Those two processes are the client mqueue runner and probably a daemon listening only on localhost rather than on all interfaces. There is a minimum level of effort required to set up mail properly; at the least, read /etc/mail/README and set: sendmail_enable=YES ...in /etc/rc.conf.

It's not just that, but people who don't understand how mail transport works, shouldn't be running mail servers. I expect to deal with sendmail for as long as I administer Unix boxes, but alternatives like Postfix in particular would be my preference from a number of standpoints. I'm in the same position. I starting running alternatives to sendmail in the late 90s on systems that I knew I was always going to maintain, but for systems that would be passed to others to maintain, I stuck with installing sendmail because there was much more expertise. Now a- days, I'm happy to set up Postfix on such systems (but will still use exim for myself).

receiving mail
Newly installed FreeBSD-7.0. Sending mail to other hosts works. Receiving mail does not: Between host1 (non-freebsd) and host2 (freebsd 7), sending a mail from host1 to host2 (both in domain .domain.topdom) results in message 'Returned mail: see transcript for details: - The following addresses had permanent fatal errors - u...@host2.domain.topdom - Transcript of session follows - 550 5.1.2 u...@host2.domain.topdom... Host unknown (Name server: mailhost.domain.topdom: host not found) - host1 and host2 are both behind a firewall, but they are in the same zone (so firewall rules do not apply), both are even connected to same switch and their IPs are in the same subnet. Both have fixed IP address (not DHCP) mailhost.domain.topdom does not exist in DNS, but host1 can send mail to other mailservers all over the world. host2(FreeBSD): /etc/nsswitch.conf hosts: files dns /etc/resolv.conf domain domain.topdom nameserver UUU.VVV.WWW.ZZZ (correct ip address of a DNS nameserver) DNS is fully working on host2 (and on host1) According to the FreeBSD handbook I should be able to receive mail ? What can be missing here, how to remedy? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The fact that host1 can send mail anywhere else is irrelevant; fix the MX entry or make mailhost.domain.topdom real/reachable from host1.

Postfix/receiving mail through router problem
FreeBSD 4.8 Release hijra.homeunix.com Checking all the postfix conf files and everything seems to be in the right place. Thou this is my first time setting up a mail server so it's a learning experience for me. There are no errors in any of the log files anywhere. Telneting to port 143 and 25 everything is working fine. So I figured it must be a problem with my router I think. Checking maillog shows that mail is being queued coming in and I can send with no problem. My router is configure to automactically updated my ip to dyndns.org and it's assigned the same hostname hijra.homeunix.com as my machine. /usr/local/etc/postfix/main.cf myhostname = hijra.homeunix.com mydomain = hijra.homeunix.com mydestination = $myhostname, localhost.$mydomain, hijra.homeunix.com /etc/aliases alias_maps = dbm:/etc/aliases alias_database = dbm:/etc/aliases Hope this is enough information.

If mail comes in ok, and mail goes out ok then I'm not sure what problem you have. [Where's it being queued?] Hope this is enough information.
