similar to: limit number of simultaneous lmtp deliveries ?

I just configured postfix' virtual_transport to point at my dovecot director, but am seeing occational problems like this: Aug 31 11:50:06 smtpgw postfix/lmtp[5339]: 69E2F5410D: to=<email at example.net>, relay=loadbalancers.example.net[192.168.42.17]:24, delay=0.15, delays=0.14/0.01/0/0, dsn=5.5.4, status=bounced (host loadbalancers.example.net[192.168.42.17] said: 501 5.5.4 Invalid

I enabled the trash plugin yesterday, adding "trash" to mail_plugins, and configuring the plugin setting "trash = /etc/dovecot/dovecot-trash.conf.ext". But I still see users with lots of files in INBOX.Trash getting bounced because of quota exceeded: postfix/lmtp[26273]:: C89F490061: to=<XXXXXXXXXXXXX at example.no>, relay=loadbalancers.example.net[192.168.42.15]:24,

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC

Hi *, we want to migrate our loadbalancers running CentOS 5.6 to new hardware and CentOS 6, however the (heartbeat-)ldirectord package seems to be hidden in the new LoadBalance repo in RHEL6. Any chance to get the RHEL SRPMs from this repo? Regards, Peter

Many ITSP are using loadbalancers, so if somebody registers on a sip peer with specific dns host, an incoming call may be received from a different ip and the host value in peer section doesnt match, so it will go to default context. For example Telekom or 1&1, biggest providers in Germany are using too many different addresses that its not practical to define them all (up to 50 hosts

FYI, we saw one panic on our director/lmtp-proxy yesterday. It's running dovecot v2.0.13, so it very well might have been fixed already.., but here it is anyway: Aug 31 11:33:31 loadbalancer1 dovecot:: lmtp(4119): Panic: file lmtp-proxy.c: line 370 (lmtp_proxy_output_timeout): assertion failed: (proxy->data_input->eof) Aug 31 11:33:31 loadbalancer1 dovecot:: lmtp(4119): Error: Raw

I'm having a server report a high load average when backing up Postgres database files to an external USB drive. This is driving my loadbalancers all out of kilter and causing a large volume of network monitor alerts. I have a 1TB USB drive plugged into a USB2 port that I use to back up the production drives (which are SCSI). It's working fine, but while doing backups (hourly) the

Dear All, Currently we are running a mail system for 10000 users each 2GB mailbox. At present we have 5 mail servers where users mailboxes are distributed almost uniformly. We have a HP SAN Storage (HP EVA 6400) where mailboxes are stored. We partition the storage into five vg and each is mounted on the 5 servers. We are using postfix and dovecot. The system was running fine but currently we

Thank you all for replies!!! Some missing infos... - As load balancer I'm using a pair of keepalived with simple setup and not the DNS - Load balancer algorithm is "Weighted Least-Connection" - About 20 domains and 3000 email - I'm monitoring my backend servers with poolmon - The backend servers are virtual machine (vmware) with datastore on "all flash" storage based

One of our backend pop/imap-server running dovecot v1.2.16 experienced some problems yesterday. It suddenly couldn't authenticate users anymore, flooding the logs with: pop3-login: Disconnected (auth failed, 1 attempts): user=<user1 at example.com>, method=PLAIN, rip=192.168.42.15, lip=192.168.42.28 The problem seemed to start with this log entry: Mar 29 18:57:21 popimap1 dovecot:

My existing pop3/imap environment is courier imap + vpopmail + qmail with MySQL backend. I'm looking at migrating this to Dovecot. Currently I have multiple instances of Courier bound to different loopback IPs (the IPs correspond with the virtual IPs on a server load balancer). When a user authenticates they don't have to specify a domain - if they don't, Courier will use a

I am running Dovecot IMAP on Linux, on a LizardFS storage cluster with Maildir storage. This has worked well for most of the accounts for several months. However in the last couple of weeks we are seeing increasing errors regarding corrupted index files. Some of the accounts affected are unable to retrieve messages due to timeouts. It appeared the problems were due to the accounts being accessed

Does anyone here on this list have experience with HA clustering? I'm previewing drbd as a potential tool, and wanted to know if anyone here has experiemented with it at all... How stable is it? Does the additional likelyhood of failure given the additional complexity actually get compensated by a better overall system? http://www.drbd.org/ Any feedback is welcome... -Ben --

I'm working the kinks of a new director based setup for the eventual migration away from courier. At this point, with everything basically working I'm trying to ensure that things are properly monitored and I've run into an issue. There doesn't appear to be a way to get dovecot to tell if it is (or is not) connected and properly synced with the other director servers in the ring

Hi, I'm new to this list and want your help. I'm the mail admin for some domains in Rio de Janeiro - Brazil. Today we have only one machine running dovecot (imap+pop3) with local mail. We are migrating to two virtual machines in kvm running in separate hosts. Then we have two main problems: - How to share mail files to both dovecots? We've been thinking about NFS using local indexes.
