Ok. Didn't know that. I know that it's supposed to handle LDAP dying,

The code only deals with temporary ldap disconnections. If a ldap
connection goes stale the code will try to reconnect every 2 seconds,
and will try this 5 times. So

Just put a max quota on your users accounts, then they *must* delete
some old e-mails. If you don't use quota, people will never delete, as
they just don't realize they need some space.
still, the database size is increasing average 2GB per day. btw, do u happen
to know the maximum size mysql can handle? with the rate this is going, its
gonna be 2TB at the end of next year..
run the following query:
select userid,curmail_size from dbmail_users order by curmail_size desc

It only recovers empty space and re-orders (like a defrag). If your
usage is increasing, the best way is to remove emails. Maybe you need to

he! are those innodb table spaces? Been reading about them, but haven't
used them yet..
But isn't that a MyISAM database?

No. It's a innodb table space, where the innodb engine keeps separate
files per table. The shared table space is then mainly used for
housekeeping.
For all you myisam users: starting dbmail-2.1.x myisam is deprecated!
Better start getting used to innodb.

Thanks, that's clear. I just didn't know, that InnoDB can store tables
in separate files..

Hi all!
After 1-2 months testing dbmail I have installed it on our main mail
server. Now everything is ALMOST fine, but some questions still not
resolved. The first question about dbmail-util.
If we run dbmail-util -arf our database starts performing
OPTIMIZE TABLE procedure.
Everything Ok,

- please answer.
I'm open to suggestions and ideas here. I've been having this very same
problem.

Big RDBMS (Sybase, Oracle) have advanced table partitioning
Ah, that'll help.
Looks like mysql-5 will have what we need:

I see it's on the TODO list for postgresql

Merge tables are mainly based for having two identical tables then
'merging' them together with a third. I am guessing that he wants RAID
chucks in the 'create table' statement. Also, InnoDB has built in
functionality to create new files and roll over...
