Hundreds per year to host?
Author might want to dig around for a better host, you can get VM’s for under $10 a month which will have plenty of horsepower to handle personal email. Unless you’re dealing with thousands of messages a week I guess.
Only thing I miss from gmail is the spam filtering. Spamassassin + greylist do a pretty good job and eliminate about 95% of the junk, but google is good enough to get rid of 100% of it.
