I have a account which worked fine for years, including on my iMac until recently. I started having problems after I upgraded my iMac to Lion, then everything went downhill after I had to change my password a couple of weeks ago:


This is a POP account but Mac Mail keeps showing the incoming mail server as IMAP. I have removed and added the account over and over again. The mail program won't let me configure the account manually. As soon as I give my email address and password it goeas ahead, looks for the account, finds it and configures it. Then it downloads the inbox (very slowly as in an imap account), but won't let me send any emails. I keep getting the error message "Yahoo outgoing mail server rejected your password". Subsequently, the contents of my inbox disappear too.


I have checked all the incoming and outgoing mail server names, ports, etc. at the AT&T site and manually entered them in the account settings to no avail.


I tried to ask AT&T and they ended up telling me I would have to sign up for paid support for Mac mail as they only supported Outlook for free.


Finally, note that this mail account works fine with my iPhone, iPad as well as my Macbook Pro (running OS X Snow Leopard)


Any insights?

    To get the choice of setting up a POP or IMAP account, on the Add Account sheet either enter an invalid email address (you can correct it later) or control click the Continue button (or maybe option click, I never remember which is which).


    As for the password problem I may have an answer for that but only if you are using AT&T U-verse.  Are you?

    Does AT&T DSL use the yahoo mail servers?

    Yes, I know.  But yahoo still manages the servers.  I have U-verse but use those two mail servers too.


    Ok, here's the possible problem with the password.  This is based on my recent password problem I had just last week. 


    The history here is I have had U-verse for over 4 years with no mail password problems.  And when I started having authentication problems I tried another machine and even my neighbor's machine and concluded it wasn't anything on my side.  It had to be the mail server side that was having the problem.


    When this started I was experimenting with mail utility where I explicitly needed to enter the mail password.  Occasionally I would make a typing error and of course the password wasn't accepted.  It was after doing this a few times I began having the authentication problems in my mail client.


    After talking to AT&T tier 2 and them verifying for them self that it wasn't accepting my password (even though I could log into the AT&T site with it) they figured out how to fix it.  Of course I asked for the info too so if this ever happens again I would know how to fix it if it occurred in the future.


    It turns out that if you  have enough incorrect logins (not sure how many) the yahoo mail servers, in their infinite wisdom, think something illegal is going on (intrusion attempt), and disable the account.


    The AT&T tier 2 guy did this for me but he said this is how you reenable the account.  Log into  You will be presented with an authentication dialog (AT&T described it as something like a capcha).  Once you get accepted the account is reenabled.


    I hope this info applies to you.


    Good luck.

    Exact same servers and same ports U-verse uses.  I'm not really surprised at that.  DSL or VDSL (U-verse) all end up at the same place.

    You guys rock! After spending 100 minutes on the phone with three people at AT&T tech support, I was told "Ummm, maybe you should go to an Apple Store?"  One search on discussions and va-blamm! Problem solved.  Good going!

    Apple needs to update their automatic settings to what AT&T requires, the POP account using and

    Yes, this sign in at Yahoo mail over the internet does get mac mail to connect but aflter your system goes to sleep and wakes up then the connection was lost.  something to do with sleeping breaking the connection and not reconnecting at wake up.

    Yes, this solved my problem, too.  The correct key combination is Option + Continue. You then have to enter and manually. Port 995 is selected for the POP server. I never saw a choice to select Port 465 for the SMTP server, but the account works correctly.  It also solved the problem I was having with deleted mail reappearing.
