Increasing mail_max_userip_connections and sys resources
by Nikolaos Milas 15 Jan '16

15 Jan '16

In our low-traffic server we have always kept the default value for IMAP mail_max_userip_connections (10). The server has been working fine! (Thank you Timo for this!) However, recently we have been having: Maximum number of connections from user+IP exceeded errors both for IMAP and webmail users. Thus, we have now changed the value to 100. The questions: 1.Might this lead to overloading the server? 2. Could another dovecot setting prevent the above setting from being applied (e.g. due to connections exhaustion), i.e. should we also change other setting(s)? 3. What should we take into account when deciding the value for mail_max_userip_connections? 4. How can we set a different value to this directive for webmail connections (coming from 127.0.0.1, ::1)? The config follows for your reference (I've only changed the real domain name). Thanks in advance for your help.

doveadm/dsync/imapc and foldernames including a "%"
by Peer Heinlein 14 Jan '16

14 Jan '16

We're using doveadm/dsync/imapc to migrate accounts from Courier to Dovecot 2.2.20. On the source-server some user have folder names including a "%" in their name. Looks like doveadm isn't able to handle that folder names. I always stops with: dsync(testtest): Error: Failed to access mailbox INBOX.Test%TEST: Mailbox does not exist, or must be subscribed to.

Hi. I have Dovecot + Postfix + MySQL.

Hi,according to this page: http://wiki2.dovecot.org/SSL/SNIClientSupport (last change 2013) I would like to know if this limitation is still valid. # dovecot --version2.0.9 I am trying to configure Android default email client and I am not able at all to use TLS.

autoexpunge problems
by Olaf Hopp 12 Jan '16

12 Jan '16

Hello, I tried to use the new autoexpunge for my Trash folders I had in 15-mailboxes.conf mailbox Trash { special_use = \Trash auto = subscribe } (dovecot -n of the original config is below) and added just the line autoexpunge = 1h Just a short period on my test system. But it failed. In the log I see Dec 18 10:54:07 irams2 dovecot: imap(ms2test): Error: Failed to autoexpunge mailbox 'Trash': Invalid mailbox name 'Trash': Missing namespace prefix 'INBOX.' But in 10-mail.conf I have namespace inbox { prefix = INBOX. separator = . inbox = yes } So I changed the line "mailbox Trash" to "mailbox INBOX.Trash". I now have mailbox INBOX.Trash { special_use = \Trash auto = subscribe autoexpunge = 1h } Now it seems to work (Trash is emptied, log file is fine) but in the mail client I see two Trash folders. Once the normal one below INBOX and another one also called Trash which is under a new created folder named INBOX below the original INBOX Thus I have INBOX INBOX.Trash INBOX.INBOX.Trash autoexpunge seems to work, but this is not what I like to offer to my users.

Problems with doveadm backup in a dovecot director environment
by Tobi 12 Jan '16

12 Jan '16

Hi list I have configured my dovecot(s) in a frontend-backend setup using the director feature of dovecot. Works like charm, but I'm currently unable to use doveadm backup to "sync" the mailbox to a dovecot system which is not within director_mail_servers settings Before I added the director feature I could fire a simple doveadm backup -u myuser(a)mydomain.tld tcps:otherserver.mydomain.tld:2424 After activating the director the command above fails as the connection is always tried to be established to one of the servers specified in director_mail_servers. Is it possible to use doveadm backup towards a server which is not in director_mail_servers? I tried with the -o option of doveadm to override several settings like host or director_mail_servers but no success: the command still tries to connect to an ip from director_mail_servers and not to the destination given as parameter to the command. Is there anyway to achieve that? Thanks a lot for any help tobi
