Mail::Milter::Module::ConnectRegex - milter to accept/reject connecting hosts matching regex(es)
use Mail::Milter::Module::ConnectRegex; my $milter = new Mail::Milter::Module::ConnectRegex('^foo$'); my $milter2 = &ConnectRegex(qw{^foo$ ^bar$}); # convenience $milter2->set_message('Connections from %H disallowed');
This milter module rejects any connecting host whose hostname or IP address matches user-supplied regular expressions. It can also function as a whitelisting Chain element; see accept_match().
accept_match()
new(REGEX[, ...])
Accepts one or more regular expressions, as strings or qr// precompiled regexes. They are tested in sequence, and the first match terminates checking. Note that all IP address literals will be enclosed in [square brackets]; so to test an IP address rather than a hostname, ensure those brackets exist:
^\[ADDRESS\]$
accept_match(FLAG)
If FLAG is 0 (the default), a matching regex will cause the connection to be rejected.
If FLAG is 1, a matching regex will cause this module to return SMFIS_ACCEPT instead. This allows a ConnectRegex to be used inside a Mail::Milter::Chain container (in accept_break(1) mode), to function as a whitelist rather than a blacklist.
ConnectRegex
Mail::Milter::Chain
accept_break(1)
This method returns a reference to the object itself, allowing this method call to be chained.
set_message(MESSAGE)
Sets the message used when rejecting connections. This string may contain the substring %H, which will be replaced by the matching hostname or IP address.
%H
In Sendmail 8.11 and 8.12, a milter rejection at "connect" stage does not allow the reply message to be set -- it simply becomes "not accepting messages". However, this module still attempts to set the reply code and message in the hope that this will be fixed.
