I doubt anybody meant that, even if it was said.

As part of yr evaluation, please read the u/g in the section for SMTP
Security. There are several techniques within Imail for defending against
unauthorized relaying and spam.
(I hope to have a first cut this weekend on a external, front-end defense
machine for Imail based on FreeBSD and postfix that will do RBL, reverse
lookups, RegEx filtering on headers, and anti-relaying before forwarding
msgs to Imail. That ought to take care of everybody's concerns about some
of those features being missing from Imail. The software is open source
(free) and an old P200 with 32 or 64 megs of RAM and 3 or 4 gigs of disk
ought to be sufficient.)
