Amavis with clam antivirus seems like a very good fit for the existing Exim base for mail.msu.edu. On a second note, developing a web interface for end users to select from public blacklists to use for filtering their incoming mail would also be a nice feature, or at the very least, implementing something like a SpamAssassin option for the user to allow for tagging of emails before downloading/reading if they choose. I've setup multiple servers with this type of configuration, and end users haven't seen a single virus in their inbox for a very long time, and spam loads are reduced by 95%+. On average, 50-75% of incoming email has proven to be spam for the systems that I admin. I expect MSU has similar (if not higher) stats. While these solutions are not commercial products, neither is Exim, or the OS running under it (generally). I know it's not as simple as saying "this works, lets plug it in and use it", but there are some very effective solutions out there that don't cost a too much. That's my $0.02 on the subject anyhow. :) -Russell Rich Wiggins wrote: > E-mails laden with viruses, especially fraudulent software patches, > are for sure very common these days. > > The Computer Laboratory mail team is exploring a range of anti-spam > and anti-virus alternatives.
