Hello,

The version packaged on Bullseye is slightly out of date, I have filled
a bug report:

https://bugs.debian.org/985654

Thanks to the maintainers for their hard work!

Hello,

I am developing a hosting platform on Debian Bullseye, with Dovecot
amongst other tools.

I am trying to use the xapian full test search plugin, but I can see
the attachments are skipped:

This is what I have in the logs when running the indexing in verbose
mode:

Especially thos line:

doveadm(camille): Info: FTS Xapian: Skipping part of type 'text/csv'
and disposition 'attachment; filename="file.csv"'

I have seen this as a bug on fts-xapian:
https://github.com/grosjo/fts-xapian/issues/68

Which then references a PR on Dovecot core itself:

https://github.com/dovecot/core/pull/155

Any idea on how to use xapian with non-text attachments ?

Thanks a lot for your help!
