Mac Mail - send unknown sender / not applicable

On one of the Mac Mail e-mail accounts stopped view my e-mails.

The displayed e-mail activity showed that emails have been received.

When I ran the account information on this mail box there were several

mails, labeled with the unknown sender and SUBJECT No..  These

were the emails that have been received but not displayed.

I know that these are valid e-mails since they appeared on my ipad.

Any idea what is the problem?  My other email accounts have

no problems - more when I deleted the emails from unknown senders

from the POP server with the option to delete the account info.

It appeared to correct the problems future emails.

Try to rebuild the mailbox.

Rebuild the mailbox

If this does not work, try re-indexing of mailboxes mailbox. This can take some time if you have a lot of mail.

Reindex messages        For El Capitan, try looking in V3.

  • Mac Mail can send but cannot receive mail.

    I have been in contact with my technical support of Verizon.  There is no problem to an end, but my Mac Mail account can send but not receive mail.  What happened three times during the month.  Each time than previous, Verizon has found a problem locally, for their purpose and in a few hours, it has been corrected.

    This time the problem was upstream at the highest tech people.  They told me that there must be a problem of registration with Mac Mail and I need to contact Apple.

    I tried physician connection without success.

    If someone knows a solution, I'll start here before you contact apple support.

    Mary Lou

    I've never had a problem with Verizon email on my Mac. In your case, Verizon has already said that they have been twice at fault. I'm guessing that this time is not different.

    I suggest you contact Apple support if Verizon has completed its investigation.

    original title: Windows e-mail viruses

    If you use Windows Mail in Vista, then go to tools | Options | Security and check the box warn if other applications send by mail like you.  I think, however, that your email address is being spoofed by another infected machine and send e-mails disguised coming from you.  There is not much you can do about it.

    Make sure that you machine is not infected by a virus scan (for example www.microsoft.com/security_essentials/) and search for malware (www.malwarebytes.org). But it may be that you or your machine that is responsible for sending spam that appears to come from your hand.

    Recently, there was a lighten strike that took all of Qwest service for more than 24 hours. Since then, I am unable to send that e-mail can receive but not send lucky. All my outgoing SMtP settings which are Centurytlink (Centuirytel) told me to use. When trying to send email back the server is not found.

    As said before, try STARTTLS instead of SSL/TLS for SMTP server.

  • Windows Mail can receive but not send up to exit application

    Hi and thanks for taking the time to read what I am in need of your help.

    I have a Toshiba P200, Vista Home Premium, Tiscali as my ISP, Norton Internet Security for AV and firewall and access my broadband via Ethernet to a Belkin ADSL router (and occasionally a Siemens router) and I am experiencing some strange events with Windows Mail.

    In short I can receive mail without any problems, but when I send the mail, remaining in the Outbox despite the option send immediately being checked, or by pressing the send/receive button. When I go out Windows Mail mail is sent immediately and is when I restart Windows Mail in the sent messages folder.

    So why I think there is a problem with the laptop. Well, I'm lucky to have a friend who has a non-Toshiba laptop, where all of the above can be replicated. Guess what, Windows Mail sends the message exactly as it should (on my account and on my network, through my router and the ISP, Tiscali etc.), so I conclude that the only difference is that my laptop is a P200.

    I called Tiscali, which confirmed that all my mail settings were OK, POP, SMTP etc, which I expect (because they work on the laptop from my friend), and they advised to contact Microsoft, I did, and since the P200 has pre-installed Vista they say that I need to contact Toshiba, and here I am.
    My P200 has been restored to factory settings, and I tried to get this working without Norton IS and no firewall (Vista and router) but no luck.

    Any ideas would be very appreciated and if I find through other means, I'll post back with the result. If the answer is already out there, please apologize for being too stupid to locate and beg your patience.

    Thank you very much.

    Hello

    It is typical for support persons. All of them are trying to refer clients and through them. In my opinion Microsoft s reaction is strange to me. They designed the operating system and they should be responsible for the feature.

    I have the Satellite A200 and Satellite P200D and I use Windows Mail on two of them successfully. My laptop is connected to the WIFI router and router directly to the phone line. To be honest, I have configured Windows Mail as you and all of the work are made in a few minutes.

    It is not easy to tell where the problem may be, but I think that there is a problem with some settings of your laptop. Some of them block it somehow. To compare your, with friends laptop is also not the best because it can have completely different OS settings (antivir application, the settings of the firewall).

    Try turning off all the features that can block Windows hotmail to see if there is some difference.

  • I have a question regarding windows mail. I was send and receive mail with no problems until last Thursday. I can still receive mail, but I can not send.

    / * moved from answers Feedback * /.
     
    I have a question regarding windows mail. I was send and receive mail with no problems until last Thursday. I can still receive mail, but I can not send. My email is with bellsouth.net and comes in my computer through windows Messaging.  I spent an hour and a half on the phone with bellsouth, and they say that the problem is with my windows mail.  I tried to use a restore date, and that did not help either. I will post a copy of this message, as I keep getting.  Your server suddenly put an end to the connection. The possible causes for this include server problems, network problems, or a long period of inactivity. Object 't', counts: 'mail.bellsouth.net', server: 'mail.bellsouth.net', Protocol: SMTP, Port: 25, secure (SSL): no, error number: 0x800CCC0F thanks for any help.

    Sometimes, WinMail settings get screwed up and you must remove the account and then add it back back.  Make sure first that the antivirus software not interfere (see www.oehelp.com/OETips.aspx#3).   Delete your account completely, then close WinMail.  Then compact and repair the database of WinMail (see www.oehelp.com/WMUtil/).  Add your account to mail back once again, and then make sure you have the correct settings under Tools | Accounts | Mail | Properties | Servers and | Advanced to what AT & T Specifies to WinMail (or OE).  Then see if it works.

  • What happens in Windows Mail? I can not send attachments with any type of graph.

    Unreal

    What happens in Windows Mail? I can not send attachments with any type of graph. People receiving my email with attachments receive between 60 and 70 copies. I called my provider, my safety, send the computer for a week for a Tech and no one can answer this problem for me. If I don't get this problem resolved I will never use Microsofts again e-mail programs.

    Tools | Accounts | Mail | Properties | Advanced. Uncheck the box: "Break apart messages...". ».
    If this isn't the cause, try to compact and repair the database.

    Windows mail send any ip ok no error. Ox 800ccc79 cylindrical invalid not port 25 secure SSL error 550 Server

    You try to send a file larger than 20 MB.  Try to reduce the size of the attachment of zipping it or go to tools | Accounts | Mail | Properties | Advanced and select the option to break messages apart large.  However, many recipients servers will not accept messages exceeds 10 megabytes, then you could try to send via another method.  BTW, if you attach a file, it must be encoded to be sent by e-mail, and this coding adds about 30-50% the size.

  • Windows live mail send error "the server does not support an SSL connection. Server error 250.

    Original title: Windows live mail error send

    Cannot send mail to Windows Live Mail.  Error message... The server does not support an SSL connection. Server error 250. Server - * address email is removed from the privacy *. Windows Live Mail error ID - 0x800CCC7D. SMTP Protocol.  Port 25.

    It's better, thank you. This message is not from the BT Server; It comes from your Avast antivirus which is intercepting your mail. You would be well advised to turn off the Avast Mail shield; It does not add any additional security if you don't by attention elsewhere, and can cause problems.

    I see that it is the record of mail in bulk that because of the problems in this case. Connect to the Web e-mail account and clear the items junk and deleted records.

    BT is recommended to use SSL, but your original question indicated that SSL was not taken in charge for SMTP on port 25. I think we'd better go on all your settings. Recommendations of BT are on this page: BT email: what are the settings for outgoing and incoming mail servers?, but they only work if you disable Avast scanning mail.

    Right-click on the account name in the folders pane, and then select Properties.

    • Under the servers tab, make sure that my server requires authentication is selected.
      Select connect with authentication in clear text.
    • On the Advanced tab, select this server requires a secure connection (SSL) for both servers.
      Make sure that the incoming (IMAP) port is 993 and port for outgoing (SMTP) is 465.

    When you've made all these changes, close Windows Live mail and wait five minutes for the program do its cleaning and save the modified settings. Then, restart the computer and make sure that the Mail of Avast shield is always off.

    Launch Windows Live Mail, then dial a new test message and send it to yourself. Post a new message in your response.

  • Mac Mail did not request a new password after changing the outside

    Hello world

    I recently changed my password of gmail on their web site after "suspicious activity" had been detected. But Mac Mail does not work. Still able to send and receive emails and it asks me to enter a new password.

    How is that possible? Any ideas?

    If you have enabled the validation in 2 steps, you generated a password specific to the application in your Google Mail account and it is entered instead of the login password you use on the Web site.
