Portsentry and Sendmail

[stayler]

Hi Guys,

I've recently installed Portsentry and Log Sentry on my Firewall box,
Slackware 8.0 and 2.2.20, IPCHAINS.  I'd like the reports to be mailed
to me through my qmail server, which is on the LAN side of the
firewall.  The scripts in LogSentry have this ability, they use the
"mail" command, which I've found is in the mailx package.  I've
installed the package from the SlackCD and I found that to send the msg
to myself, via the mail server, I need sendmail installed. 

I am hessitant as I'm not familiar with Sendmail, its rather notorious
for complexity and security problems.  The version that comes with
Slack 8.0 is a little dated and I have DL'd the latest tarball from
sendmail.org.  The recommend PGP signing the tarball for safety and I
also got the .sig file, but to be honest I've had trouble figuring out
how to use GNUPG to PGP sign a file.

My question is in 2 parts.  Can sendmail be used without it becoming a
security hazard for remote delivery or are there alternatives that can
help.  I'd like something that can perform the smtp delivery without
opening a current or future security hole.

Second, how does one perform a PGP sign of a file?
