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 shoul...

thunderbird just crashed, and I've never seen this before. Any idea what happened? this was in the dovecot log: 2010-12-02 13:06:40 imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=<pbc>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured 2010-12-02 13:06:40 imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=<pbc>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured 2010-12-02 13:06:40 imap-login: Info...

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 (&gt...

As such, we would expect for it to be possible to override mail_max_userip_connections under the "protocol imap" section, with a passwdfile userdb looking something like this: example:{CRYPT}x:1011:1011::/mail/example::userdb_protocol/imap/mail_max_userip_connections=100 The userdb returns the expected fields in the correct format (according to the documentation): #...

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...

I can confirm setting mail_max_userip_connections from database in userdb query *does not* work at all. User can still open multiple connection above the limit, seems like it has no effect. I thoroughly checked DB response and it contains proper field name/value. I am using dovecot 2.2.31. Also, I have mail_max_userip_connections set globally...

Hello. Is still true that mail_max_userip_connections cannot be overriden in userdb query? Want lower global and raise for some logins. https://www.dovecot.org/pipermail/dovecot/2017-July/108520.html -- Arkadiusz Mi?kiewicz, arekm / ( maven.pl | pld-linux.org )

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 messages. Any ideas of how to diagnose this issue? The dovecot -n follows: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.1-rscloud x86_64 Ubuntu 10.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot...

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 overloadin...

In a previous thread Subject: Re: iPhone/iPad IMAP connection bursts causes user+IP exceeded I reported the behaviour of MacOSX/iOS IMAP readers whereby it would use up all available connections (up to the mail_max_userip_connections setting) for mailbox searches, then log them all out, then repeat the cycle with another batch of mailbox searches, until all mailboxes were scanned. However, login/logout log counts don't square up. I would observe (for a particular user+ip) mail_max_userip_connections login entries, followe...

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?

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.

Hi, 1) Why dovecot -n doesn't display default values? At least it didn't display mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 if I had set ONLY mail_max_userip_connections (to be =10) 2) "Maximum number of connections from user+IP exceeded (mail_max_userip_connections): " Could it be enhanced to actually log what the lim...

Hi Sometimes, I hit mail_max_userip_connections limit. As far as I know I'm the only person that does, but I would like to find out why before someone else hits the limit. Is there a command available that can list the connections per IP? I'd like to find out which client is causing this. Or do you have a better suggestion? Should I...

I think returning mail_max_userip_connections from userdb works.

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.
