[Dovecot] Statistics

HI list, According to this: http://webcache.googleusercontent.com/search?q=cache:QMGLz9SVNdwJ:www.dovec… << # Use statistics to automatically distribute heavy users to different servers * v1.2 can export very detailed statistics via plugin >> I can't find this "detailed statistics" plugin, I only found this: http://www.dovecot.org/patches/2.0/stats-plugin.c But it only seems to add a "stats" IMAP command. Please can somebody confirm or give me a link to this plugin ? I really need to identify "heavy" users,so this plugin may be really usefull for me. Thanks a lot, Pierre

[Dovecot] Fixed mailbox id?
by Dieter Knopf 28 Sep '10

28 Sep '10

Hello, I have many Sieve rules and searching for a way to "track" renamings/moving of mailboxes (folders) on my IMAP server. Is there a unique ID for every folder available? I don't think there, i found no ID inside my folders :( If not, it think i need to create a ID-file for every folder and after that i can track the folders and update the rules =) Thanks

[Dovecot] AntiSpam Plugin

28 Sep '10

Hi, I don't remember how to turn off debugging for AntiSpam plugin ... it still writes it's debug output to /var/log/debug.log ... But everything works fine now - so it can be turned off since it just wastes my Memory ... Thanks & Regards

[Dovecot] Need more info on new fsync switch
by interfaSys sàrl 27 Sep '10

27 Sep '10

Hello, I wanted to improve performance by disabling fsync where I can, but the example in the Wiki is outdated http://wiki2.dovecot.org/MailLocation/LocalDisk # Enable for IMAP/POP3 fsync_disable = yes protocol lda { # Disable for LDA/LMTP fsync_disable = no } Can that simply be replaced by the default config which is mail_fsync = optimized Or should it be replaced by # Enable for IMAP/POP3 mail_fsync = never protocol lda { # Disable for LDA/LMTP mail_fsync = optimized } Cheers, Olivier

[Dovecot] Meaning of mail_max_userip_connections?
by Harald Strack 27 Sep '10

27 Sep '10

Hi, I set mail_max_userip_connections in our IMAP configuration to mail_max_userip_connections = 10 to allow users 10 parallel connections. It seems that this also limits the amount of parallel connections from one IP but different users?! Our users mostly accessing the IMAP server by a webmailer or proxies. Thus, all users (>10000) come from only 5 different IP. However, I got a lot of complaints about denied connections after setting mail_max_userip_connections = 10. Am I right with the meaning of this parameter? Thanks in advance Harry
