[Ross Davis - Data Anywhere]

I am about to take over the hosting of a website and want know if my 2 mail
servers are going to be able to handle the volume.

They are two P166's with 64M ram and plenty of disk space.  There are about
2000 emails per day going through the existing mail server.  My servers will
be on a dedicated 10MB connection.

How may mails a day should I be able to handle?

Thanks in advance
