Hi,

Form our experience with DBMAIL the imap deamon tends to get very sluggish when there are large loads on it and mail boxes are large. We decided to move away from DBMAIL and move back to a flat file exim solution with a super fast san device we had 3 times as much data as you have in your Mail database.

Hope this helps. It was also a fearly painless migration from DBMAIL back to exim.

Hello,

I'm an administrator of a popular website. I run a free email system. I use Roundcube as Webclient. The mail works on DBMAIL system. Unfortunately, I encountered a problem.

The email's been running for two months now. 30 000 users registered during the period and mailboxes consume 30 GB space. But, suddenly, there is a problem with Roundcube connecting to DBMAIL IMAP.

The messages are being opened very slow when connected to Roundcube (3-4 seconds/message). The comprehensive analysis has been done, but the problem hasn't been found. Server load is 0. Server logs show that Roundcube takes information from DBMAIL base and IMAP very quickly, but we don't know what it does for the next 3-4 seconds.

I tried to connect Roundcube to the other mail system, that's not usings DBMAIL, and everything worked fine, even though that system is more loaded. Also, I tried to connect to DBMAIL using SquirrelMail 1.5 and everything worked fine. We tried other WebMail clients and everything worked fine as well.

So my conclusion would be, that the problem is a DBMAIL and Roundcube compatibility issue.

Maybe someone has any ideas on solving the problem? I need to get this fixed in a couple of days and I don't want to go on a diffrent WebMail client.

I will appreciate any help and advices!
