Hi. I just installed a fresh RH 6.0, and I can't send mail
due to relaying restrictions. Although /etc/mail/access
has localhost etc in it., looking through the logs, I see
that the relay request is for "relay=IDENT:rab@localhost"
I suppose it is the IDENT which causes the problem, since
localhost is certainly in the access file.
Adding "127.0.0.1" to /etc/mail/access and running makemap
solves the problem.
Added 127.0.0.1 to /etc/mail/access in sendmail-8.9.3-14.
