tcp.smtp and qmail-smtpd/run script question

Post #1 of 3 (1336 views)

People,

These are the last lines I have in my qmail-smtpd/run script:

/usr/local/bin/tcpserver -v -R -H -l "$LOCAL" \
-x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
/usr/local/bin/spamdyke -f /etc/spamdyke.conf \
/var/qmail/bin/qmail-smtpd 2> /var/log/spamdyke.log

Now spamdyke is not allowing mail to be relayed from local machines -
physical, virtual and Docker containers.

I am wondering if there is some scripting magic for this run file which
will cause the ip addresses that are allowed to relay (ie the ones which
appear in tcp.smtp) to be skipped by the spamdyke check somehow? - some
sort of "if then / else / fi" thing?

Thanks,

Phil.

Sure. Write your own shellscript wrapper around spamdyke that basically
checks whether RELAYCLIENT is set; if so, it skips invoking spamdyke and just
executes the rest of the command line.

Then call that shellscript in place of spamdyke in the above command.

Just what I wanted! Thanks for that - actually I worked out a quick and
dirty way too - I ran another copy of tcpserver without spamdyke but
using port 2525 instead. Tt works when testing with telnet and swaks
(simulating the relay clients) but there is yet still a another problem
with my Discourse Docker container talking to the host which I have to
chase up in another forum . .

Regards,

Phil.
