64MB would be a little low, but you might get the basics (SMTP + POP/IMAP, 
command-line and file-based management). Things like spamassassin and 
clamav would have to be skipped though; those take a lot of memory.

I've been running my setup on a Linode virtual server for a few years now. 
It's the cheapest they offer ($20/month), and was 512MB until they doubled 
everyone's memory recently. ClamAV and Spamassassin used huge percentages 
of that 512MB (e.g. 20% for one clamav process). I'm also running MySQL and 
Apache (mostly for Postfix Admin, which is a PHP app), which take the next-
biggest amount of memory.

But I'd really recommend aiming higher than 64MB. I'd recommend at least 
256MB, and I'm sure you can do better than that for a reasonable price.
