[Dovecot] problem with charset and encoding

Hello Steffen,

The mail storage is the same, Maildir.

The messages do not look weird, only the special characters.

When you're saying to remove old cache files, do you mean dovecot index files in the Maildir directory (dovecot* files)?

I haven't done anything but deleting those files, which were re-created when starting new session in dovecot.

I have tried creating a mailbox with that information and the view was correct in TB, OL and Webmail. So the problem might be in that mailbox.

Do I have to do something else to "repair" this mailbox?

Thank you very much,
Kind regards.

Did you upgraded the mail storage, too?

Do the messages look wired in other ways, e.g. do they have header lines at top?

No, I don't think so. The client renders the message, Dovecot should not alter its content.

Do this happen for new accounts, too? If not, maybe you need to remove the old cache files.

What mail storage do you use? With Maildir you could easily create a new mailbox and drop a file with:

==== START
Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: quoted-printable
Subject: Test
Message-ID: <test2344434 at localhost>

Su c=F3digo de activaci=F3n

there then view it with a client.
