I had completely forgotten I had added such a feature :) See what it logs with attached patch. Hello, I have found the problem. Is not a dovecot issue. The problem (if this is a problem) is that our ldap is behind a load balancer. This load balancer has a timeout of 3600s for ldap connections. If there is a connection with more than 3600s without activity, the load balancer close it, and this is the reason of the message. Now I'm trying to find why dovecot has a ldap connection with inactivity. One question, does auth process use more than one ldap connection? If it uses a pool is more reasonable, because we have auth cache enabled and now he have low activity, so it could be that a connection last more than 1 hour with activity, isn't it? -- Angel L.

Re: [Dovecot] On IMAP vhost login, only Username being used
Recapping: I'm working to set up Dovecot 2.0.13 along with some
additional software (qmail, vpopmail, squirrelmail). It's working fine
with squirrelmail now, but trying to connect over SSL with a Thunderbird
variant and using IMAP, authentication fails because Dovecot is trying to
match only the front part of the name (the user part), ignoring the domain
name part of what it's being sent. So, instead of seeking to match
virtual user:
joe_blow@some_domain.com
...it's trying to match:
joe_blow
...and failing, since joe_blow is not a system user but is a virtual host
user. With Squirrelmail, connecting from localhost via non-SSL IMAP, the
match is handled correctly, no problem. I've run the runtbird.sh script
but no light was shed on this by the resulting output, all it said was
that authentication was failing.
Has anyone else encountered this problem? Any suggestions on how to fix
it or where to look for additional info? Thanks kindly.
--hobie
> I tried the runtbird.sh script, hoping for more info - all it did was
show that auth is failing. I don't understand why Dovecot is separating
the username from the domain name, and trying to match only on the
username. Seems like there must be a config setting that affects this
and that I'm overlooking. Thanks ahead for any help with this.

Re: [Dovecot] Dovecot 2.0.13 How to use POP3 order

You'll need to add "O" fields to dovecot-uidlist where the numbers are sorted in the order you want the mails to show up. For example: 1 O2 Pfoo :mailfile1 2 O1 Pbar :mailfile2 Now message with IMAP UID 2 is shown first in POP3 UIDL (with POP3 UIDL "bar") and the message with IMAP UID 1 is shown second in POP3 UIDL (with POP3 UIDL "foo"). But if you're only migrating from another POP3 server, this doesn't matter. It was added only to fix the situation when IMAP UID order doesn't match POP3 UIDL order and the user has been using both IMAP and POP3. So if you simply want POP3 UIDLs to be in wanted order, just put them in the right order to dovecot-uidlist: 1 Pbar :mailfile2 2 Pfoo :mailfile1 http://no1.wiki2.dovecot.org/MailboxFormat/Maildir explains dovecot-uidlist more, and you can also look at http://www.dovecot.org/tools/courier-dovecot-migrate.pl as an example.
[Dovecot] Dovecot 2.0.13 How to use POP3 order
I saw a few commits for 2.0.13 that added MAIL_FETCH_POP3_ORDER, but I haven't been able to find any information on how to use it. I'm migrating from a Merak mail server into dovecot and all the email can be copied directly into a Maildir/cur directory. The filenames are just the timestamps. When I check with dovecot pop3, they seem to be randomly ordered. I'm hoping this provides a solution where it will look at the file list or stat order. If this isn't possible, can someone tell me how I can change the order in which dovecot lists mails in a UIDL in POP3? Thanks, Nick Celebic

So you have a quota of 10GB on the mailbox, but the Trash has an
additional space of 1GB for the abilioty to delete mails.
