I'm using MailScanner to run SpamAssassin on a FreeBSD box here, between our firewall's inbound SMTP proxy and our Lotus Notes cluster, doing exactly this. As I have it, it does (1), (2), and (3) above. Here's the .mc file I feed to make to create my sendmail.cf: : divert(0)dnl : VERSIONID(`Mike Andrews 06Dec2002 1550 CST')dnl : OSTYPE(bsd4.4)dnl : DOMAIN(generic)dnl : FEATURE(access_db, `hash -T<TMPF> -o /etc/mail/access')dnl : FEATURE(blacklist_recipients)dnl : FEATURE(local_lmtp)dnl : FEATURE(accept_unresolvable_domains)dnl : FEATURE(`use_cw_file')dnl : define(`confCW_FILE', `-o /etc/mail/sendmail.cw')dnl : define(`confMAX_MIME_HEADER_LENGTH', `1024/1024')dnl was 256/128 : define(`confNO_RCPT_ACTION', `add-to-undisclosed')dnl : define(`confPRIVACY_FLAGS', `authwarnings,noexpn,novrfy')dnl : define(`MAIL_HUB', `relay:[10.36.36.33]')dnl : define(`SMART_HOST', `relay:[10.36.36.33]')dnl suggested by Rob MacGregor : define(`LOCAL_RELAY', `relay:[10.36.36.33]')dnl suggested by Rob MacGregor : MASQUERADE_AS(`ODOT.ORG')dnl : MASQUERADE_DOMAIN(`okladot.state.ok.us')dnl : FEATURE(`masquerade_entire_domain')dnl : MAILER(local)dnl : MAILER(smtp)dnl The firewall is set up to feed all inbound mail to this box; there are two sendmail processes running on the box: one to put the incoming mail in the "in" mail directory, and one to take processed mail out of the "out" mail directory. The bridge between them is MailScanner, which reads mail from "in", runs SpamAssassin and various virus scanners on that mail, quarantines files with names which match certain regular expressions (.exe, .bat, .com, .cmd, .scr, .pif, and so on), replaces quarantined files with attachments explaining what was quarantined, and then puts the processed mail in "out". I am absolutely satisfied with this setup. -- Mike Andrews [EMAIL PROTECTED] Tired old sysadmin since 1964 ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
