Package: syslog-ng-core
Version: 4.8.1-5
Severity: normal

Dear Maintainer,

In order to support SMTP as a destination, one needs the SMTP Syslog NG driver, aka "syslog-ng-mod-smtp".

I see support for SMTP has been disabled on Ausgust 18, 2024: "Disable SMTP destination plugin for now".
Do you have any particular reason for not having re-enabled it since then (and included it in Trixie) ?

I have personally successfully re-enabled this support using the Debian Trixie source:
- in debian/control: add libesmtp-dev in Build-Depends
- in debian/control: uncomment the "syslog-ng-mod-smtp" package entry
- in debian/rules: replace --disable-smtp by --enable-smtp

I installed the resulting custom-built packages (including syslog-ng-mod-smtp 4.8.1-5+1custom13u1, as you
can see below) and confirmed the SMTP module/driver _does_ work.

Would you consider re-enabling it for future releases ?

Thanks and best,

Cédric
