Issue BUG: minor bug in mailhandler - not reporting STDOUT message

[hitd]

A long time ago, i wrote some mailhandlers ( check email for viruses using ClamAV and Sophos AV; wrapper for renattach ( a program which renames appended files ) ...
works fine since about Plesk 10

Works still on current Plesk 18 with a minor bug:

See following smtp session:

sending failed: Net::CMD (Net::SMTP) DATAEND command failed.
Last server message was:5.7.1 Command rejected

Mailhandler was:

#! /usr/bin/perl -wtT
#

use strict;

use warnings;

print STDERR "REJECT\n";
print STDOUT "this should be seen during REJECT\n";

exit 1;

The other side should see "550 5.7.1 Command rejected - this should be seen during REJECT", not a reject without any comment. IIRC this works fine on earlier versions of plesk.

In my case my virushandler is affected, because it rejects the mail as expected, but don't deliver any cause to the other side. It's hard to guess why the mail couldn't be sent for the guys who try to send me a virus they don't know about.

handler is activated by

#! /bin/bash
#
# should called with domain.tld as parameter.like
# 
# test-on-script example.com
# ins Verzeichnis wechseln
cd /usr/local/psa/admin/bin

CFG=`echo "$1" | tr "." "_"`

Just updated my mailhandler for viruses. Because sophos for linux isn't available free in version 9 ( no updated anymore ), i've added support for plesk's own drweb. The limit of 10 mailboxes went away. Of course clamav is working too. People using a payed license of sophos should be able to use this handler too.

But, that's why i post in this old tread, the bug noted about a year ago is still in effect.

The documentation said, that a mailhandler can write a smal message if he reject the mail. Simple example above. So in the SMTP session this caused to inform the user on the other system, why this mail is rejected.
