[Dovecot] scalability

[Eric Rostetter]

Quoting Jonathan Tripathy <jonnyt at abpni.co.uk>:

> How scalable is dovecot.

Very, but also it will vary by how you implement it (mbox or maildir,
local or remote disk, etc).

Yes, unless something else is slowing it down.

> This machine will also be running Postfix

If it is only running Postfix, it will probably be okay most of the time,
but if Postfix gets slammed it may slow down dovecot (actually the machine)
for a bit...

But if in addition to postfix it is doing (local) anti-virus and anti-spam
and such, it may not be sufficient, depending on setup.

In my experience, dovecot takes almost no resources, Postfix/sendmail
on take excessive resources occasionally when a spammer/hacker is hitting
the machine hard, and anti-spam/anti-virus programs can bring any system
to its knees...

> Your help is appreciated

To few details to give any definitive answers...
