Tcp.smtp
Back
/etc/tcprules.d/tcp.smtp is a 2 line (default toaster) file that orchestrates many of the QMT functions. It is the traffic cop in a busy intersection, controlling SMTP processing alternatives.
If you're running another MTA in concert with QmailToaster, or you have an unusual or complicated setup, the following might not be applicable to you. If that is the case, you should take your problem straight to the mailing list. Hopefully this page will eventually cover advanced configurations as documented by those who have such requirements.
Reminder: if you make changes to tcp.smtp, execute the following afterwards to activate the changes:
# qmailctl cdb
You do not need to stop and start qmail when only regenerating the .cdb files.
Stock (default) tcp.smtp file Your default tcp.smtp file on a fresh install looks like this (backslashes are for display purposes only, do not include them or newlines or extra spaces in the file - there are two and only two lines here):
127.:allow,RELAYCLIENT="",RBLSMTPD="" :allow,BADMIMETYPE="",BADLOADERTYPE="M",CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="10",QMAILQUEUE="/var/qmail/bin/simscan"
Line 1
127.:allow - Allow localhost RELAYCLIENT="" - Allow relaying without authentication
Line 2
(empty):allow - Allow anyone without to deliver locally, no relay BADMIMETYPE="" - Warlord patch BADLOADERTYPE="M" - Warlord patch CHKUSER_RCPTLIMIT="50" - Max recipients any more are denied CHKUSER_WRONGRCPTLIMIT="10" - Max non-existent recipients any more denied QMAILQUEUE="/var/qmail/bin/simscan" - Simscan is the queue and will call qmail-queue
