Free fprot software for linux

Mikrop is a small, easy to install program for mail servers to scan incoming email. Its currently integrated only with postfix MTA.
MAXSIZE = maximum size of incoming messages including the attachment files. this parameter is important and you should set it to a high value if you are not sure.
TMPMAILDIR = temporary directory for files being scanned.
VIRCMD = your antivirus program (you can add parameters here)
VIRNFOUND = The string that is going to be looked for in the antivirus programs output. Ex: Fprot outputs "No viruses or suspicious files/boot sectors were found."
and i took the No viruses part in my default mikrop configuration file.
v1.2 - > if youre using another virus scanner that doesnt give any output like uvscan than delete/comment this line on config.h
INFDIR = directory for infected mailboxes.
PROCMAIL = if you use procmail as mail filtering utility you should define it here. e-mails will be passed to this program if theyre clean.
SENDMAIL = Currently this parameter is used for sending a warning message to
the person who sent infected file.
USERMBOXES = if you dont use procmail define your spool directory. clean e-mails will be appended to the file in this directory/USERLOGIN.
MSG = the message alert that warns the target user
VIRADMIN = the contact user, the string which is going to be appended at each warning message.

- Easy to install and configure.
Enhancements:
- Shell script added for automatic update of f-prot viruslist.
- Undefining VIRNFOUND feature added to config.h for use of
