From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922 Description of problem: Macintosh Eudora clients fail when connecting via POP to dovecot on FC3. A possible explanation is at: http://www.dovecot.org/list/dovecot/2004-September/004718.html "Could be that it's trying to login using AUTH PLAIN command, which Dovecot 0.99 doesn't really support correctly with POP3. 1.0-tests have fixed that." Version-Release number of selected component (if applicable): dovecot-0.99.11-1 How reproducible: Always Steps to Reproduce: 1. run dovecot on FC3 server 2. try to connect via POP from Eudora on a Mac Actual Results: "Unsupported authentication mechanism" message. Additional info: IMAP works fine, other POP clients work fine.
Timo: On the presumption that this is fixed in 1.0 I just did a diff between 0.99-11 and 1.0-test59 and looked for diffs in the pop3-login auth code. Hmm... quite a few. Do you happen to recall what the specific fix/issue was or is just a case where in a largely new body of code things just seem to work now that didn't before? I don't have an easy way to test this anyway, I'd have to locate a Mac (doable) and configure things. I'm also wondering if this shouldn't just wait for the official 1.0 release. Do you anticipate that being soon?
Fixed in 0.99.12: - POP3: Don't return PLAIN in SASL list. We don't support initial SASL responses, so it only breaks with most clients that try to use it.
If the fix is in 0.99.12 - and presumably not a huge change - is there any chance of an update? I have a server deployment which needs this. (I'm surprised more people haven't been bitten by this - Eudora is still pretty popular on Macs.)
This bug also affects RHEL4 and no update has been released for it. I had to build the rawhide FC4 dovecot which fixes the problem and hasn't appeared to break anything else yet.
Note, for RHEL4 the fix is contained in errata RHBA-2005:237 which as far as I can tell is scheduled for RHEL4-U2
A fix for FC3 was released in fc3-updates, dovecot-0.99.13-3.FC3 released on 2005-01-17, closing ...
My RHEL4-U3 install still shows dovecot-0.99.11-2.EL4.1 as the most recent dovecot version, we're still hitting this bug. Can't find any mention of RHBA-2005-237. What happened?
