I run ifmail on my node (2:5020/118). When I send a mail, ifmail
places a line 'From: email@example.com' at the beginning of it.
When the mail arrives to my hub (2:5020/400) which runs ifmail, too,
the originating address gets rewritten as ifmail gets the 'From:...'
line and "Yar.Tikhiy@f118.n5020.z2.fidonet.org" ceases to exist.
"Yar.Tikhiy@f400.n5020.z2.fidonet.org" appears instead of it.
Replys get delivered O.K., of course, but I feel some discomfort.
So, I think it would be a right thing not to write the 'From:...' line
for messages from local users (i.e. with myfqdn as the host part of the
RFC-822 address) but to handle the replys to such messages by means of
aliases or the 'MatchGECOS' option of sendmail.
It is no technical problem for me to make ifmail behave so, but I'd
like to hear your opinions on the ideological correctness of that.
