp any host 192.168.2.2 pop eq

  acl_out list access permit tcp any host 192.168.2.2 eq smtp

  Access-group acl_out in interface outside

  static (inside, outside) tcp 192.168.2.2 80 192.168.1.2 80 netmask 255.255.255.255 0 0

  static (inside, outside) tcp 192.168.2.2 110 192.168.1.2 110 netmask 255.255.255.255 0 0

  static (inside, outside) tcp 192.168.2.2 25 192.168.1.2 25 netmask 255.255.255.255 0 0

  Global 1 interface (outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0

  Route outside 0.0.0.0 0.0.0.0 192.168.2.1

  Installation of mail server:

  The mail server has a default route to the PIX firewall.

  Default gateway on the mail server = 192.168.1.1

  Do you have NAt or PAT on the mail server internal clients to the Internet in the direction of the PIX? If not, you need to add another road on the PIX, so know the PIX the 192.168.0.0/24 network is behind the e-mail server, as this unit is the routing for this network.

  Add a route on the PIX inside interface:

  Route inside 192.168.0.0 255.255.255.0 192.168.1.2

  E-mail clients:

  All mail clients have the internal IP address of mail as default gateway server.

  Default gateway = 192.168.0.3

  This configuration will work 100%

  Sorry if I you confused.

• Confused about the new iPhone to load

  It seems that online, there are many variations on how to charge an iPhone the first times, we don't know what to believe.

  Historically, I charge my iPhone for a day the first time that I get it or after I got a refurb from Apple. My battery life has always been fantastic, representatives of engineering apply even told to say.

  This time, I couldn't wait to load the device as I normally would. I connected my iPhone to my PC, did a restore of backup and wait for the iPhone to be able to load completely (about 30 minutes).

  Given that I had a lot of things happens, I didn't have the opportunity to "condition" of the battery, charge of the day to the next, or as some reports say that I have to load it only via the provided OEM charger (not PC). Some say that your battery die completely and then get away after the phone two hours before recharging.

  All these 'new' information is downright confusing. And yet, I see Apple suggesting as a result a large part of these 'tips '.

  Any thoughts on pricing?

  There is no requirement to 'manage' load.

  Charge at any time, for any period of time.

  You can use the phone while charging.

  Don't deplete the battery at a low level.

  Another that these steps, no more measures need to be taken.

• Problem with SMTP servers that disappear

  I've recently updated to the official version of Sierra.

  Since then, I can't send mail more.

  I have a special setup in Apple Mail: I config a manual counting that iCloud as IMAP for receiving server and Gmail as SMTP server to send. That allows me to have sort of a double synchronization with iCloud and Gmail.

  It was working perfectly until that date, but after Sierra upgrade it keeps losing my SMTP server config.

  After some instructions on mail and Sierra problems (in this thread: Re: IMAP e-mail accounts went into Mail after upgrade of Sierra), I have built my mail again, created new account, but the problem remains.

  What happens is that it continues to lose my SMTP server. I re-entered 20 times or more, save, but she mysteriously disappears. I go to Mail > Preferences > accounts, select my manual counting and this is what I see under "server settings":

  

  Password is missing. Username loses the game ' @gmail.com ' email address and authentication is set to None.

  If I'm in all the fields correctly, switch tabs, back: it's all gone!

  I tried to remove the smtp server and create a new one, but the same happens.

  All faced a similar problem? Do you have an idea how solve it?

  Thanks a lot for help.

• I'm able to add my mail at the post office, but it says error IMAP and SMTP

  I am able to add my accounts (I have a yahoo and gmail) but they are not connected. Connection doctor says its an error with IMAP and SMTP. I also have trouble with the addition of outlook. I also installed Outlook 2016 and yahoo and gmail also have problems connecting through the IMAP and SMTP.

  Can someone give me a suggestions to solve this problem?

  First of all, make sure you have an active Internet connection by opening a web browser and try to use your accounts through their webmail interface.

  If it works, so be sure that you are on a reliable WiFi network (for example, at home) which does not block e-mail protocols.

  And finally, if you have any security antivirus or other software installed on your Mac, then remove it completely according to the manufacturer's instructions, restart and then try to add your accounts again.

• Unable to connect to an smtp server

  My OS is ubuntu LTS 14.10, I use Thunderbird version 38.4.0.
  I have 2 accounts, a gmail account and an e-mail office365 account.
  Until yesterday, I could send and receive emails on both accounts, however now it fails with the following error:

  The message send failed.
  The message cannot be sent because the connection to the server failed outgoing (SMTP) smtp.googlemail.com . The server is may be unavailable or refuses the outgoing (SMTP) server connections. Check that your outgoing (SMTP) server settings are correct and try again.

  (Or a similar message when connecting to the server smtp office 365.)

  I restarted the computer, confirmed the address of server, reset passwords, confirmed that I can ping the servers.

  Any help would be greatly appreciated.

  Thank you

  Chris

  The parameters of your server for Gmail seem good. I'm not really familiar with Office365, but they are probably ok as well.

  Are there external firewall or proxy, you have to go?
  You have all this computer's Internet access?

  What is suspicious, that the two accounts are not at the same time. So my best guess is that the cause is rather external and not Thunderbird.

• Gmail SMTP Incorrect salutation 10060

  I have been using Thunderbird to download my gmail for years, without any problem. I am currently on 38.4.0. In recent days, when you try to send an e-mail, I started having:
  An error occurred sending mail: the mail server has sent a wrong message: unable to connect to the server of SMTP 2607:f8b0:400 d: c08::6 c (2607:f8b0:400 d: c08::6 c: 587), connect error 10060.

  I changed the settings, so I wonder if gmail or Thunderbird changed (because it update?). I have my settings in the value of Thunderbird
  SMTP.gmail.com
  port 587
  STARTTLS
  Authentication: Normal password
  Username: [email protected]

  Thanks in advance for any help.

  Good server settings appear.
  Is there a personal firewall or a proxy server that may prevent the Thunderbird to connect to the server?

  Note that when you connect using OAuth2 the first time, you are prompted to enter your Gmail password in a browser window. It is your actual Gmail password, not any specific application password.
  After that, you are asked to leave Thunderbird to access Gmail.

• How to determine the outgoing (SMTP) server settings?

  ErrorMessage:
  The message send failed.
  The message could not be sent to the help of Outgoing server (SMTP) smtp.uniq.edu.ht for an unknown reason. Check that your outgoing (SMTP) server settings are correct and try again...

  How to do this? The parameters are defined automatically. Maybe Thunderbird should check its database of the email provider.

  It would appear that the outgoing serer must be
  Outgoing mail server: (SSL) box810.bluehost.com (server requires authentication) port 465

  THEN right-click on the account in the list and select settings
  Open the entry in the list of accounts for the outgoing (SMTP) Server
  Select your outbound service, and then click on edit.
  Update of the parameters specified by your provider.

• I would like to know how to prevent messages sent to be registered on the SMTP server

  Currently, my Thunderbird client saves a copy of all messages sent to the folder "sent", as expected. All sent messages are also stored on the Server SMTP (G-Mail in this case). To avoid having to delete them manually, I want to warn the outgoing message to be stored on the SMTP server in the first place. Currently, my account of Thunderbird for Copies and folders settings has a check mark next to the option 'Other' with a destination of the folder option sent in Thunderbird. I don't see any other parameters that could control how sent SMTP mail server handles. I use the POP service only with the G-Mail Server. What settings should be in place to prevent messages accumulate in the folder "sent" on the SMTP server account?

  I think I can now answer my own question! The question turns out to be a g-mail not delivered not a factor controlled by Thunderbird.

  Apparently g-mail can automatically a copy of all mail sent by SMTP service one account. It's a "feature" that cannot be disabled! A workaround seems to be to set up a filter in g-mail account settings for all mail with an address corresponding to your own email address and send the message to the trash folder. Items in the Recycle Bin are automatically deleted after 30 days. Google prevents the rule 30 days being modified by measure of security, but at least trashed messages for irrevocably removed in a month.
