While it is true that port 25 shows as filtered in the nmap output
(meaning OP will not be able to receive mail), this does not address
their current problem. They are connecting on the submission port, 587.
The submission port is correct for users on residential / otherwise
dynamic connections to talk with their SMTP server (i.e. for submitting
mail for relaying to other servers). And, indeed, it does show as open
in the nmap output.

Are you setting $my_pass and $my_user in your .muttrc? mutt doesn't
recognize these settings. It shouldn't affect sending mail, but I wonder
what these lines are doing.

Without seeing the rest of the smtpd configuration and log files, it's
difficult to determine what the problem could be. This configuration is
similar to what I use for my own server which works without issue. Are
you sure that $ipv4 and $ipv6 are correct? I use interface names in my
configuration, which are easier to get right than IP addresses
(especially v6 addresses).

Have you checked your logs in /var/log/maillog when you try to
authenticate with mutt/thunderbird? This should provide some more detail
about what's going wrong.
