If CSF (ConfigServerFirewall) is off I can send mail using sSMTP (SimpleSMTP) (via Gmail), but when I turn on CSF, sSMTP doesn't send mail, it just hangs.
When I use
watch netstat -a then try to send mail, this is what i see:
tcp6 0 1 2001:41d0:8:e17e::33447 we-in-x6d.1e:submission SYN_SENT
33447 changes to a different number every time I send mail.
Anybody knows how to use sSMTP with CSF?
