Replace pithy comment with something more neutral. Thanks Gordon Rowell <gordonr@gormand.com.au> r548@jpeacock: jpeacock | 2005-07-02 07:24:21 -0400 Example patterns for badrcptto plugin - Gordon Rowell <gordonr@gormand.com.au> r586@jpeacock: jpeacock | 2005-07-09 06:54:47 -0400 Don't use varlog() directly unless you are passing all parameters. Don't try to log() anything during loading of logging plugins. r587@jpeacock: jpeacock | 2005-07-09 06:59:57 -0400 Cannot use new-style hooking with logging plugins (yet). git-svn-id: https://svn.perl.org/qpsmtpd/trunk@490 958fd67b-6ff1-0310-b445-bb7760255be9

check_spamhelo - Check a HELO message delivered from a connecting host.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Check a HELO message delivered from a connecting host. Reject any
|
|
that appear in the badhelo config -- e.g. yahoo.com and aol.com, which
|
|
neither the real Yahoo or the real AOL use, but which spammers use
|
|
rather a lot.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
Add domains or hostnames to the F<badhelo> configuration file; one
|
|
per line.
