BYE Connection limit reached for your IP address

Hi, Everyone

My customer's using Webmail (customer made webmail module using JavaMail API ) connect IMAP.

Rescently, I can see the following IMAP log.

-

2006/11/15 16:51:38 <E> <com.daou.winip.mail.manage.UserLoginManager> javax.mail.MessagingException: * BYE Connection limit reached

for your IP address;

nested exception is:

com.sun.mail.iap.ConnectionException: * BYE Connection limit reached for your IP address

-

As a result of this, login is very slow and IMAP connection is disconnected.

Anyone who experienced this, plz let me know how to solve this problem.

Mail versions are iMS5.2 patch2 and JES6.2

iPlanet Messaging Server 5.2 Patch 2 (built Jul 14 2004)

libimta.so 5.2 Patch 2 (built 19:30:12, Jul 14 2004)

SunOS mail 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-Enterprise

./imsimta version

Sun Java(tm) System Messaging Server 6.2-3.04 (built Jul 15 2005)

libimta.so 6.2-3.04 (built 01:43:03, Jul 15 2005)

SunOS fly 5.9 Generic_118558-06 sun4u sparc SUNW,Ultra-60

And I didn't change any IMAP setting.

Thanks

Hi,

Is the IMAP client connecting via an MMP to the store or connecting directly to the store?

By default the number of simultaneous IMAP connections to the *MMP* that are allowed from a single source IP address is restricted by the following rule in ImapProxyAService.cfg

default:ConnLimits 0.0.0.0|0.0.0.0:20

You can increase the limit from 20 to a larger number as appropriate which should stop the error message.

Regards,

Shane.

I'm pretty confused about what you're running, and where you're seeing the errors.

You say you're running both 5.2 and 6.2. Which one do you see errors with?

As Shane suggests, the error you've reported comes from MMP, as the basic iMAP server does not count number of simultaneous connections from any one source. MMP does.

What IMAP log to you see the error in?
