similar to: mail_max_userip_connections=10

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

I frequently see this from my iPhone/iPad IMAP users: Oct 24 21:30:55 server dovecot: imap-login: Login: user=<user>, ...

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

Thanks for the reply and suggestion Robert. I have now set mail_max_userip_connections to 400 in 20-imap.conf to see if it makes any difference. Late yesterday the customer tested from his office, an older IOS 9 tablet and he had IMAP working in a matter of minutes, so is certainly an newer software version by Apple issue.

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

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

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 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, 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,

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

v1.1 has now: # Maximum number of connections allowed for a user. The limits are enforced # separately for IMAP and POP3 connections, so you can move this setting # inside protocol {} to have separate settings for them. NOTE: The user names # are compared case-sensitively, so make sure your userdb returns usernames # always using the same casing so users can't bypass this limit!

I have been haunted by the following error message or months, that we see using Thunderbird. Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialogue to reduce the number of cached connections. If I change my location, via a VPN, the error message goes away and I can connect. I have

You can usually see from doveadm who or logs if your router/whatever is doing NAT. Which would be the reason why 500 connections wouldn't be enough.

I'm working to get Dovecot 2.0.13 working along with qmail, Vpopmail and Squirrelmail on a Debian 6.0.2 system, Dovecot compiled, not from a package. Vpopmail has a widely known assigned user/group ID of 89 and is the owner of all the mail folders. Regardless of value of first_valid_uid (1, 89, other), Dovecot denies Squirrelmail connection, saying it can't allow access to UID 89.

Is it possible to limit the imap/pop connections per user in dovecot? If so i couldnt find the option to do that. Thanks! -- Jordan Tardif DreamHost
