The bigger issue is going to be spamassassin and clamav and the size of the system will need to be based on the volume of mail you're going to transfer. We've pushed over 10,000 messages per day through sendmail on an old P2/400 with 256MB memory but it wasn't running any anti-virus or spam checking software. I've found that spamassassin and clamav tend to use a fair bit of memory. I would think that any modern CPU (i.e. P3/1Ghz or later which is actually 3-4 years old) with 1GB or more of ram will likely suffice. However, this is still going to be very dependent on how you use your system. If you have 50 users that love sending email to your own large mailing lists and all 50 subscribe to busy mailing lists, you may need to adjust accordingly. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
