I use exim locally rather than direct SMTP sending from mutt, so can't help directly. However, perhaps the `swaks` command line tool could be helpful in nailing down the issue? The Debian repo entry is: Description-en: SMTP command-line test tool swaks (Swiss Army Knife SMTP) is a command-line tool written in Perl for testing SMTP setups; it supports STARTTLS and SMTP AUTH (PLAIN, LOGIN, CRAM-MD5, SPA, and DIGEST-MD5). swaks allows one to stop the SMTP dialog at any stage, e.g to check RCPT TO: without actually sending a mail. . If you are spending too much time iterating "telnet foo.example 25" swaks is for you.
