You can quite confortably fit SA and a full SMTP + IMAP stack in less than 1 GB. My (admittedly low volume) mail server is currently sitting at 340 MB of used memory and is running: - Postfix - Dovecot - Spamassassin - spamass-milter - opendkim milter - Various python mail sorting / organizing scripts - openssh server - BIND9 (master DNS server) - Radicale (DAV server) - Weave (Firefox sync server) - Nginx (reverse proxy) I haven't found the need for any sort of AV scanner. Some SA rules that reject messages with executable attachments have been more than adequate for me. --Sean
