[Dovecot] Acl Groups
by Dimitrios Karapiperis 26 Nov '09

Hi all! I have a corpus of virtual users ( user1(a)domain.tld , user2(a)domain.tld, user3(a)domain.tld,..., usern(a)domain.tld ... ) authenticated against Active Directory. Is it possible to group some users (virtual) and give appropriate ACLs on a shared imap public folder using an ACL vfile? thanks in advance Dimitrios

[Dovecot] Dovecot hosts in France?
by Anatoly IVANOV 26 Nov '09

26 Nov '09

Hi, * Would someone recommend web hosts in France using Dovecot, please? I'd prefer to outsource the server management to someone else (although I could install and run my own Dovecot server). I need the server to be located physically in a French datacenter for legal reasons. Sorry if I'm a bit off-topic. Not a technical question. Thanks in advance.

[Dovecot] 1.2.7: recs[i]->uid < rec-> uid
by Edgar Fuß 26 Nov '09

26 Nov '09

I'm getting this Panic with some users on dovecot-1.2.7: Panic: file maildir-uidlist.c: line 1242 (maildir_uidlist_records_drop_expunges): assertion failed: (recs[i]- >uid < rec-> uid) There's another dovecot-1.2.3 running on identical hardware accessing the same NFS mail storage without problems.

[Dovecot] restrictions on folder length?
by Brett Dikeman 25 Nov '09

25 Nov '09

Greetings all, After migrating a few dozen people to our departmental mailserver, we've run into a problem with one user who makes extensive use of folders and nesting them. I've seen as many as 8 levels. The longest resulting folder name is 113 characters, which results in a total path length of 137 characters (/var/spool/mail/******). Their old mail server handled this fine, but dovecot is choking on it; imapsync reports "invalid mailbox name", and he gets the same error clicking on the mailboxes in Thunderbird (they seem to have been created, despite the error messages.) Mail was imported over using imapsync, and did so flawlessly for all the other accounts. Are we running up against a soft (configuration file) or hard (source) limit? Or is this a bug? Thanks! Brett

[Dovecot] expire plugin + --exec-mail in 1.2.6 version
by Nikita Koshikov 25 Nov '09

25 Nov '09

Hello list, After upgrade to dovecot version 1.2.6 I have noticed some quota malfunctions(users become often overquota). Looking at logs closely I have found that quota value resets to general dovecot-config( quota = maildir:Mailbox quota quota_rule = *:storage=500M quota_rule2 = Trash:storage=10%% ), after dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh command. The problem that some users have their own quotas stored in ldap. For example, user sr(a)domain.com have maildirsize before running expire-tool(1G value from ldap): # head -2 /data/mail/domain.com/sr/data/maildirsize 10485760000S 836423205 8285 Then I run expire-tool with mail_debug enabled: # /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh Info: Loading modules from directory: /usr/lib/dovecot/imap Info: Module loaded:

[Dovecot] new to dovecot
by Lars Nielsen 25 Nov '09

25 Nov '09

Hi there, I have installed debian with exim4 postgresql 8.3 and dovecot 1.0.15. I have the mail delivery part done, so when i send mail it gets delivered in ~/MailDir/ I have tried to authenticate via passwd and postgresql but with no luck. I have read a lot on google but i cannot get dovecot to give me the mails via pop3. Is there a tutorial somewhere i have missed? so far i have messed up my config like this : # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/errors.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 pop3_uidl_format: %08Xu%08Xv auth default: verbose: yes passdb: driver: pam userdb: driver: passwd regards Lars Nielsen
