Exchange Mailboxes

[Fuzzz]

The badmail folder contains messages that can't be delivered, like NDR's with a non-existant recipient (mostly spammessages). I had this folder filling up and clogging my mailserver once...

The way around this is to have your Exchange check wether or not a recipient exists when receiving mail, rather than accept the mail, check for the recipient and when te recipient does not exist, send a NDR (wich, in the case of spam, can't be delivered because the sender address was spoofed).

If there are any messages in the badmail folder, just delete them, they can't be delivered anyway...

Where do i find that folder??

[Fuzzz]

I think it's somewhere in C:\Program Files\Exchsrvr (maybe under MDBDATA)...
I've moved mine to another drive, so i can't check anymore...

If you use search in Explorer and search for 'badmail' you should find it.

Assuming its in the default location, look in:

c:\Program Files\Exchsrvr\Mailroot\vsi 1

may well do this over the weekend on my test server. Can i use the eseutil on another server that is not exchange?

Yes should work, I think it is in the bin folder under exchsvr. Should just be sble to copy it and the datastore to a different box for defrag/compress.

As a rule when sizing the volumes to be used for an exchange database you need at least as much free space as that used by your database and log files.

If your exchange database used space is 40Gb then you need 80Gb of total diskspace.

The reason for this is so that your exchange maintenance can work properly by making a copy of the database during the maintenance cycle.

If you get to the point where your free space is less than your used space the database never compresses properly and it starts to grow rapidly.
Space created by deleted items never gets compressed.

Once this happens an offline defrag and compress using eseutil becomes essential.

If you want to keep your database small keep it on a volume with plenty of space and it will keep itself healthy.

Where possible I keep the logs on one volume and the databases on another.
Even better keep the databases on an expandable array.
