Unable to send email messages

I have been unable to send email messages for two weeks. Error messages are "cannot connect to SMTP mail server. Contact Internet Service Provider" 

Please see http://customer.xfinity.com/help-and-support/internet/email-client-programs-with-xfinity-email/. What email program or app are you using?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
    Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.

    You have to request you Network team to add the ip address of the machine where you have installed content server to your Exchange Server.
    Let me know if it works.

  • IPhone 6 is unable to send email because the sender address was rejected by the server

    When I try to send emails from my Microsoft Outlook for Mac, I get a message that says "Unable to Send Email.  A copy has been placed in your Outbox.  The sender address was rejected by the server."  I've checked all the settings (it is a POP account).  I've deleted and re-installed.  Any suggestions??

  • Tired of getting "Protocol layer was unable to send a message" - Update to 10.2

    I'm extremly glad to report that RIM has finally resolved  the ongoing "protocol layer" failure to send email from certain types of accounts.
    A while back they post this not working solution:
    KB33736 "Protocol layer was unable to send a message" when replying to an email on the BlackBerry 10 smartphone
    Resolution: Upgrade to BlackBerry 10 OS version 10.1.0.1465 or higher. Contact the wireless provider to confirm availability.  
    10.1.0.1465 or higher FAIL
    But 10.2 WORKS - Woohoo

    there are two articles from the public knowledge base about that error, for very different reasons.
    KB33736 "Protocol layer was unable to send a message" when replying to an email on the BlackBerry 10 smartphone
    KB34009 "MessageStatus: Protocol layer was unable to send a message" is displayed when sending email with an attachment on a BlackBerry 10 smartphone

    Since yesterday I'm unable to send emails on any of my Apple devices. The revert is that I have exceeded the maximum number of emails per day, but I had only sent out 24 with no bulk emailing -  (much less than 1000 recipients as per the website) and I'm STILL not able to send emails.

    Hi.
    You have an option set that is incorrect I'm afraid.
    In the Account properties, have a look at the Advanced tab, and make sure that the first option (This server requires a secure conection) is not ticked.
