Hello all, I am using sendmail (SuSE 8.0) in my laptop for mail delivery. SMTP is closed outside, I just use it to send my emails. I use the laptop at home and at office => I have two different network configurations. At home sendmail works excellent (localhost.montblanc.homeip.net). In the office I can not resolve the hostname for my laptop and sendmail rejects the mail deliveries. Actually, sendmail checks localhost.montblanc.homeip.net and my dns in the office returns the ip of my FW at home for any *.montblanc.homeip.net. Here you see a piece of log: Jul 22 13:14:03 petit sendmail[1430]: g6MBE394001430: from=pep, size=40, class=0, nrcpts=1, msgid=<200207221114.g6MBE394001430@petit>, relay=pep@localhost Jul 22 13:14:04 petit sendmail[1430]: g6MBE394001430: to=pep@serrano.net, ctladdr=pep (500/100), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=30035, relay=localhost.montblanc.homeip.net. [193.251.17.35], dsn=5.7.1, stat=User unknown How can I just RELY all local connections and bypass this host/user check? I have already tried to add in /etc/mail/access "localhost.montblanc.homeip.net OK". Cheers, Pep
