p3scan

NAME

SYNOPSIS

p3scan [options]

DESCRIPTION

It implements a centralized email scanning point, transparently inspecting messages fetched by internal network hosts from servers "in the wild" (the Internet) for viruses, worms, trojans, spam and potentially dangerous attachments. Since HTML email can be used by spammers to validate the recipient address (via Web Bugs) p3scan can also provide HTML stripping by using the associated p3pmail (or other) program.

It can also inspect outgoing SMTP messages for virus's.

p3scan can help you in protecting your "Other OS" LAN especially if used synergically with a firewall and other proxy servers.

  Configuration file
/etc/p3scan/p3scan.mail
  Symlink to the email message templates sent to client in event
  a virus is found. You can create a symlink, or copy a language
  file p3scan-??.mail for any language provided. If you translate
  a mail file into your own language, please consider contributing
  it to the project so that others may enjoy your work.
/etc/p3scan/p3scan-??.mail
/etc/p3scan/p3scan-??-??.mail
  Email templates for specific languages.
/etc/p3scan/p3scan.footer (optional)
  This file is used to add the virus definition info from your scanner
  to an smtp message. It will only be added as a footer if the message
  is not signed cryptographically and is only a text message.
  It is used in conjunction with the "footer" option in the
  following fashion:

  1) If file does not exist and "footer" is defined:
     No footer information will added to outgoing messages, but the p3scan
     version and scanner info will be added to the header.

  2) If file exists but blank and "footer" is defined:
     P3Scan version/host info and scanner info will be added to end of
     message and header.

  3) If file contains information and "footer" is defined:
     All lines of this file will be added to the end of the smtp message and
     then p3scan version/host info and scanner info will be appended.

  4) If file does not exist and "footer" is not defined:
     P3Scan will only insert p3scan version info into the header.
