I am not sure if this is a bug in mail.app, or a configuration I just can't find. It might also be a strange sideffect of GPGmail.
Mail.app correctly displays all e-mails on my IMAP server, except for the e-mails in my "Sent Messages" folder. In the sent messages folder it messes up åäö, in typical quoted-printable with wrong char-set fashion. They become Â‰ˆ.
When looking at the source of the e-mails it seems like the header generated by mail.app is correct:
Message-Id: <> From: To: In-Reply-To: <> Content-Type: multipart/signed; protocol="application/pgp-signature"; micalg=pgp-sha1; boundary="Apple-Mail-4--741321197" X-Smtp-Server: smtp.example.com Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v936) Subject: Example subject Date: Fri, 26 Mar 2010 10:14:14 +0100 References: <> X-Pgp-Agent: GPGMail 1.2.0 (v56) This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --Apple-Mail-4--741321197 Content-Type: text/plain; charset=ISO-8859-1; format=flowed; delsp=yes Content-Transfer-Encoding: quoted-printable <Text here with =E5=E4=F6> --Apple-Mail-4--741321197 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.12 (Darwin) iEYEARECAAYFAkus62kACgkQlIRLofxhDjYnnwCcDmCXuMGsKlh3a418s12coJgn 36sAoKMdkP3+g/OMK+Ps7AbjQq4Nbqzv =XMko -----END PGP SIGNATURE----- --Apple-Mail-4--741321197--
How can I get mail.app to use the correct charset?
Some more test results:
- Thunderbird has no problem displaying the messages.
- When I send a message to myself it displays correctly in the Inbox, but incorrectly in the Sent folder. But: moving the message from Sent to Inbox does not change the erroneous formatting.
- Turning off signatures makes the messages display correctly in the Sent folder as well. The only difference I can see (beyond headers added in transfer), is the
This is an OpenPGP/MIME signed message (RFC 2440 and 3156)line added before the first mime block.
