You can check ~/.muttrc file to see what it is using to send emails. If it is using sendmail or esmtp, then in .muttrc file where it specifies sending program you can append -X /path/to/log/file. That will output the whole SMTP dialog to that log file. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
