Hi all dont think ihave posted on this board before but hey there is a first time for everything.

ive setup a small network using red hat linux 7.2 < i think > as my e-mail server, and am also using it for people to browes the net. < im using sendmail >

all the other machines on the network vairy from windows 2000 pro to Xp.

as far as i know i donot have any virus protection on the mail server < i am lead to belive linux dosnt get affected by viruses, " i find this hard to belive" >.

my ISP is suposed to have some sort of protection and is ment to scan any messages i send or recive.

thats a description on what my network is setup as now for the problem at hand

most of the machines with in the network are reciveing e-mails from people or e-mail address they donot know, informing us that we tried to send them an e-mail which was infected with a virus. " it gives us a report of the virus and how many files were infected".
how is it that somone i donot know sends me a e-mal informing me that i sent them a e-mai which was infected with a virus if i didnt even have their address in my address book ???.

the other problem im having is that when we do get a virus in an e-mail its the workstation < windows machine, we using norton and AVG on the workstations > that picks up the virus.
how did the virus get past my ISP and my server ??

sorry if this e-mail is a bit long but very fustrated and running out of ideas to try

always x < any sugestions for visus proctection i can use please let me know >

Do a search on google for linux virus scanner
Your ISP probably only scans viruses on its own mail server rather than mail going between different mail servers.

My boss got a angry e-mail form someone getting blank e-mails from her. However, her computer scanned ok. The viruses will spoof the sending address. They probably got your name from someone elses address book. However, adding virus protection for your email server would be a good idea.

i think i have done a search for that already < didnt have any luck >
i was told to also do a search for CLAW ? < not luck either >
would like to use somthing somone has experiance with, im not int linux too much infact i only know a few commands, so would probably need a lot of help setting it up you know need somone to hold my hand. so if you have any ideas please.

thanx's

I believe you are thinking of CLAMAV.

There's a commercial product called ServerProtect by Trend available for linux servers.

While it is correct to continue in your direction and quest for email virus
protection on the system and server ends, you should know that email spoofing
seems to be quite popular. I work for real estate agency and when one of the
viruses spread across the Internet their email boxes take a pounding. Many
emails are along the links of "this email has been returned because it was found
to have a virus" many times this is their mail server that does the scanning and
rejecting.

One check to do is shut down the suspected infected system. For example turn it
of on the weekend while the user out of office. Do the infected emails warning
messages still continue to arrive during the weekend? I bet they might. I'd
suspect that system is not sending the emails and that users name is being
spoofed as the sender.

Spammers are such nice people hu?
