After upgrading from Debian 12 to 13 the installed Znuny-OTRS ticket-system stops processing the incoming tickets. The tickets reaches the system as mail via SMTP/procmail. Znuny-OTRS relies on Sisimai/Data for mail-processing, from an Znuny-OTRS log: OTRS-otrs.Console.pl-Maint::PostMaster::Read-10 Can't locate Sisimai/Data.pm in @INC (you may need to install the Sisimai::Data module) (@INC entries checked: /usr/share/otrs/Custom /usr/share/otrs/Kernel/cpan-lib /usr/share/otrs /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.40.1 /usr/local/share/perl/5.40.1 /usr/lib/x86_64-linux-gnu/perl5/5.40 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.40 /usr/share/perl/5.40 /usr/local/lib/site_perl) at /usr/share/otrs/Kernel/System/PostMaster/Filter/DetectBounceEmail.pm line 15. Sisimai/Data was included in Debian 12, libsisimai-perl 4.25.15-1 but not anymore in Debian 13, libsisimai-perl 5.3.0-1 Thanks for all your good work, Lars
Control: reassign -1 otrs2 6.5.15-2 Sisimai::Data and Sisimai::Data::* have been renamed to Sisimai::Fact, so we can't ship it anymore. I'm afraid, /usr/share/otrs/Kernel/System/PostMaster/Filter/DetectBounceEmail.pm will have to be adjusted to these changes in libsisimai-perl. Reassigning the bug. Cheers, gregor
Thanks for the hint with the changed module-name. Mail-processing works again with the following changes:--- /usr/share/otrs/Kernel/System/PostMaster/Filter/DetectBounceEmail.pm.ORIG 2026-08-26 08:13:15.067921021 +0000 +++ /usr/share/otrs/Kernel/System/PostMaster/Filter/DetectBounceEmail.pm 2026-08-26 10:26:12.396239507 +0000 @@ -12,8 +12,8 @@ use strict; use warnings;
