You need to look¹ at exim's logs (/var/log/exim4/mainlog, /var/log/exim4/mainlog.1 and /var/log/exim4/mainlog.*.gz) to see what it's trying to send. There should be a line where mutt hands your email to exim, looking like: DATE TIME UNIQUESTRING <= your-from-address U=username … message-ID the string of interest ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ That should be followed by: DATE TIME SAMESTRING => to-address A=this B=that … Compare these lines for a successful email, which finishes with: … … C="250 2.0.0 Ok: NNNN bytes queued as 12AB34CD56E" DATE TIME SAMESTRING Completed and those for an unsuccessful one. > what does "test-server.example.net" refer to? Sorry for my ignorance. Read https://en.wikipedia.org/wiki/Example.com ¹ You'll need to be in the adm group, or use sudo, or be root. Cheers, David.
