[Dovecot] Dovecot and Outlook - IMAP Timeout error
by Phillip T. George 11 May '07

11 May '07

Hey guys, I'm having a problem with Dovecot and Outlook. I'm testing with Outlook XP (2002), but the problem occurs with Outlook 2003 as well. I'm using Dovecot 1.0.rc28. The specific error generated (for IMAP) is: "A connection to the server could not be established. <servername> is now in offline mode." In the details: "There may be a server or network problems or your timeout interval may be too short. Protocol: IMAP Server: <servername> Port: 143" It is set up with a POP3 account and an IMAP account within Outlook -- using the same physical email account. The IMAP portion is only used for spam / ham submission, while the POP3 is used for downloading the actual email. The account on the server being used is named "me2.pg.east.eacsd.com" I have a single IMAP account set up in Thunderbird, which is using the account name "me.pg.east.eacsd.com". All mail that is received at "me.pg.east.eacsd.com" is forwarded to "me2.pg.east.eacsd.com" to generate some traffic. Here is the snippet of the mail log which involves me2.pg.east.eacsd.com ( | grep me2.pg.east.eacsd.com | grep -i imap): Apr 25 02:40:11 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:40:13 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected in IDLE Apr 25 02:41:10 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected: Logged out Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:50:49 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:50:50 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected There's more before that, but I'd figured that would be enough: Apr 24 17:18:05 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:34 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:42 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:27 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:42 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS Apr 24 17:43:18 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS As you can see from the logs, Thunderbird didn't have a problem, which eliminates the possibility of a bad net connection (I'd assume...but I could be wrong). The problem occurred at 3AM. Some people during the day can get it every hour or so. I was able to get it to occur twice (the first time is not shown in these logs). My questions. . . 1. Is there any way to fix this Outlook problem? I have all of the outlook workarounds enabled (along with some for Netscape): imap_client_workarounds = delay-newmail outlook-idle netscape-eoh pop3_client_workarounds = outlook-no-nuls oe-ns-eoh 2. Should Outlook really be connecting and disconnecting that often? 3. Could the problem be occurring because of POP3 and IMAP being used by the same account, and the quick downloading of email via POP3 is eliminating the email for IMAP, thereby causing inactivity in IMAP? Is there a workaround or a known Outlook settings to fix this? Thanks, Phillip

[Dovecot] Troubleshooting - another suggestion...
by Charles Marcus 11 May '07

11 May '07

Hi Timo, I'm the one who suggested the '-n' option to capture the actual config settings that the running dovecot process was using (ala postfix), and you implemented it very quickly - so thanks for that! Now, I'd like to suggest an enhancement... Many people still do not provide basic things like dovecot version, and there are secondary config files like dovecot-ldap, whose settings are not included in the dovecot -n output. How difficult would it be to add these to the output so that the output would include the running dovecot version, as well as any extra config settings from any other files that are loaded when dovecot starts? It would sure make it easier, both for us troubleshooting on our own, and when asking for help on the list. Many thanks, and terrific job on 1.0! Now all dovecot lacks is full support for IMAP ACLs/shared folders, and support for single-instance storage, and it will have no real competition... -- Best regards, Charles

[Dovecot] maildir file name flags out of order?
by Aaron Solochek 11 May '07

11 May '07

I was trying to figure out why my false-positive spam messages were being tagged as "personal" by thunderbird, and I noticed a possible problem. According to DJB: http://cr.yp.to/proto/maildir.html > New flags may be defined later. Flags must be stored in ASCII order: e.g., "2,FRS". Looking at my maildir, I am seeing flags out of order, such as "2,Sdae" Shouldn't that be "2,Sade"? -Aaron

[Dovecot] Disconnected for inactivity in reading our output top=0/0
by Chris Gosley 11 May '07

11 May '07

Would someone please help with this error. Using: dovecot-1.0-2.rc28.fc6 On: Fedora Core 6 130 users all connect remotely via ADSL to server to pop their email. None of them have any problems at all with pop3. 3 users in one office, connect to the server via a NAT'd ADSL. Intermittently those three users will get a timeout error, Logfile shows: Apr 19 12:50:53 mail dovecot: auth(default): pam(vu0095,165.228.62.107): lookup service=dovecot Apr 19 12:50:53 mail dovecot: auth(default): client out: OK 1 user=vu0095 Apr 19 12:50:53 mail dovecot: auth(default): master in: REQUEST 376 12300 1 Apr 19 12:50:53 mail dovecot: auth(default): passwd(vu0095,165.228.62.107): lookup Apr 19 12:50:53 mail dovecot: auth(default): master out: USER 376 vu0095 system_user=vu0095 uid=580 gid=580 home=/home/vu0095 Apr 19 12:50:53 mail dovecot: pop3-login: Login: user=<vu0095>, method=PLAIN, rip=165.228.62.107, lip=203.36.211.209 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected for inactivity in reading our output top=0/0, retr=1/0, del=0/2, size=25266 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected: Logged out top=0/0, retr=2/25393, del=2/2, size=25266 99% of the time everything is perfect, it is only the three users in the one office that get this error, it is of course the head office for the customer and so they are very upset, because they get timeout errors on their email clients. They are using different versions of outlook, and outlook express, I have deactivated all nortons email scanning etc Have set the three email clients to pop mail at different times, eg. 7, 13, 17 minutes to try an avoid the possibility of simultaneous pop requests from the one IP address.

[Dovecot] read only bug?
by Nagyon Almos 11 May '07

11 May '07

Hello All, I have been still struggling with the read only maildir and I think I found something: dovecot wants to rename a file but I/it have/has no rights to do that: dovecot: 2007-05-04 21:30:14 Error: IMAP(bela): rename(/home/store/oldmails/.personal/cur/1154939281.00005.pc1.S=1879:2,S, /home/store/oldmails/.personal/new/1178307014.P8610Q0M347618.pc1) failed: Permission denied Why dovecot wants to rename it? It is really a read only directory. Regards, A. ______________________________________________ 2600 állásból Te is találsz megfelelőt!

[Dovecot] read only maildir
by Nagyon Almos 11 May '07

11 May '07

Hello All, I try to set up a read only maildir just as in the wiki, to no avail. The extra (public) namespace shows up but I can not susbscribe to it (in thunderbird) or if I change to that "directory" (in mutt), it is empty. Is it the problem mentioned in the wiki (SharedMailboxes#Subscriptions)? If yes, how can I see/use a folder which is not subscribeable? Any help would be greatly appreciated.

[Dovecot] Error: Master request X not found
by Jordi Moles 11 May '07

11 May '07

*Hi, I've been getting the following error from time to time since i started to use dovecot more than one year ago: dovecot: May 07 19:57:24 Error: auth(default): Master request 88729.43523 not found I haven't stopped upgrading dovecot with the hope that this would be a bug and would be fixed some day, but with v1.0.0, i keep getting the same error. It just happens from time to time. Some of the users of my system complain about not being able to get to see their mails, and it is always at the time when this error is logged. Surfing through many forums, i came across with a cause that many people point to: "client closed connection at the exact same time master was logging it in" i don't know if this is what happens to my system, to be honest, i don't have a clue how to check that, i just would like to know if somebody has come up with a solution for this problem, as it seems many people are still trying to face it. thank you. ***
