I don’t guess I ever thought about moving mailroot, but that is a really good idea.  Here’s an article that tells how to do it just so no one has to go looking..

Just to add my $0.04 worth:

 

By the time you ask what's the minimum, it's usually too late and not enough. The SMTP queue drive should, as a general rule, not get below 10% free space.  The way the product works, every smtp message is accepted then acted upon. What that means to you is that SMTP messages are going to hit the disk hard. This indicates that you want to separate that I/O from the rest of the server where possible.  That would mean that you'd typically place this directory on a dedicated set of spindles and the smallest drive size you'll likely find these days is a 72GB drive.  If your average message is ~100KB, then you have approximately 72GB/(100KB-10%) of space before you would even want to consider that your drive should stop.  That's a lot of a messages for most corporate implementations and could easily translate into several days worth of mail at those numbers.

 

Wouldn't you want your mail system to stop sending at some point like that? So that you go find the issue and resolve it?

 

Honestly, I think the better questions to ask are going to be along the lines of what is the typical formula for figuring out drive performance and sizing of Exchange server drives for the various i/o types? That will give you the better idea of what you can and should not get away with on those disks if you need to make changes.  If you don't make changes, at least you'll know the areas to be aware of.

 

My thoughts anyway.

It depends mostly on how busy is the server.

Of course.

Hi,

 

I have 2 emails server in 2 different locations.

All the sudden emails are not coming from one server to the other, I found out that smtp queue folder was in  a hard drive that was running out of space.

 

Do you guys know what is the minimum amount of HD space needed for the smtp to work?

 

Also, if the hard drive gets full will that stop the queue from delivering the emails?

 

 

Thanks

 

Rezuma
