Mac Mail- Inbound POP login fails; SMTP login works

Question

Recently I started to have problems with one of my email IDs.  Mac Mail shows it offline (tilde). I have four IDs all with the same settings but one fails when it attempts POP3 login to retrieve messages.  This ID CAN log in and SEND messages via SMTP.  I ran Connection Doctor against a working ID and the failing one. See difference below:Good ID                                                                      Failing ID&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;                                               &#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;INITIATING CONNECTION                                         &lt;sameREAD / +OK POP3 READY                                         &lt;sameWROTE /  CAPA                                                          &lt;sameREAD / +OK / TOP USER SASL LOGIN PLAIN .        &lt;sameWROTE / AUTH PLAIN                                                &lt;same              READ / +                                                                      &lt;sameWROTE / ******************************************               WROTE / *                       [mail wrote 1 star only!]READ / +OK SERVER READY                                     READ / -ERR INVALID COMMANDWROTE / STAT                                                             WROTE / AUTH LOGINREAD / +OK 498 167672785                                       READ / -ERR  ..more exchanges here...                                              WROTE / QUIT               [POP3 Login has failed]I&#x27;m guessing the long string of stars would be the login userID and password, and Mail doesn&#x27;t send it for the failing ID.  I can logon directly to the server with a browser so pswd is good.  SMTP login works for all IDs.   When you look at mailbox/account parameters they are all identical.  Whatsup??

Call off the dogs!!Problem went away after responding to logon fail message (which I&#x27;ve done in the past).Mail also had blanked out the password in Mail &gt; Accounts &gt; userID.  Once that was filled in it worked. Maybe the recovery is to blank out the password, then Get Mail, and respond to the two error messages.

Call off the dogs!It is working. I got the normal Login Fail message and replied to it with the correct password.  Then Mail put up a window for this userID showing the  password had been blanked out - I didn&#x27;t do it.maybe the recovery for this is to deliberately go to Mail &gt; Accounts &gt; userID and blank out the password.  The do Get Mail and respond to the two error messages.  Who knows.
