Scott:
You mentioned
earlier that you do not think that WHITELIST HELO be something that should be
used too often. Could you please elaborate on this.
Why?
Can HELO be faked
easily?
We deal with a lot
with universities and government agencies as well as various clients with
military emails in our engineering company. [.edu, .gov,
.mil]
We had added .gov
as a WHITELIST.
WHITELIST HELO
.gov
of course recently
we found out something that caught my eyes. A junkmail got through with
the following HELO
something.gov.something
Can the HELO have
something like ENDSWITH so we can make sure this does not
happen.
This can also help
with big companies that one does not get spam from.
Microsoft.com,
ibm.com, oracle.com, etc.
the problem with
current HELO is if I do:
WHITELIST HELO
.microsoft.com
It will also
whitelist
.microsoft.comISNOT.biz
Of course this all
depends on your answer for why do you think this is not a good
idea.
Regards,
Kami
