Iron Port experiences

[Patrick Sherrill <pa...@coconet.com>]

Has anyone any Iron Port experiences they could share?  We appear to be 
losing a larger account to Iron Port and am curious regarding their No FP 
claims.

One mans ham is another guys spam and viceversa. No service will provide 
a 100% fp/fn rate.

In fact, you'd be surprised how many of the commercial vendors are running 
a plain of somehow modified SA installation.

A fair comment Jeff. I wasn't aware that Iron Port gave back. I am
aware that some do, however, the original claim of 100% seems unlikely
at best. The larger the user base the larger the margin for false
positives/negatives?

Thanks for correcting me about the positives though, that is one I'd
overlooked; I'm sure there are many more.

Kind regards

Nigel

Not quite sure I understand your comments.  IronPort is one of many companies
that use open source technologies in their products, modifying, adding to, or
improving them in various, usually proprietary ways.  They leverage open source
and enhance it in their own products.  Many of these companies also find ways to
give back to the open source communities, for example by allowing their
employees to work on open source projects on company time.  For many it's a two
way street.

I'd personally be very dubious of anyone claiming no fp/fn's. I have
noted mails with Iron Port headers that have been tagged as (and
indeed were) spam. Admittedly, those headers could be forged easily
enough.

As has been said many times here, there are no perfect answers to spam
since any anti spam system needs something to tag off. If Iron Port
are making claims like that I'd be inclined to ask them to prove it.
They must have some metric they can demonstrate if they are making
such a claim.

Quite apart from that, if Iron Port were so perfect, there wouldn't be
a SpamAssassin list?

Just my 2 pence worth.

Kind regards

Nigel
