I've modified the script /etc/ppp/ip-up to set /var/qmail/control/helohost and
/var/qmail/control/smtproutes with the proper information; it also starts
qmail. I've enabled artificial smtp routes because the first attempt made
with helohost and maildirsmtp did not work. Unfortunately the second attempt
failed, so I've added several folder hooks in .muttrc (one for each maildir):
folder-hook monrif 'set sendmail="/var/qmail/bin/qmail-inject\
-ffcasadei@monrif.net"'
...
Needless to say, also the third attempt failed! I've read carefully the error
messages returned by the mail system at tin.it and finally I've found the
problem:
Reporting-MTA: dns; fep24-svc.tin.it
Arrival-Date: Tue, 27 Jun 2000 18:43:59 +0200
Received-From-MTA: dns; a-tr4-36.tin.it (212.216.170.163)
Final-Recipient: RFC822; <freebsd-questions@freebsd.org>
Action: failed
Status: 5.2.0
Remote-MTA: dns; freebsd.org
Diagnostic-Code: smtp; 450 <fep24-svc.tin.it>: Helo command rejected: Host not
found ^^^^^^^^^^^^^^^^^^
In fact the reverse DNS lookup on fep24-svc.tin.it fails:
casimiro> host fep24-svc.tin.it
Host not found.
This is the fourth (and the last, I hope) attempt: I try to send this message
while connected to Tiscali (and thus using smtp.tiscalinet.it).
If you (and me too) see this message then it works!! :-))
