+E-MailRelay is a simple SMTP proxy and store-and-forward message transfer agent
+(MTA). When running as a proxy all e-mail messages can be passed through a
+user-defined program, such as a spam filter, which can drop, re-address or edit
+messages as they pass through. When running as a store-and-forward MTA incoming
+messages are stored in a local spool directory, and then forwarded to the next
+SMTP server on request.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
