Using dovecot 1.2beta (but earlier versions should behave similarly) we
have a problem in conjunction with empty To: headers and the RT request
tracker.
RT sends mail out using Bcc: and no To: header at all. To make some
mailers happy one can configure to send a dummy To: header, which we do.
Our To header looks like:
To: "AdminCc of rt Ticket #123456":;
The message_address_parse function called with the TRUE flag
(triggers add_fixed_address) in dovecot changes that to
To: AdminCc of rt Ticket #123456: missing_mail...@missing_domain ;
and then at least alpine does use that invalid address as Cc: address when
replying. If the mail is stored in a local folder, i.e. does not get
fetched via IMAP then the To: line is displayed as is and a reply does not
result in an errorneous Cc:
This behaviour is at least inconsistent from a user point of view. Is
there some advice other than change the RT mail header generation?
(other mailers seem to copy the To: line unaltered which results in an
invalid address as well, therefore I admit that the real problem is with
RT)
