Mail Relays

(before v.2.4)


To configure POP-before-SMTP for qmail+vpopmail you should make the following steps:

Add to your rc.local (or other startup script) the following lines:

/hsphere/shared/bin/tcpserver -H -R 0 pop-3 \
/hsphere/local/var/qmail/bin/qmail-popup your.domainname \
/hsphere/local/var/vpopmail/bin/vchkpw \
/hsphere/local/var/qmail/bin/qmail-pop3d Maildir &


/hsphere/shared/bin/tcpserver -H -x
/hsphere/local/var/vpopmail/etc/tcp.smtp.cdb \ -u [id_qmaild_user] -g
[id_nofiles_group] 0 smtp
/hsphere/local/var/qmail/bin/qmail-smtpd 2>&1| \
/hsphere/local/var/qmail/bin/splogger smtpd 3 &

[-H] options is needed so that tcpserver would not try to lookup remote host name in DNS (as it might cause the timeout or delays when sending mail from some IPs). This option may be substituted for [-t 1]. This will result in an attempt to lookup the host name, yet it will timeout in one second, thus minimizing the delay and timeout posibility.

Next, make sure that smtpd is not in inetd.conf.

Also, to add a valid host (IP) that can relay mail through this mail server, go through the following steps:

Add this IP into tcp.smtp file in the following format:,RELAYCLIENT=""
The above line allow clients from
The below line allow client from 127.* subnetwork

Type and run: tcprules ${path}tcp.smtp.cdb ${path}tcp.smtp.tmp < ${path}tcp.smtp

You should add the following line to the crontab :

30 * * * * /hsphere/local/var/vpopmail/bin/clearopensmtp

to clear IP database every hour (or another time period).

Restart these services.
