Hi folks,

currently I'm running Dovecot 1.2.1. Compiled from source on Fedora 10 Linux 32 Bit (all patches). Clients are Pine 4.64, Thunderbird 2.0.0.22 and Mutt 1.5.20 (using "=b" for server-side searching).

When a message contains the text "under_score" and I let the server search for it, Dovecot does not find it in messages with a Content-Transfer-Encoding of "quoted-printable".

It works perfectly well with messages without Content-Transfer-Encoding.

If I replace the underscore with a space (search for "under score"), it magically matches on "under_score" (no space but underscore). Looks like something goes wrong with the encoding/decoding of quoted-printable (sorry, haven't tried with base64).

Example: Dovecot does not find "under_score"

Example: Dovecot find's "under_score" without problems

The problem is not new to Dovecot 1.2.1 but exists in the 1.1 series as well.

Greetings, Andreas
