Really slow mysterious speeds are nearly always due to massive packet loss and 9/10 times this is a duplex mismatch or failing network card. Curious huh... Ed W
[Dovecot] Folders and Mail within Folders
Hello. How do I make folders that can contain mail and additional folders? Thanks, -- Elizabeth Greene IT Manager, GlobalOptions FSIU Division 615-665- (Office) 615-456-9813 (Mobile)
Re: [Dovecot] graceful failure when some folders are not available...
Did I miss a reply on this? We're considering modifying Dovecot, but would like opinions before going down the wrong path...

Quick question in the hopes that someone knows the answer, before I dig in the code some more. In testing a new setup with some long-term archival mbox-format mailboxes stored on an NFS mount, we've found the following: if the mount is unavailable for any reason, the user cannot log into their email at all. Dovecot says: stat() failed with mbox foo and dies. This is coming from Perhaps dies was too strong. In fact, Dovecot does not die, but the client perceives such as it is told this upon trying to log in: The current command did not succeed. The mail server responded: Internal error occurred. Refer to server log for more information. And in fact your tests (below) reproduced this. The problem with this is that if even one file or directory within the user's IMAP folder space is currently unavailable (due to an NFS server being down), the user cannot log in at all to access any of their other folders. In out scenario, we would prefer that the user simply not see the folders (treat the error the same as file not found). BTW, the errno seen is ETIMEDOUT (we are soft mounting the NFS filesystem in question). Any thoughts on how we can accomplish this? We don't normally expect this NFS filesystem to become unavailable, but when it is, we don't want it to prevent all users from being able to log in, since this NFS filesystem only holds folders of an archival nature. the mbox sync checks. (It's possible the same happens with a maildir folder--I'm just specifying mbox because that's what we've tested with so far). It shouldn't die. Maybe your client kills the connection? I tested this by making the stat() call always fail with EIO: x select inbox x NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:24:48] x status foo (messages) x NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:24:58] Or even if the mailbox is successfully opened and after that: x noop * NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:27:31] x OK NOOP completed. -- Steven F.

Well, with RedHat it can actually be that old. RHEL4 -which is still supported- still uses 0.99, that is something like 4 or 5 years old. Not only that, it can also use a surprisingly confusing version number. Right now, package's name is dovecot-1.0-1.2.rc15. What's this? 1.0-rc15? In order to know the exact version you're running, run dovecot --version.

Re: [Dovecot] Problem with bodystructure/partial fetch using 1.1*
I somehow solved this compiling with gmake instead of make. I think it's related to libiconv and not to Dovecot. Sorry for the confusion. - Mikkel On Wed, October 17, 2007 1:55 pm, [EMAIL PROTECTED] wrote: Hi there I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an SQL database and no errors related to this issue are written to the logs (actually I get no errors at all). I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to dovecot 1.1b2 (same issue with 1.1b3). BODUSTRUCTURE only returns information from the first section (with incorrect content-type/disposition) and discards everything else. This problem is somehow related to deliver; IMAP returns the correct BODYSTRUCTURE for e-mails received before the upgrade, but an incorrect for ones received after the upgrade. This tells me that IMAP is working properly but somehow the MIME sections are being corrupted doing mail delivery (if I fetch the complete body nothing seems to be wrong). Also if I fetch a section something is not right - instead of just the section I get part of the Content-type header as well (but only half the header). Obviously this makes various webmail clients go somewhat crazy while Outlook/Thunderbirds dont mind (since they fetch the complete body and do the MIME parsing themselves).

[Dovecot] In 1.1.beta3, COPY cmd results in msg with Content-length: 0 and no text
I run Thunderbird with message filters that sort mail into other folders, and this has killed me for the day. COPY commands (and I have verified this with a manual test) result in the message headers coming out correct but the body totally missing. Is this a known issue being addressed? Thanks Eric Weaver
