[Dbmail] DBMail with MySQL and MyISAM tables

[Chris Nolan]

Hi all,

I've been using DBMail since version 1.0 with great success in an 
environment with about 10 users and about 20 GB of mail (stored 
permanently and pulled down via IMAP) all up.

I'm looking to deploy DBMail for a much larger installation (about 200 
users) with a minimum of mail each (retreived via POP3). Previously, 
I've used MySQL with InnoDB tables and have noticed that the setup blurb 
recommends InnoDB tables due to the amount of data to be stored. My 
experience with MyISAM indicates that it has no problems with large 
amounts of data as long as there aren't problems with OS-imposed size 
limitations, so I'm ignoring that part of the setup doc.

My question is whether any of the gentle readers of the list have 
deployed DBMail on MySQL using MyISAM tables. Given that MyISAM is 
extremely quick with INSERTs that occur at the end of the table and 
allows readers to continue while this is happening (and the maintanence 
run would happen when no one was using the thing), I'd be interested to 
see if it's worth using MyISAM, even if it is just for the space saving 
qualites.

Regards,

Chris
