[Dovecot] valid folder name
by Jan-Frode Myklebust 05 Jun '13

05 Jun '13

We have a quite large user base, with lots of bad folder names because the mail folders was earlier accessible outside of dovecot. Now we're running dsync conversions from maildir to mdbox for all users, but are struggelig a bit with dsync not liking invalid folder names. Before we convert a user we try to determine if the folder names are valid, but we don't have a very good regexp for validating it. Maybe someone else knows a way to verify (and fix?) folder names that are invalid. The rules I know is: - name doesn't start with '.' or '~' (after the initial '.') - name doesn't end with '.' - the name doesn't contain '..' - the name is valid mUTF7 So, any regexp gurus that can distill those rules down to something usable? -jf -- Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems. -jwz

Hello Christian, I tried what you suggested by adding "REFERALS off" to /etc/ldap/ldap.conf and restarting slapd and dovecot, but the error persists.

[Dovecot] Administrative mailbox deletions
by Alan Brown 04 Jun '13

04 Jun '13

I'm in the process of nuking a bunch of dead mailboxes after they've been migrated to other servers - but the accounts have been kept. A simple shell script takes care of most of it, BUT.... (there's always a "but" isn't there?) One user has named all his mailboxes with leading hyphens. ie: -foo -bar -bazz and "doveadm mailbox delete" doesn't like it. Does anyone have the magic sauce needed to escape the - character? Thanks in advance Alan

a login tohuw [myPassword] returns "NO [AUTHENTICATIONFAILED] Authentication failed."

That does work. Thanks. Alan

[Dovecot] Imap Server as storage backend for dovecot
by Micha Krause 04 Jun '13

04 Jun '13

Hi, I remember reading about the possibility to configure a namespace to point to another imap server (not dovecot) and use it as a backend for storing mails. However, I could not find any documentation about this, so Im not sure if I remember correctly. Micha Krause

[Dovecot] recursive mail_location?
by Eric Abrahamsen 04 Jun '13

04 Jun '13

Forgive what may be a newby question, but I'm trying to get a new setup working, and there are many different things confusing me. I'm trying for a gnus + dovecot + mbsync arrangement, with mbsync writing to maildirs, and gnus reading from those dirs with a dovecot invocation. Fairly standard, I think. I have multiple email accounts I'm trying to sync, all of them gmail. My problem is that mbsync creates one maildir structure for each mailbox in each account. So I end up with: ~/mail ├── acc1 │ ├── INBOX │ │ ├── cur │ │ ├── new │ │ └── tmp │ └── OTHERBOX │ ├── cur │ ├── new │ └── tmp └── acc2 ├── INBOX │ ├── cur │ ├── new │ └── tmp └── OTHERBOX ├── cur ├── new └── tmp And so on, for many accounts, and many mailboxes. I believe there's something I can configure in mbsync to collapse this a little, but there's still going to be quite a bit of nesting. Gnus, meanwhile, is meant to invoke dovecot with the "-o mail_location" switch, and as far as I can tell that needs to be pointed at a maildir structure, which means I would need a separate gnus server for each mailbox in each account. Does anyone have a recommended way of handling this? Is it possible to either "flatten" the structure further, or somehow tell dovecot to recurse into directories? I don't mind having a separate gnus server for each mail account, but I'd hate to have to do one per mailbox. I'm only just getting started and haven't invested myself in any particular setup, so if the answer is "you're doing it all wrong", I would love to hear that. Thanks! Eric
