Antivirus solution

[Allister Gearon]

Hi all,
 can anybody recommend an antivirus solution for scanning incoming email at
least (outgoing emails would be a bonus) with a SuSE based (8.2) Cyrus-IMAP
mailserver.
Versions are;
cyrus - imapd   2.1.12
cyrus - sasl2   2.1.12
fetchmail    6.2.1
db    4.0.14
postfix    2.0.6
    Thanks for your help
