Barca 2.5 hangs when receiving email (reproducable)

[Shark]

If a friend sends me an empty email Barca 2.5.0.3910 hangs after receicing it. I mean the login process hangs (without timeout), so no other emails can be retreived unless I log in with another email program (any works, tested with 3) and delete this empty email.

If I send an empty email to myself, all works without problems.

Configuration:

IMAP over SSL, Server Port 993, Leave Mail On Server turned off, Imap Folder is Inbox and Authentication Type is Plain

Email Content:

Code: Select all

I'm quite sure the problem happens if the sender of the empty email is on a linux/unix system.

I couldn't reproduce it here I'm sorry (though that doesn't mean much, as it might be due to many other possible causes besides the headers, and also the headers above are probably already processed by the email client you used to download with).

If you have access to the email while it's still sitting on the server, eg. through webmail, and it's possible to save it into some kind of raw format (.eml, .msg, sometimes even .txt), please save it from the server and submit it to helpdesk (http://www.pocosystems.com/support/).

The message is from webmail. Everytime someone sends me an empty email from a unix machine Barca hangs I have to login to my webmail account, delete this one email, after which Barca is able to get the other emails.

If I send an empty message to myself (from Barca) there is no hanging. So I was looking at the headers of the last empty emails that made Barca hang and there was either no User-Agent field or some Unix program as User Agent. I think the source of the problem is that there is no body at all combined with a missing Windows style linefeed (because the email text is in the Unix format).
