Hi,
It depends on the amount of users and mail you expect. If you are looking at a large site (50,000 users or more), I would recommend:
- At least 512 megs of memory
- Lots of disk space (60 GB would be a good start that would let you grow for a while)
- A 1GHZ+ processor
As for software and modules I recommend:
- Latest MySQL (3.23.40+)
- Digest::MD5 and MIME::Base64 perl modules installed
- qmail (not required, but I really like it and it can handle lots of mail)
Let me know if you have any other questions,
Cheers,
Alex
