postlogin script
by Michael Fox 14 Dec '16

14 Dec '16

I'm using the postlogin service, following the examples in the wiki. But I can't find any documentation on the behavior (what's allowed/not allowed) of the script-login binary. So, some questions: Question 1: The examples show the following at the end of the post-login.sh script: exec "$@" My understanding is that this would exec each of the command line arguments to the post-login.sh script. But, there are no arguments sent to the post-login.sh script in the examples. So what is this line supposed to do? Question 2: One of the examples shows exporting some environmental variables, followed by the above exec line: export MAIL=maildir:/tmp/test export USERDB_KEYS="$USERDB_KEYS mail" exec "$@" Now, I'm really confused. Can someone explain step-by-step why this does anything at all? Question 3: I'd like to be able to pass some information to the post-login.sh script, such as the service (%s), as a positional parameter. For example: executable = script-login /path/post-login.sh %Ls Or even more explicitly: executable = script-login /path/post-login.sh imap But it appears that the script-login binary is expecting only script names to be passed to it so that it can handle more than one script. Is there a way to pass arguments to the different scripts? Thanks, Michael

mailboxes and capitalisation
by Thorsten Hater 14 Dec '16

14 Dec '16

Dear all, I have set up a series of special-use mailboxes in the default namespace differing by capitalisation of the names, mainly to capture multiple mailboxes with autoexpunge namespace inbox { ... mailbox Trash { auto = no autoexpunge = 30d special_use = \Trash } mailbox trash { auto = no autoexpunge = 30d special_use = \Trash } ... } However, doveconf -n reports only one mailbox, namely the second (lowercase t) and autoexpunge does not trigger for the first one (capital T). Removing the special use flag has no influence. namespace inbox { inbox = yes list = children location = ... mailbox trash { auto = subscribe special_use = \Trash } ... prefix = INBOX. separator = . subscriptions = yes type = private } Is this the intended behaviour? The example 15-mailboxes.conf seems to indicate otherwise and I would prefer the ability to set autoexpunge for both Trash and trash. (dovecot 2.2.26 built from source on Debian 8.0) Best regards, Thorsten

Simple way to get mailbox size by folder.
by Vijay Sarvepalli 13 Dec '16

13 Dec '16

Is there a simple way to get each mailbox size using dovecot's IMAP interface? The GETQUOTAROOT and GETQUOTA seems to work with the full maildir size and not the individual folders. I am finding a simple way for the webmail client to show usage of each folder. Thanks Vijay

Heloo, please I need "replicate" dovecot / dsync. Prerequisite: doveadm user '*' [Root @ joe ~] # doveadm user '' ' Error: User listing Returned failure Fatal: user listing failed It probably does not work because I have: userdb{ args = cache_key =% u quota_template quota_rule = = *: backend = q% driver = vpopmail } The manual is written: iterate_query = SELECT email as user FROM mail_user But does not specify how to connect to MySQL database if vpopmail How to do it ?
