I've taken a look into my sendmail 'mc' file and found this: ----- BEGIN SNIP ----- divert(0) VERSIONID(`$FreeBSD: src/etc/sendmail/freebsd.mc,v 1.27 2002/10/16 22:52:56 keramida Exp $') OSTYPE(freebsd5) DOMAIN(generic) FEATURE(access_db, `hash -o -T /etc/mail/access') FEATURE(blacklist_recipients) FEATURE(local_lmtp) FEATURE(mailertable, `hash -o /etc/mail/mailertable') FEATURE(virtusertable, `hash -o /etc/mail/virtusertable') dnl Uncomment to allow relaying based on your MX records. dnl NOTE: This can allow sites to use your server as a backup MX without dnl your permission. dnl FEATURE(relay_based_on_MX) ----- END SNIP ----- Looks as if it's disabled. newbie_question() { BTW, how can I check if somebody specifies me as his MX? ;-) } Regards, Martin -- Martin Möller http://www.bsdsi.com/ GnuPG/PGP DSA ID: 0x3C979285 ICQ # 82221572 I do not accept unsolicited commercial mail.
