[Dovecot] Dovecot / FreeBSD / Nfs mailstore / Index=memory
by Xavier Beaudouin 19 Mar '08

19 Mar '08

Hello, I have recently changed imap from Courier-imap to dovecot because of serial problems with courier-imap, I have being forced to do it very quickly... and without extensives tests. I have 3 mails servers (freebsd based) behind a load balancer and a nfs mailstore on a netapp. On my first tests I have setup the index into some nfs shared mount, but it seems that some imap clients are going mad when deleting files (mostly because they do open some new imap connection and the index was not clean) so I have changed index to memory. This has fixed one of my problems. Now I have some strange problems is that NFS activity passed from about... 5mbps to more than 70Mpbs... Is there any reasons about that ? OS: FreeBSD 6.2-p11 / x86 Dovecot : 1.0.13 (freebsd ports) Auth: ldap based Nfs mail spool : filer:/vol/vol0/mail /var/mailusers nfs rw,nfsv3,mntudp,bg,noatime,nolockd 0 0 Thanks, /Xavier

If you want to have postfix authentificate from the same Database as Dovecot, you need it, but otherwise I do not see no relation. Or do you installed some script, that checks mails for Groupware-related ones and act upon them immediately? I cannot help you with Postfix. For shared resources you'll need yet another, shared account or look into the ACL plugin. KOrganizer even supports imap URLs natively, I saw right now.

[Dovecot] Missing folders after converting from Courier imap to dovecot
by M. Bobkiewicz 19 Mar '08

19 Mar '08

Hi, I?ve searched around for my problem but couldn?t find a solution. My setup: Centos 5.1 with postfix 2.5.1 (from source) and dovecot 1.0.10 (from source). I?m coming from an old Trustix 2.2 box with postfix 2.2.x and Courier imap with Maildir format mailboxes. For testing I?ve copied over some of the mailboxes from the old machine. After logging in to the new machine with Thunderbird only the incoming and trash folders appear in the Thunderbird sidebar all the rest are not showing up. When you send an email the sent folder appears with all mails this account has sent from the old machine, same with drafts etc. Access a folder directly and it will appear with all it?s content. This is some kind of nasty if you have to do this for several hundred folders. I?ve tried to fix the problem by changing the namespace private parameter "prefix" to ".". Also tried to rename courierimapuiddb to dovecot-uidlist. Both tricks don?t work. Unfortunately I can?t find the mentioned courier-dovecot-migrate.pl, maybe this would help... Any help and suggestion would be welcome. Best regards, Mike

[Dovecot] problems with postfix->procmail->deliver
by Andy Greenwood 19 Mar '08

19 Mar '08

Hi all. I'm relatively new to Dovecot, but I really like what I'm seeing so far. I have one problem that I was hoping you could help me with though. I use Postfix for my mail server, then pass that on to procmail for filtering, and finally to deliver to put the mail in the appropriate Maildir folder. However, this isn't working. Postfix passes the mail to procmail correctly, but procmail is failing when it tries to call deliver. My system-wide procmailrc matches the lower one shown here: http://wiki.dovecot.org/procmail?highlight=%28procmail%29 which uses deliver. My personal ~/.procmailrc is of similar format :0 * ^List-id:.<beginners.perl.org> #.perl/ | $DELIVER -m perl :0 * ^Sender:.owner.freebsd-\/[^@]+@FreeBSD.ORG { LISTNAME=${MATCH} :0 * LISTNAME??^\/[^@]+ # .freebsd-${MATCH}/ | $DELIVER -m freebsd-${MATCH} } :0 * ^Sender:.owner-cvs-all@freebsd.org #.cvs-all/ | $DELIVER -m cvs-all :0 * ^Delivered-To: greenwood.andy+combackup(a)gmail.com #.work/ | $DELIVER -m work :0 #$HOME/Maildir/ | $DELIVER However, my procmail logs show this error message for every message that comes through: Fatal: destination user parameter (-d user) not given I can see that the variable $DELIVER doesn't use the -d parameter, but I'm not sure on how I would specify the value in a multi-user system. I know I could just use deliver directly from Postfix, but I really want to use the filtering capabilities of procmail. If you need any additional information, just let me know. Thanks in advance for any help you can give, and big thanks for this great piece of software! Andy Greenwood

[Dovecot] max connects per host?

Seems redundant that every piece of software accepting connections should duplicate the functionality of a firewall. /Johan Yes. In some cases it could be good choice. But in _general_ it's not. It's about functionality of a mail server, isn't so? And how your users will know, what they reached limits and it's not case of broken connection/firewall/network related problems and so on?

[Dovecot] max connects per host?
by subscriber＠viliar.net.ru 19 Mar '08

19 Mar '08

Hi everyone! I want to manage mail server resource part (like it can CGP) and with it I have one question. Is any way to limit overall max simultaneous connections to imap/pop3 server from one(each) host, except use iptables/ipfw and so on? Like a patch to dovecot or, maybe, it can be released in future versions? I know about mail_max_userip_connections in dovecot 1.1 but it can't limit hosts this way. Thank you.

[Dovecot] Invalid quota rule using "backend"
by Laurento Frittella 19 Mar '08

19 Mar '08

Using a quota rule like "quota_rule = *:backend=1073741824S" (I'm testing it statically but the value is on LDAP) I receive an an error: Fatal: IMAP(...): Quota root QUOTA: Invalid rule: *:backend=1073741824S Accordingly with the wiki page http://wiki.dovecot.org/Quota/New "Backend-specific configuration currently is used only with Maildir++ quota backend. It means you can have the quota in Maildir++ format (e.g. "10000000S")." so I think it should work. What's wrong? Cheers, Laurento

[Dovecot] xexec and dovecot 1.1
by subscriber＠viliar.net.ru 19 Mar '08

19 Mar '08

I'll test very interesting plugin xexec. It seems very nice and can be used in many things. It's compiled perfect with dovecot 1.0, but certanly not with dovecot 1.1. It's stopped with next error: In file included from cmd-xexec.c:30: xexec.h:8: error: expected specifier-qualifier-list before 'array_t' cmd-xexec.c: In function 'cmd_xexec': cmd-xexec.c:134: error: 'array_t' undeclared (first use in this function) cmd-xexec.c:134: error: (Each undeclared identifier is reported only once cmd-xexec.c:134: error: for each function it appears in.) cmd-xexec.c:134: error: expected ';' before 'union' I found, that in dovecot 1.1 has been changed some of functions of array init and so on. I'm not programmer :(, just a system admin., but first of all have to check it and trying to resolve by myself. According examples in ../../lib/array.h I removed array_t and this code is seems ok: xexec.h struct xexec { ARRAY_DEFINE(setups, struct xexec_setups *); }; and also here: cmd-xexec.c ARRAY_DEFINE(command, char *); After, errors cames with cmd-xexec.c: In function 'cmd_xexec': cmd-xexec.c:144: warning: passing argument 4 of 'client_read_args' from incompatible pointer type cmd-xexec.c:159: warning: assignment from incompatible pointer type cmd-xexec.c:180: warning: implicit declaration of function 'ARRAY_CREATE' cmd-xexec.c:180: error: expected expression before 'char' As I understand, it is because of (from changelog) Replaced ARRAY_CREATE() macro with [ipt]_array_init() macros. The macro has no side effects so it might as well be lowercased. I have look at the array.h, but can't find appropriate function in list of array_create,i_array_init,p_array_init,t_array_init. Should I just forget about it, until someone adapts code for dovecot 1.1, or maybe it no so complex, as looks? Thank you.
