Mail has stopped sending or receiving. I have restarted a few times but nothing.

    Have a look at all Mail preferences and see if they appear reasonable.

    Open the Connection Doctor and the Activity Monitor from the menu and see what exactly is going on...

    I am connected to the internet and am able to receive mail via my comcast.net account. THe comcast SMTP is connected. The Comcast POP, however, is spinning eternally. I have checked the mail preferences and everything looks normal.

    What does connection doctor show when you access that account?

  • kathlenry Level 1 Level 1 (0 points)

    It shows the POP is not connected. THe dot is red. When I double click on that, it tries to connect and the little gyroscope thing spins on and on.

    What does it say in the third column (under Details)?

    Is this report from the Connection Doctor in Mail in the third column under details [Window -> Connection Doctor] -- usually it tells you whats wrong in plain English?

  • kathlenry Level 1 Level 1 (0 points)

    It says verify that username and password are correct. They are and I believe I have verified. (Thank you for helping me!)

  • pberk Level 2 Level 2 (285 points)

    Sometimes those files get corrupted.  Take out the information re username and password from the account (in Mail Preferences -> Account>.  close that window so it saves... then reopen it and re-enter the username and password information.  Lots of times that will fix it.  [Or you can just delete he account and resset itup (before you do that, move anything sitting inthe inboxfor that account into a folder in Mail)

  • kathlenry Level 1 Level 1 (0 points)

    IT worked. thank you soooooooooo much. I had to delete the account and re-establish. Whew.

  • pberk Level 2 Level 2 (285 points)

    You're welcome!


    (you should make this thread as "solved" so others can find out how to fix the same issue (it will show up in a search of the forums as an issue with a solution)

    It shows trying to connect to server. Since I also have a Macmini for many years which is connected to the same server with no flaws - the server settings are correct. Checked a zillion times already.

  • Butterfly*8 Level 1 Level 1 (0 points)

    I am trying to use your advice to remove username and password and save and close the window, but I am given the message that "username cannot be empty."


    I am using Mountain Lion on a new 27" iMac that I just got set up in March of this year 2013.  All of a sudden in the middle of the day 12 days ago Apple's Mail program stopped working.  At first the Connection Doctor showed red for both send and receive, and now it will send but not receive for many, many days.  I downloaded Thunderbird to test this because Comcast was telling me nothing was wrong.  Thunderbird sends and receives on my computer.  At first it would only send but now it does both.  Who knows why - I didn't change anything.


    The only thing it receives is copies of messages that I have sent from Gmail that I have set up that way, so Gmail's server sends it and it is accepted.  I can see my email on Comcast's Xfinity when I log in to that, but that is awful, and difficult to use.  On Xfinity if you delete a message by mistake (I pressed backspace, I think), there is no way to get the message to move back to inbox or to use it from there to reply and send with the message in that position.


    I SO was hoping that by deleting my username and password I could fix this.  Any other way to help?  I have several years of mail in my inbox.
