[Dovecot] Multiple attempts to get mail delivered
by Gerard Seibert 24 Jul '06

24 Jul '06

FreeBSD 6.1 STABLE I am using a basic MBOX mail setup. I have noticed that when the MBOX size starts to grow, say 35-30M or more, Dovecot will not always deliver the mail via POP on the first attempt. In fact, in some cases it takes four or five attempts before it will actually deliver the mail. Is there some setting that I should be changing? There does not appear to be any error written to the log file. Ciao! -- Gerard Seibert gerard(a)seibercom.net Take diplomacy out of a war and the thing would fall flat in a week. Will Rogers

[Dovecot] [PATCH] Substitution of dots to ", dc=" in variable expansions
by Antonio Kanouras 24 Jul '06

24 Jul '06

Hi list, my ldap directory uses DNs like this: uid=solist,ou=People,dc=solistland,dc=net,ou=Virtuals but I only could use something like uid=solist,ou=People,dc=solistland.net,ou=Virtuals with dovecot, which obviously isn't what the dcObject object class was meant to present. I've written a small function for var-expand.c which introduces a new modifier for string variable expansions, %D (arbitrarily chosen), which substitutes dots to ",dc=". You might want to include that in dovecot's code base, after bringing it up to dovecot standards of course. :-) Example of use: base = ou=People,dc=%Dd,ou=Virtuals Warning: I'm a beginner in C and could only understand so much of dovecot's code, so this patch is a hack at best. That said, I tested it with more than 10k logins and can say it works for me. :-D Cheers, Antonio

[Dovecot] Maildir++ quota - how to handle a full mailbox
by Joseph W. Breu 24 Jul '06

24 Jul '06

Hello all, We are using Horde/IMP and we are having problems deleting messages from accounts where the user is very close to going over quota. My test environment includes: Horde 3 IMP 4.1.2 dovecot 1.0rc2 postfix maildrop I created a user and set the quota at 13MB. I then sent a 10MB file to the user - which was received. However, when I attempt to move the message from the INBOX to Trash, I get a Quota Exceeded error. Is this more of an IMP error than a dovecot quirk? Is the message size credited back to the quota after the message has been removed from the INBOX? Is there any way to change the order that the qouta usage is applied? -- Thanks, --------------------------------------------------------- Joseph W.

[Dovecot] MySQL table for use with dict et quota
by mikael 24 Jul '06

24 Jul '06

In your "http://wiki.dovecot.org/Quota/Dict" documentation, the table to create is : create table quota ( path varchar(255) not null primary key, username varchar(255) not null, current integer ); "path" field is the primary key. But when i see the SELECT queries, "path" is always used ('quota/storage') and username too. I don't understand... If "path" is the primary key, it must be unique in quota table ? Perhaps the table would be like this : create table quota ( path varchar(255) not null, username varchar(255) not null, current integer, primary key (path, username) ); No ? I start to have a headache... :D 2 days with dovecot quota, and no fully working results :'( Please, help me :) -- Mikaël

[Dovecot] POP does not seem to be working
by Gerard 23 Jul '06

23 Jul '06

OK, I am brand new to this so please bear with me. I have an FreeBSD 6.1 STABLE system. Postfix is installed with qpopper. The mailboxes are standard mbox format. I just installed Dovecot. At some point I want to update to a mdir format, etc., but quite frankly I do not know how to go about that. In any case, I shut down qpopper and started Dovecot. I modified the Dovecot.conf file SSL settings (turned them off) since I do not have the files it needs built yet. Anyway, when using a mail client on another PC on my network, although it makes a connection, no mail is ever downloaded. Ther is mail in the folders however. Obviously I am doing something really wrong, but I am not sure what. I would sure appreciate any assistance available. The only information I have is in the 'log' file which shows the a pop3-login, the user name, method=PLAIN, and two numeric addresses. Thanks! -- Gerard Seibert gerard(a)seibercom.net

[Dovecot] help with authentication - cpanel
by allan hardy 22 Jul '06

22 Jul '06

I am trying to install dovecot as a second pop3 service in my RH9 system. It is a Cpanel based system using Courier for primary IP By primary I mean all the other domains use courier on xxx.xxx.xxx.21 port 110 I have a domain with special pop3 needs that is dedicated to xxx.xxx.xxx.22 port 110 The two mail systems are installed, I can tell via telenet that dovecot is listening and responding on the desired IP and port Cpanel is the tool being used by all domains to create mail accounts and hence setting the 'policy' for the mailboxes, userdb and passdb information. I am trying to make dovecot use those files and can't get past authentication. What I guess I don't know is the encryption type being used by Cpanel Any help appreciated.!!!! What Cpanel appears to do for authentication is use a passwd and shadow file for each domain, placed as follows: /home/accountname/etc/domainname/passwd holds the list of mail accounts names /home/accountname/etc/domain/shadow holds the passwords This is the message log from a telnet session on local machine: dovecot: Jul 22 13:45:27 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.179.22 rip=xxx.xxx.179.22 resp=AGFsbGFuAHRlc3Q= dovecot: Jul 22 13:45:27 Info: auth(default): shadow(allan,xxx.xxx.179.22): password mismatch dovecot: Jul 22 13:45:29 Info: auth(default): client out: FAIL 1 user=allan dovecot: Jul 22 13:45:36 Info: pop3-login: Aborted login: user=<allan>, method=PLAIN, rip=xxx.xxx.179.22, lip=xxx.xxx.179.22, secured ~ This was in the shadow file: ---Shadow file entry allan:$1$V0lG6T6P$eNQoX3J3N5RJNxT5yH8gz1::::::: These are my relevant (At least I think they are relevant) dovecot.conf settings: disable_plaintext_auth = no ssl_disable = yes auth default { mechanisms = plain login anonymous passdb shadow { /home/xxxxxx/etc/xxxxx.com/shadow } userdb passwd-file { # Path for passwd-file args = /home/xxxxxxx/etc/xxxxx.com/passwd } --PAM is commented out As a side note, I tried to see if I could tell from the courier setup how it was authenticating. The courier/etc/pop3d file was set POP3AUTH="" And there was a note "To advertise the SASL capability, per RFC 2449, uncomment the POP3AUTH variable" So it this may indicate sasl is being used, what ever that means
