[Dovecot] IMAP subfolders and MBOX format

2009-05-14 Thread Frank Bonnet
Hello folks I have a problem related to the mbox format I think First we use MBOX format with Dovecot 1.14 A user's here need to create some subfolders in his Imap space. Due to the use of MBOX format this is impossible from thunderbird as you cannot creat a directory in a file :-) So to help

[Dovecot] Unable to subscribe to newly created subfolders under public mailboxes with acl plugin enabled

2009-05-14 Thread Max Ivanov
I've group namespace and b2b mailbox under it. I'm unable to subscribe to it and deliver emails there. Here is my problem: if I create subfolder (lets name it subf) under b2b mailbox I'm unable to subscribe to it until acl plugin is enabled. Even if I put dovecot-acl file in .b2b.subf folder with

[Dovecot] Possibly dumb questions about DC and user/system limits

2009-05-14 Thread Stewart Dean
Because of user access growth, the number of processes associated with IMAP has increased and I thought to change some of the configured parms. dovecot -n yields: # 1.1.14: /usr/local/etc/dovecot.conf # OS: AIX 1 005A928C4C00 listen: *:143 ssl_listen: *:993 disable_plaintext_auth: no
