Re: [mailop] Forwarded spam, was Microsoft JMRP

[Otto J. Makela]

Just on a side note, I wish hotmail.com (a part of Microsoft) would get
their act together and stop putting their own internal 10.*.*.* network IP
addresses in the Subject when reporting spam originating from our clients.
It makes writing procmail rules to detect already resolved cases a pain.

​Technically speaking there is no reason - would be more of a learning /
training curve then anything for customers if we were to disable the
ability to setup forwards.

Why can't your customers pull their mail from the forwarding site?

These are my opinions.  I hate spam.

Hi John,

>From what I have been able to determine (and that's on the basis that what
I deem spam is the same as customers marking it as spam) is as follows:

Actual Spam: 30%
Legitimate Emails: 50%
Unsure: 20%

As an example a customer on one of our shared hosting servers is forwarding
email from his domain to an account at Hotmail, which then is marked as
spam sometimes.
The contents of the emails we receive from JMRP suggests that it's not spam
at all.

We do run ALL of our shared web hosting infrastructure through an anti-spam
cluster to help weed out the junk, but no system is perfect.

In reality I would love nothing more then to disable forwarding
functionality from our side, but since almost every other host appears to
offers that type of system we may potentially shoot ourselves in the foot
by doing so.

On another note, perhaps what is needed for systems that forward is an
actual confirmation from the destination of the forwarder before it's
go-live to say they agree to accept forwarded email from the email address
x...@.com

It won't do much to stop legitimate spam being forwarded through to them
from anybody abusing it, but at least you would then be able to rule out
somebody malicious setting up forwarders to different addresses just to get
either the account holder or the web host in trouble.

Cheers.

So is the stuff they're marking actually spam, or real mail?

These days, anyone who forwards mail without a lot of spam filtering
first is shooting themselves in the foot.  Yes, it's unfair, it's too
much work, blah blah blah, but that's life.

Any sort of "this is forwarded so don't blame us" is a non-starter,
since spammers can put on the same tags you can.

R's,
John
