Hi all, I'm sure my issues are a result of misconfiguration, but I'm hoping someone can point me in the right direction. I'm getting pressure to move us back to GroupWise, which I desperately want to avoid :-/ We're running dovecot 1.2.9 on Ubuntu 10.4 LTS+postfix. The server is a VM with 1 vCPU and 4GB of RAM. We serve about 10,000 users with anywhere from 500-1000 logged in

Hi I'm using Dovecot version 1:1.2.15-7 installed on Debian Squeeze via apt-get.. I have this error in the logs. /var/log/mail.log.1:2490:Jan 19 12:02:55 mail dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=<user at example.com>, method=PLAIN, rip=127.0.0.1, secured I never changed this from the default 10. When I googled

Good day, I am currently setting up/debugging a webmailer-only setup using Roundcube (latest version) with Dovecot (2.3.20, latest as of now). Generally speaking the setup performs OK, I wrote a JMeter Roundcube script to test the Roundcube. This includes actions like listing mails and fetching them. I am hitting a somehow dubious limit of 600 req/s though. (This includes all kinds of HTTP calls

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present? Thanks,

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

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

Hi System debian 8.11 and dovecot-2.2.36.4 My webmail is roundcube with imapproxy. I have one problem.

Hi, mail_max_userip_connections is only enforced at the backend level. The setting has no effect on proxy. If you want to force the limit then you can only do it in the backend.

What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: > ps auxwww | grep "imap " | wc 237 3080 22400

We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users.

I just migrated from courier-imap to dovecot and dovecot is a lot faster. My only client is webmail on the same server as dovecot. Max ~10 users. Should I still run imapproxy like I did with courier? Does dovecot periodically empty the trash folder like courier does? I reduced the number of processes courier was running to save RAM and improve performance. Are there any performance tweaks I

Hi, has anyone seen this issue before as I have not. I'm a long time dovecot user and I don't see anything in the config that should cause this. The mail.log gets hit a lot of times with this same log message: dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections) I have noted that it is more evident when I try to mass delete many

Hi, we are actually deploying a new IMAP-Server, targeting dovecot 2.1.17. Unfortunately, our tests with imaptest did not succeed, were ending in core dumps. We did this test: ./imaptest host=example.com port=143 user=strack pass=secret disconnect_quit no_pipelining mbox=dovecot-crlf That's what we get in dovecot's log: Sep 10 11:17:04 imap-login: Info: Login: user=<strack>,

Hi, Trying to keep abusive/buggy IMAP clients at bay on a number of Dovecot proxy servers, I've reconfigured them to use "mail_max_userip_connections = 50" in the "protocol imap" section, followed by restarting Dovecot. Yet, I'm still seeing 160+ established connections from a single IP address for the same email account. Am I missing anything? # 2.2.27

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net.
