Re: [Dovecot] Dovecot and Outlook Express "plaintext authentication not allowed..."

On Tue, 17 Apr 2012 13:41:20 -0700 (PDT) D Chen articulated:

Per your suggestion, in Outlook Express I changed to use SSL on port 993 for IMAP, and port 465 for SMTP, the creation of the new account succeeded without error!  However, when tried to send to my yahoo mail or gmail acct,  got the following error: (apparently failed to send!)

"The message could not be sent because one of the recipients was rejected by the server.  The rejected email address was 'dchenusa@yahoo.com.'  Subject: 'test out to yahoo mail' Account:'dchen192.168.20.100' Server: 192.168.20.100 Protocol: SMTP, server response: 554 5.7.1 : client host rejected access denied, port: 465, Secured [SSL]: Yes, server Error: 554, Error number: 0x800CCC79"

PS. in the same client PC, using Thunderbird client, IMAP and SMTP configured with either with SSL or without SSL, both outgoing mails were sent successfully!

Any thought?

Well, my first thought is that you should lost the tendency to "Top Post".

Second, why are you screwing around with the SMTP settings? Dovecot could not care less about them.

Third, Outlook Express has been abandoned years ago. Why are you still using it? If you really need it, try Windows Live Essentials http://windows.microsoft.com/en-US/windows-live/essentials-other-programs. I know users who have it working with Dovecot just fine.
