They look sort of like what alpine would produce. Do your clients have direct filesystem access to the INBOX spool? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] lock file strangeness
by McGraw, Robert P 25 Jul '12

25 Jul '12

We are running dovecot-1.2.10 on a Solaris 10 x86 host. Starting on July 24 I started seeing the following type lock files I the /var/mail directory. -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138908.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138907.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138906.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138905.28535.hardy.purdue.edu They are being created by only three of our users. What is common with the three users is that they are using alpine mail client. Again these just started on July 24. We have over 300 user and a lot of them use alpine but only three users seem to generate these lock files. Can some one tell me what and why these are being created and why they are not getting destroyed? Thanks Robert _____________________________________________________________________ Robert P.

[Dovecot] deleted-to-trash plugin problems
by Steve Platt 24 Jul '12

24 Jul '12

We have a user who wants to use Outlook with our Dovecot IMAP server but doesn't like the way Outlook handles deletion with IMAP. Ironically she would like Outlook to move the message to her Trash folder, just like Outlook does with "local" folders, I guess. So I enabled the "deleted-to-trash" plugin (v0.3) on our Dovecot 1.2.17 server (built for SPARC, solaris 10, btw). The problem is that it doesn't seem to work; the message doesn't even appear to get marked for delete. The imap log says: "opening Trash succeeded" and then nothing else! I have found that there is a copy of the message in .Trash/tmp/ suggesting that the plugin may be bailing out part way through. Has anyone any idea what's wrong please? I'll attach the output of dovecot -n ... Thanks, Steve

Morten Stevens <mstevens(a)imt-systems.com> writes: > So it is now RFC compliant. Anyway I think delaying mail traffic is not > a good solution. Well, OK, if you not keen on greylisting, you can try greet pausing, which introduces a shorter delay. It tests a bot's patience by inserting a pre-HELO pause. RFC allows 5 minutes before timeout. This is last week's stat for one of my mail server and the count of early-talker or early-disconnecter, almost all of which are bots. A greet pause of over 20s dumps a lot of bots. Expect to whitelist the odd server here and there because they've tuned their servers to some aggressively small RFC non-compliant timeouts.

This might be misleading since this is a feature request and not a bug.

That's another problem with the poor IT guy trying to assemble bricks from different vendors: when he finally is heard, the answer is "uhm, the feature you requested fail beyond the scope of my brick. I'm sorry, I can't do that", even when there is a proposed patch available! If you read carefully all my referenced links you'll find one that is listing other imap servers that support it. From what I've tested, at least one implementation has done this as a global pre-user execution of a script (dovecot) > > I don't see any bugs about a default-user-sieve-script. *BUT* > imapd.conf does offer this option [IMPLEMENTED]: > autocreate_sieve_script: <none> > The full path of a file that contains a sieve script.

Unfortunately that feature only addresses PROVISIONING of data, which is quite unuseful since cyrus mail admins do this with the auto-* uoa.gr patches (that's another pain that devs refused to include for a long time) - What it lacks is the ability to handle CHANGE (change of default script, or alter existing user scripts).

[Dovecot] Couple of questions about the logs
by Steve Campbell 23 Jul '12

23 Jul '12

The log entries for imap disconnection shows a "bytes = x/y" format where the x equals bytes sent from client and y equals bytes received from client. Can someone explain that a little better to me, please? In an imap account, does this "y" represent the size of the header information being returned to the client or the amount of data of the email mailbox? Also, is there a way to tell if an email has been deleted (or marked for deletion) when using an imap client? Here's the situation: I've got a user who uses imap when using his phone and webmail. When in the office, he uses a pop3 client on his desktop. He indicates he's missing some emails from the weekend when first turning on his desktop. I know of no way to discover if he's deleted and then purged email from his mailbox using imap clients. I've checked the logs and he does not access his mailbox simultaneously from any of the 3 clients. I can find 31 emails he received since his last pop login on Friday until his first pop login on Monday. The pop login indicates he received only 27 emails during the pop retrieval. I'm a little lost here. Any help would be appreciated in interpreting the logs or suggesting how this might have happened. thanks steve campbell
