My users often need to migrate from HotMail, so I tell them to use Outlook Express to drag the message from HotMail's WebDav folder to our IMAP folder. This would all be fine, except that OE keeps the 'From ' line when it does the copy, which Cyrus rejects as an invalid header (which is fair enough). As a short term solution I've removed the check from message.c so that these messages get accepted (try doing that with a closed source solution! ;-). A better option would be to have the option to specifically ignore the 'From ' header. I know procmail users amongst others have this same problem (based on browsing Google's Usenet archive), so although it's not strictly 'correct' it would help a lot of people out. My questions are: - What is the downside of my patch that removes the check for invalid header chars? - Could we add a compile time or imap.conf option to ignore 'From ' headers? - Is there an easier way to avoid this problem? Thanks for any suggestions, Jeremy
