Unable to send emails, SMPT can not connect to the server

I use the latest version of the EL CAPTAIN 10.11.04, just updated software, and I can not send my emails is to show only SMTP error can not connect to the server.

I can receive emails, but cannot send emails. I deleted the account and reinstalled it once again changed the SMTP Port 25, 465, 993 trying all of them.

Please advice, or guide me what I am doing wrong, or what I can do to fix this error.

Please take each of the following steps that you have already tried, tests after each of them. Back up all data before making any changes.

Step 1

In the Mail menu bar, select

▹ Connection Doctor window

In the window that opens, double-click on behalf of SMTP (outgoing mail) problem. it. another window opens, displaying the list of all outgoing mail accounts. Choose the one that you clicked.

Select the Advanced tab in the settings for the account and check the box marked

Automatically detect and maintain the account settings

If it is not already done.

If there is more than one account of the problem, repeat. Close the window and save the changes.

Step 2

Open again the list of SMTP servers. Note the problem server settings, then click the sign button less to delete and confirm. Click on the sign more and recreate the account with the same settings.

If you use Gmail, remove the account completely in the preferences panel accounts Internet and re-create it. The option "detect and maintain" must be selected in advanced settings for the incoming mail account.

Messages will be again synchronized with the server automatically. Which can last for hours if the mailboxes are very large.

Step 3

Quit Mail runs. Launch the Keychain Access app and enter the name of the server of mail out in the search box. For example, if you use Gmail, enter

SMTP.gmail.com

Make a note of the password, and then delete the keychain items. The next time Mail connects to the server, it will prompt for the password. Enter and save the password in the keychain.

Step 4

If you use Gmail, sign in to your account on the site, and in the account settings, click the "Sign-in and security." There should be an option somewhere on the page to "allow applications that are less safe." Enable this option and save the change. Note: I don't use Gmail and I have not tested this solution myself. If it does not, either make you on Google user forums for help, stop trying to use Gmail with the e-mail, or just stop using Gmail altogether (strongly recommended).

The mail server can use a form low, obsolete encryption for secure communications with customers. Recent versions of Mac OS X has changed the behavior of Mail and other applications so that they no longer tolerate low security.

Log on to the e-mail account on the website and see if there is a security setting, you can change. I can't be more specific. Refer to the documentation of the service provider.

If there is no adjustment, convince the upgrade of server securityserver administrator. He or she must do it anyway. Low security affects all customers, not only Mac users.

Otherwise, you have all the right options to continue to use Mail with the service. You can disable SSL in the Advanced account settings, but that is very dangerous and may not work at all.

You might be able to get a more flexible mail client, such as "Thunderbird", to accept the low security, or perhaps you can access the account via webmail.

Ideally, you should switch to a provider of postal services better. You would not have this problem with a well-run service. The risk of weak SSL are known for a long time, and to competent server administrators have already taken the simple steps are sufficient to avoid these risks.

  • BlackBerry smartphones can not CONNECT to THE SERVER

    Hello need help. My Blackberry Curve 8520 (OS 5.0.0.1036) does not connect to the server. It shows my network (Vodafone) and gets a strong signal; makes and receives calls; connect wifi; but it is also completely static. After the first Setup email screen I get: your device has a connection to the server problm.  (I think it means the Blackberry server?)  So I can not connect any email.  Very well in my other near-identical Curve 8520 Sim Card work.  How can I do please?  Y at - it a reset or software update is complete I can undertake? Thank you, Michael

    I can help you with the it policy... lack of procedure for access to the BES server, this (and only this) cleanse a BB to an it policy:

    • Article ID: KB31291 How to reset a BlackBerry smartphone to factory using BlackBerry Desktop Software Settings

    If you do a backup/restore, don't do this basically... rather, backup/restore only the databases specific you need (for example, calendar, contacts, messages, etc.) and more precisely to avoid data bases having something to with COMPUTER policy, business, etc.. If you restore those, the it policy will be conscientiously restored to the device, and you will be right where you are now.

    As for a BES Server trying to reach out... There is nothing that I can offer you. Your best bet is to talk to your provider and make sure you have no BES-level service enabled on your account of them. Who should (note 'should'... is there no guarantees) prevent a BES server to reach out and the reactivation of your device.

    Good luck!

  • can not connect with the server.

    I can't connect to the internet. WI - FI connected and at full power. This just happened and it's never happened before.

    Hi, it seems that there is a problem with the connection between your router and the dsl modem. Make sure the pin of the Ethernet cable is plugged correctly in any LAN port available on DSL Modem and on the WLAN port in the Wifi router.

    Go to 192.168.0.1, run the installation/quick installation program from this interface and make sure that you preferred DNS address type 192.168.1.1 or default of the DSL Modem ip address if you know it's different.

    It is always a good thing to restart both the DSL/ADSL Modem wireless router periodically to refresh the system and you will face less problems like the one you face now. If both modems are enabled for quiet a long time, it can either be hanged or perhaps become hot to damaged. So reboot them once quiet often when not on duty.

  • DSS can not connect to the server

    When you try to start the Configuration utility of the software of digital transmission (DSS) in version 5.01.03, I get the following popup error message:

    HP. DSS. App.ConfigurationUtility.View

    Configuration utility stops because the connection to the DSS Service expired.  Please check the status of service DSS.  Restart DSS service manually if necessary.

    The service is running and restart service does not help.

    Any suggestions on who to fix this?

    P.S. This thread has been moved printing and digital imaging > Digital Sender software. Forum Moderator - HP

    The problem seems to be the .NET Framework 4.5 which is installed as part of installing DSS.  After that which is patched DSS stops working.

    We have confirmed this by uninstalling .net Framework 4.5 and DSS, reinstall and patch .NET Framework 4.5.  After reinstallation of reworked DSS, but after you have applied the patches of .NET Framework 4.5, DSS has stopped working again.

  • "iPhone is disabled, connect to iTunes" AND "iTunes can not connect to the iPhone because it is locked with a password" error message on the phone and the computer! Help!

    So I recently had my password wrong too many times and my iPhone 4S locked out telling me "iPhone is disabled; Connect to iTunes'. And so I connected to iTunes and decided to restore my phone. I finished the process of restoration of the configuration of my phone, but ultimately, it was not even let me in the phone! Once AGAIN he said "iPhone is disabled; " Connect " to iTunes '. However, this time, this message appeared just when I turned on my phone with a black background. I didn't scan the screen for the error message is displayed (and there was no time to be shown). When I tried to connect to iTunes again as he asked, now it says "iTunes can not connect to the iPhone because it is locked with a password".

    So now, he said "iPhone is disabled; ' Connect to iTunes' on my iPhone 4S and ''iTunes can't connect to the iPhone because it is locked with a password ' on my computer. WHAT should I do?

    As described in step 2 of "Erase your device with iTunes" in this article, you will need to use the Recovery Mode.

    Recovery mode is described in this article as well.  You may try to go into recovery mode more than once to succeed.

    If you have forgotten the password for your iPhone, iPad or iPod touch, or your device is disabled - Apple supports

    Since the update to El capitan OSX 10.11.4 on my Macbook Pro (2012) I can not connect to the app store - ideas? Im not geek so please be gentle!

    Try restarting mode without failure. To restart in safe mode, restart the computer and press on and hold down the SHIFT key until the Apple icon appears. The computer starts more slowly than usual because the disk utility checks the drive. After getting on the desktop launch the App store and try to connect. Successful or not, once you're done, restart normally to exit safe mode.

  • After cleanind my registry with Wise Registry Cleaner, I can not connect to the internet.

    Network connection problem

    Hi all

    After cleanind my registry with Wise Registry Cleaner, I can not connect to the internet. Network LAN and wireless do not work. Windows 7 has diagnosed the problem and says the following:

    There might be a problem with the driver for the wireless network connection card

    Windows could not automatically bind the pile of IP protocol for the network card.

    There might be a problem with the driver for the connection to the Local network map

    Windows could not automatically bind the Protocol IP on the network card stack.

    Similar to Wireless adapt. The problem is probably not the antivirus program, since I have only deinstaled and the problem persists. I've also uninstalled and reinstalled the drivers, but no solution again. I can't do a system restore point before cleaning the registry, because Windows could not find a file that is needed for the restore. I restored again since before saved registry cleaning but no help.

    Any other ideas please. This really seems teribble :(

    Thank you
