[Dovecot] Mobile phone client - first access
by Ron Leach 20 Aug '10

20 Aug '10

Ladies and gentlemen, good morning! With my first post to the list, may I begin by saying how impressed I have been by Dovecot's performance on our Debian server. We've configured it to run with Exim and Fetchmail, using Dovecot to manage professional and domestic emails for a small home office, serving a number of Windows and Linux clients both on the internal network and, when working overseas, via SSH tunnels back to the Debian server. Dovecot's performance has been, simply, rock-solid; a very impressive piece of work by Timo and all those supporting him. My ordinary mobile phone - a Sony Ericsson C510 - includes an email client with IMAP capability (and none, TLS, or SSL encryption). Configured to access our server across the mobile carrier's network, the results surprised me; they were not what I expected. The first surprise was, it worked. More seriously, the messages it retrieved were not what I expected; the phone received around 58 messages, but from the 'inbox', the 'junk' box, and a couple from a 'project' box. I had expected to only retrieve the messages that were in the 'inbox'. How does Dovecot 'decide' what messages to give the phone client? [I think I may have the wrong 'mental model' of what should have happened, and would appreciate being put right.] Is it possible to configure Dovecot to only serve specific boxes? The mobile phone client is extremely simple - it does not have the facility to 'browse' the folders, it only has an inbox, sentbox, etc; I have wondered whether there might be a 'jar' email client that is richer, and which might help - I will look for something anyway. But I was impressed that my mobile phone could check our home and office email while offsite; if I can get that working it will save having to fire up the laptop at each opportunity. Thanks very much for reading this far, and, also, thanks everyone who takes the time to contribute to the list, regards, Ron

[Dovecot] Director mailserver health monitoring script
by Brad Davidson 20 Aug '10

20 Aug '10

Timo et al; The last bit of functionality that the Dovecot director is missing compared to our existing load balancers is mailserver health monitoring. As I understand it, if a mailserver goes down, Dovecot does not take any action to route connections around the offline node, and will keep trying to proxy clients to it. Since we're hoping to cut over to Directors soon, but don't want to lose any functionality, I've hacked up a script that: * Polls the local director for a list of mailservers * Performs health checks against a list of ports on each mailserver * Disables or enables mailservers (by altering the vhost count) as necessary I've published the script on github in hopes that it might be useful to others: http://github.com/brandond/poolmon/ Maybe someday Dovecot will do something like this internally and I won't need the script any more, but for now I'm pretty happy with it. -Brad

[Dovecot] Disable APOP challenge in POP3 login greeting
by Brad Davidson 19 Aug '10

19 Aug '10

Timo, It looks like Dovecot 2.0 appends an APOP challenge to the POP3 greeting even if APOP is not an enabled auth mechanism. Is there any way to disable this? We don't support APOP, and the challenge includes the private hostname of the server, which we'd rather not have in the banner. It looks like get_apop_challenge in 1.2 returns NULL if APOP isn't supported, which causes auth_client_ready to omit the banner... but I see no such check (in fact, no way for get_apop_challenge to return NULL) in 2.0, even though pop3_client_send_greeting tests for it. Thanks, -Brad

[Dovecot] mailbox utilities
by Terry 19 Aug '10

Hello, Are there any utilities that will spit out statistics about some mailboxes I have on my server? For example, how many messages are in each mailbox? They appear to be in mbox format (default?). Thanks!

[Dovecot] dovecot 1.2 and quota_rules from AD
by Christian Lyra 19 Aug '10

19 Aug '10

Hi I´m trying to figure how to proper configure postfix+dovecot to enforce quotas from a AD (ldap). I´m using the following configuration: dovecot.conf: ... protocol lda { mail_plugins = quota .. } auth default { passdb ldap { args = /etc/dovecot/dovecot-ldap-pass.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } ... } plugin { quota = maildir:User quota #quota_rule = *:storage=2M // tried with and without this line } dovecot-ldap.conf: ... user_attrs = sAMAccountName=mail=maildir:/var/vmail/%$/Maildir, quotaMail=quota_rule=*:storage=%$ user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u))) pass_attrs = sAMAaccountName=user,userPassword=password pass_filter = (&(objectClass=person)(sAMAaccountName=%u)) Quotas are set by the quotaMail in AD. And here is the log: Aug 9 11:41:37 vm29 dovecot: auth(default): master in: USER#0111#011testeti(a)teste.mydomain#011service=deliver Aug 9 11:41:37 vm29 dovecot: auth(default): ldap(testeti(a)teste.mydomain): user search: base=dc=mydomain scope=subtree filter=(&(objectClass=person)(| (mail=testeti@teste.mydomain)(sAMAccountName=testeti@teste.mydomain))) fields=sAMAccountName,quotaMail Aug 9 11:41:37 vm29 dovecot: auth(default): ldap(testeti(a)teste.mydomain): result: sAMAccountName(mail=maildir:/var/vmail/%$/Maildir)=maildir:/var/vmail/testeti/Maildir Aug 9 11:41:37 vm29 dovecot: auth(default): master out: USER#0111#011testeti@teste.mydomain#011mail=maildir:/var/vmail/testeti/Maildir Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): auth input: mail=maildir:/var/vmail/testeti/Maildir Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): Quota root: name=User quota backend=maildir args= Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): maildir: data=/var/vmail/testeti/Maildir Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): maildir++: root=/var/vmail/testeti/Maildir, index=, control=, inbox=/var/vmail/testeti/Maildir Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): Namespace : Using permissions from /var/vmail/testeti/Maildir: mode=0700 gid=-1 Aug 9 11:41:37 vm29 dovecot: deliver(testeti(a)teste.mydomain): msgid=<201008091142.53089.lyra(a)pop-pr.rnp.br>: saved mail to INBOX There´s no quota_rule in logs... uncomenting the line quota_rule = *:storage=2M I got quota, bu only this static one, and not per-user. What I´m doing wrong? Btw... with static configuration the maildirsize file is created, but without static configuration it´s not (well.. no quota_rule...). thanks in advance, -- Christian Lyra POP-PR - RNP

Dear All, According to my setup i can not call |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda from my /var/qmail/control/defaultdelivery file, Instead making a perl file which will call the same for delivery of mails. If i put the following code in my mail.pl |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda then it throws error in running file from command line. Warning: Use of "-f" without parentheses is ambiguous at /var/qmail/bin/mail.pl line 2. syntax error at /var/qmail/bin/mail.pl line 2, near "|" Execution of /var/qmail/bin/mail.pl aborted due to compilation errors. content of mail.pl #!/usr/bin/perl |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda Any help will be useful for me.
