[Dovecot] Saving archive copy of all mail sent/received w/Dovecot+Postfix?
by Andrew M 12 Dec '11

12 Dec '11

I'm running Dovecot 2.0.15 and Postfix 2.7.7 with postfix handing off to Dovecot's LDA. I am hosting multiple virtual domains with multiple users and everything is working. I would now like to create a permanent archive of all sent/received mail with each virtual user's mail saved to its own sent file and received file. This needs to be independent of the user's regular Maildir store since he can't delete or modify the permanent archive. Any suggestions on how to best accomplish this either via postfix or dovecot? Postfix has in main.cf virtual_transport = dovecot and in master.cf dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/libexec/dovecot /dovecot-lda -d ${recipient} -f ${sender} dovecot uses this: [root@xxx andrew]# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.14-103.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no mail_location = maildir:/home/vmail/%d/%n/Maildir mbox_write_locks = fcntl passdb { args = scheme=plain username_format=%u /etc/postfix/passwd driver = passwd-file } protocols = imap lmtp service auth { inet_listener { port = 12345 } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/pki/tls/certs/xxx.com.crt ssl_key = </etc/pki/tls/private/xxx.com.key userdb { args = username_format=%u uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static } Thanks, Andrew

[Dovecot] mail_max_userip_connections=10
by Tom Clark 12 Dec '11

12 Dec '11

Hi, A couple of questions rather than a problem for once! We've got our Dovecot server running smoothly now apart from our MD. He's having problems with mail_max_userip_connections. He has 3 (Phone/Laptop/Tablet) items that all connect to the server at about the same time. Which means he's frequently running over the max_userip_connections. My questions are: Is there anyway of whitelisting an IP so that it can ignore mail_max_userip_connections=10? What should we set mail_max_userip_connections too realistically? 10 seems a bit low? Thanks Tom

[Dovecot] question regarding postfixadmin
by oni-neko＠gmx.net 12 Dec '11

12 Dec '11

Hello! I hope someone here is already using postfixadmin with dovecot and can help me out =) the install-readme for postfixadmin mentions, that the mail-home should be set to default_mail_env = maildir:/var/mail/vmail/%u/ but my dovecot is already installed and working with another config, namely mail_location = maildir:/var/dovecotmail/%n/Maildir. Do i have to change this, or is postfixadmin able to read this or can i set this value in postfixadmin somewhere? i´d rather avoid moving all mailfolders around just because of that, and unfortunately the paths don´t really lend themself to an easy solution via symlink ^_^ thanks for any replies best regards sil -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Documentation clarifiction on mmap_disable
by Marcio Merlone 12 Dec '11

12 Dec '11

Greetings, On http://wiki.dovecot.org/MainConfig I read: "mmap_disable = no Don't use mmap() at all. This is required if you store indexes to shared filesystems (NFS or clustered filesystem). " Does that mean: 1. mmap is required when using NFS or 2. it is required to don't use mmap at all when using NFS? Sorry if this is obvious. Best regards. -- *Marcio Merlone*

[Dovecot] database failover
by Nick Edwards 12 Dec '11

12 Dec '11

Trying to get dovecot to _only_ use local copy of database, only querying another database server (same database, just replicated) if local copy is not responding, I have google fu'd a bit and found my only answer in so far as dovecot did this once upon as time, but it was only due to a dovecot bug, that has since been fixed, is that so? The wiki shows no information of failover, just load sharing, or is it an undocumented feature, or can dovecot not do failover, if not, can it be made so? Trying to cut down on network traffic, postfix does this nicely, I thought dovecot did too.
