> Does ISP mail server need to install mail virus scanner ??
You have to weight the arguments:
yes: centralized scanning allows easy update of virus signatures and
instant reaction to new problems
no: - centralized scanning uses server resources that are expensive/rare
and that are massive available at the workstations
- it makes DoS more likely to succeed (think of zip-bombs)
- it creates delays in mail transfer that may be massive (I know
of companies that had delays of up to 4 days)
I personally would not apply centralized scanning.
A compromise would be looking for several conditions in messages that
could be done fast without unpacking and scanning attachments.
