[Fwd: [imp] Can't send messages though sendmail]

[Eric Rostetter]

Quoting EdwardSPL@ita.org.mo:

   ----- Transcript of session follows -----
550 5.1.2 [edward@123.com]... Host unknown (Name server: 123.com]: host not found)

Try the same command without the [ ] characters.  If it still fails, then
it is a DNS/hostname problem, meaning either you didn't configure your
/etc/resolv.conf, and/or you need to add 123.com to your /etc/hosts file.
