I am using a Fedora 37 server with sendmail/dovecot I have set thunderbird to use authentication (STARTTLS) IMAP works fine... mailboxes all show up and are current When I attempt to send an email I get a message that Authentication is required. I check my server logs and this is what I see:

55696 >>> 530 5.7.0 Authentication required 55696 <<< [EOF] 55696 >>> 421 4.4.1 domainname.com Lost input channel from sender.gateway.com [xx.xx.xx.xx]

There does not seem to be any attempt to authenticate. It just drops the connection.

Any ideas out there?

Additional info:

On the server, the maillog shows:

STARTTLS=server, relay=my.server.com [xx.xx.xx.xx], version=TLSv1.3, verify=NOT, cipher=TLS_AES_128_GCM_SHA256, bits=128/128

Then nothing else.

Hello

you know that it's possible to enable full log at the smtp level yes ? mailnews.smtp.loglevel <- All in config editor. Then tools / dev tools / error console. My guess: self-signed certificate (but I don't know why it would not be a problem for imap - maybe it's done differently for your dovecot ?)

Problem is resolved... I had to update the Fedora server to fix. Apparently they had a bug with sendmail and saslauthd
