I use Postfix 2.0.10 with TLS patch, cyrus-imapd 2.1.13, sasl 2.1.13
The problem is as follow:
When a message with russian charset characters (KOI8-R, WIN1251) in Subject
field arrives or is moved into the Sent Items folders by Outlook Express,
each russian character is replaced by an X (ex: Re: XXXX XXXX mazda 626
XXXX). I happens only when the Subject field is without charaterset
specification.
I dumped mailboxes with cyrdump, the Xes are in.
What can be wrog?
The problem is that 8-bit characters are not allowed in the header of an
RFC822 message. There are extensions designed to allow 8-bit
characters, by encoding the character set and a base64 or
quoted-printable representation of them. The problem is that Cyrus
cannot properly transform these messages to standards compliance since
it cannot know what character set was used, only that it wasn't
US-ASCII, so Cyrus chooses to either drop the message or replace all
8-bit characters with X depending on a configuration setting. There was
some discussion of hacking Cyrus to allow an administrator-supplied
default character set in the case of 8-bit data without a character set,
but the consensus of the developers seemed to be that was more an MTA
function than Cyrus, and nobody felt like doing a hack that would not be
accepted into the official source.
