Hello All,

First time poster many time reader.

Since Friday I am getting flooded with e-mails infected with Sober-I
virus. They all seem to be from one source and they are relaying through
our secondary Mail Server (Our ISP supplies the secondary).

It seems the one user can bring our server to its knees and the inbound
queue just backs up.
As a remedy I have to reject e-mails from the secondary server using the
access file in sendmail.

Does anyone know of a better way to block this without having to block
our secondary mail server?
Is it a performance tuning issue? We are using MailScanner 4.35.11 and
Sophos AV, not SAVI, and SA 3.0.1.

The machine is running Redhat 8.0 and is a XEON 2.4GHz CPU with 1GB RAM.
Connection is only a T1.

Thanks for any assistance,

Alan Cragg
