How to log subjects of all incoming email?

[chcatz]

Hello,

I'm trying to achieve the same but in the tracking center, i don't see any subject being logged. Also, is it possible to export the tracking center output to CSV ?

1.Please check whether the line
$self->log (3, "$queue->{logid}: Subject: %s", PMG::Utils::rfc1522_to_html($entity->head->get ('subject', 0)) || 'No Subject');
is really inserted under “PHASE 2” part in the "/usr/bin/pmg-smtp-filter" file.

Then...
systemctl restart pmg-smtp-filter

2. Direct export is not possible.
But you can maybe use the "/var/log/mail.log" file.

Hello. The line works.
$self->log (3, "$queue->{logid}: Subject: %s", PMG::Utils::decode_rfc1522(PVE::Tools::trim($entity->head->get('subject'))) || 'No Subject');
But non-ANSI symbols are not displayed in the log.

This line works better.
$self->log (3, "$queue->{logid}: Subject: %s", PMG::Utils::rfc1522_to_html($entity->head->get ('subject', 0)) || 'No Subject');
But it is much more convenient to immediately see the decoded text in the log.

When viewing, you can decode it like this.
cat mail.log | grep Subj | perl -MHTML::Entities -pe 'decode_entities($_);'

How to decode from HTML to UTF-8 immediately when writing to the log?
