[Dovecot] NFS and Filesystem quota
by Joseba Torre 11 Jul '07

11 Jul '07

Hi, I've recently moved my mailboxes to a NFS share (on an emc Celerra), and, as expected, the quota extensions no longer works. However, I've read that adding http://dovecot.org/patches/quota-rquotad.c to $DOVECOT/src/plugins/quota, adding a line to $DOVECOT/src/plugins/quota/Makefile.am and rebuilding, it should work again. Unfortunately, it doesn't compile in my RHEL 4.0: /usr/bin/gcc4 -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../../src/lib -I../../../src/lib-dict -I../../../src/lib-index -I../../../src/lib-mail -I../../../src/lib-storage -I../../../src/lib-storage/index -I../../../src/lib-storage/index/maildir -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/usr/kerberos/include -MT quota-rquotad.lo -MD -MP -MF .deps/quota-rquotad.Tpo -c quota-rquotad.c -fPIC -DPIC -o .libs/quota-rquotad.o quota-rquotad.c: In function 'debugmsg': quota-rquotad.c:50: warning: implicit declaration of function 'i_vinfo' quota-rquotad.c: In function 'rquotad_quota_add_storage': quota-rquotad.c:90: error: storage size of 'statbuf' isn't known quota-rquotad.c:97: warning: implicit declaration of function 'statfs' quota-rquotad.c:99: error: 'MNT_LOCAL' undeclared (first use in this function) quota-rquotad.c:99: error: (Each undeclared identifier is reported only once quota-rquotad.c:99: error: for each function it appears in.) quota-rquotad.c:104: error: 'MNAMELEN' undeclared (first use in this function) quota-rquotad.c:90: warning: unused variable 'statbuf' quota-rquotad.c: At top level: quota-rquotad.c:225: warning: initialization from incompatible pointer type quota-rquotad.c: In function 'rquota_get': quota-rquotad.c:256: warning: dereferencing type-punned pointer will break strict-aliasing rules quota-rquotad.c:267: warning: passing argument 3 of 'clnt->cl_ops->cl_call' from incompatible pointer type quota-rquotad.c:267: warning: passing argument 4 of 'clnt->cl_ops->cl_call' from incompatible pointer type quota-rquotad.c:267: warning: passing argument 5 of 'clnt->cl_ops->cl_call' from incompatible pointer type quota-rquotad.c:267: warning: passing argument 6 of 'clnt->cl_ops->cl_call' from incompatible pointer type quota-rquotad.c: In function 'rquotad_quota_root_update': quota-rquotad.c:275: error: storage size of 'statfsbuf' isn't known quota-rquotad.c:291: error: 'MNT_LOCAL' undeclared (first use in this function) quota-rquotad.c:275: warning: unused variable 'statfsbuf' make[4]: *** [quota-rquotad.lo] Error 1 make[4]: Leaving directory `/home/lgstosej/dovecot/dovecot-1.0.1/src/plugins/quota' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/lgstosej/dovecot/dovecot-1.0.1/src/plugins' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/lgstosej/dovecot/dovecot-1.0.1/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/lgstosej/dovecot/dovecot-1.0.1' make: *** [all] Error 2 Any help?

[Dovecot] Migrating subscription lists
by Stewart Dean 10 Jul '07

10 Jul '07

I thought this would be relatively straightforward....I would create .subscriptions by doing an ls -1 of ~/mail. I'm running into some problems. 1) the ~/mail directories haves directories in them for 5% of the accounts! AFAIK, our mail sevice has always been UWIMAP with mbox format INBOXes, and it was my understanding that the mbox format is flat and NOT hierarchical and thus I'd have thought that ~/mail would be all folders and wouldn't have a directory with folders in it. Plus our users are not, as a rule, power/geek user that would understand even making subdirs in ~mail, so I don't know how this would have come to pass. Should this be? Or am I misunderstanding things? 2) Some people are consciously or unconsciously using the UWIMAP .mailboxlist subscription file as it is meant to be used, namely to *restrict* the folders shown. If/when I generated the Dovecot .subsbcriptions file by just doing an ls -1 of their mail directory, they will be surprised to see stuff not previously displayed....that they may very well not know they'd had. Murphy must be a terribly overworked deity...you'd think he'd take a rest now and then from maximizing entropy -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] mbox vs maildir
by Don Russell 10 Jul '07

10 Jul '07

I'm using Dovecot 1.0.1-12 on Linux/Fedora 7 along with sendmail and procmail all running on the same box mail is stored in mbox format It's a small system with a half dozen or so e-mail "accounts". Each with 40-60MB of messages in various folders. I keep seeing messages about how mbox is antiquated and anybody with more than 100 messages etc should not use mbox, but use maildir instead. I'm not entirely convinced.... there seem to be pros and cons for each. Is there a discussion somewhere that really highlights why one format is so much better than the other? The last time I tried to convert from mbox to maildir, things got pretty botched up, no data loss, but it wasn't pretty. :-) Can Dovecot handle mbox for some users and maildir for others? I'd like to try a conversion for one user... I'll probably create a new user, then have procmail copy (via ! action code) all mail for one user to that new user. Thank you

[Dovecot] secure pop for outside pop inside
by arjan 10 Jul '07

10 Jul '07

Hi all, I've a server with dovecot running in secure pop mode. For connections from the outside world, I don't want to enable pop. However, this machine is also the host for a vserver. In this vserver I have a webserver running the WebGUI Content Management System. One can add content via email. For this the cms has to be able to check a pop emailbox. The cms doesn't support secure pop. It's not nescessary either, because dovecot and cms are on the same machine. How can I configure Dovecot in such a way that I can enable pop just for one ip-adress and have secure pop for connections on another adress? Any help would be very much appreciated. Kind regards, Arjan

[Dovecot] Tbird-DC state problem
by Stewart Dean 09 Jul '07

09 Jul '07

A experienced sysadmin who's doing some guinea-pig use of DC just ran into the following situation: 1) He brings up SeaMonkey 2) About 30 minutes later, he's in the middle of some involved messaging, mistakenly hits the redX in the top right of the SeaMonkey window, knocking himself out of SeaMonkey. 3) He immediately reinvokes SeaMonkey, all appeared to be OK Viewed some e-mail and some web page references, tries to send a message and then the Send hung for a time with a message "Sending Authenticate Info"..after some minutes, a new E-mail window appeared stating the "Server reported a timeout". As far as the message, it was apparently sent successfully, and saved in the Sent folder successfully. 4) He calls me in. I look through the syslog logging. There is nothing in the syslog critical stuff...and everything in the maillog looks normal. 5) He starts another message, tries to save it to Drafts and that hangs 6) I look more closely at the maillog and see a lot of logins (one a minute in some cases, but all appear to have been cleanly executed) plus one bunch of disconnected messages with one disconnected in idle in the period when the write to the Drafts would have been hung. Could it be that DC was in the middle of clean up in the initial disconnect/reconnect and SeaMonkey came back in the middle of it and one or the other's state tables got messed up (or both of them)? Shutting out of SeaMonkey, waiting a minute and reconnecting seems to have gotten things working again. Any comments? Anything I should be looking for? OTOH, this is the first real problem I've seen in some person-months of testing..... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] PHP implementation of dovecotpw passwords
by Frank Church 09 Jul '07

09 Jul '07

I am looking for PHP functions that implement passwords that much the dovecotpw implementation. I downloaded one from PEAR, Crypt_HMAC, but the passwords it generates look nothing like the dovecotpw passwords, which could be my fault because I know nothing about the field. Is there a guide or some library that implements them to match dovecotpw?

[Dovecot] Your IMAP server has closed the connection.
by Dehnert James Sr 09 Jul '07

09 Jul '07

I'm getting a large number of ... "Your IMAP server has closed the connection. This may occur if you have left the connection idle for too long." errors. These are confusing my clients. Is there a way to set the timeout on the dovecot server to help avoid this?
