[TriLUG] linux antivirus solution

[Jason Tower]

i have two, maybe three clients who have networks consisting of windows
desktops and linux servers.  both are currently using individual antivirus
products at the desktop level.  i'd like to replace this with a centrally
managed, linux server based antivirus package (i.e. the linux server pulls
down the updates and distributes them to the workstations).  in addition,
i may be incorporating a mail gateway into these networks to handle
virus/spam duties before being handed off to the "real" mail server, so
anything that can be integrated into that role would be a plus, along with
real time scanning of any samba shares that exist on the servers.

can anyone provide "real world" experience with a product that fits this
profile?  thanks,

jason
