hmmm. i don't know about everyone else, but 100% of my users use SMTP
AUTH if they want to send email out.
How do you verify that?
How can you know they do not input their email address else where?
hmmm, that wasn't my point.
I know. I just wanted to present the other possible scenarios.
if somebody wants to send an email to a
domain _not_ on my system, then they have to authenticate.
You mean _from_ a domain...
That sounds reasonable because you are Host of domains (web sites), not an ISP
with single domain for all myriad of users.
Your customers can use their ISP account for the sending from other domains. I
would not expect a Host to provide that.
However, note that AccuSpam is a forwarder for a lot of customer email, so it
sends from domains not on Pair's (our Host) system. We must hope AccuSpam is
the final SPF enabled anti-spam in the recipient's chain! SenderKeys would not
have this potential problem with forwarding.
If they want
to send email out of something else, that is 1) their perrogative and 2)
their own worry.
Sometimes easy to say until your biggest customer complains...
I think the thing is, I am not going to automatically go in there and
set up SPF for my customers so they can't send email from anywhere else.
It is when they call complaining about getting 1,000 NDRs each day I
will explain to them 1) what is going on and 2) what can be done.
Yes in that case they understand the risk-benefit analysis well, so you are
probably okay. Also your customers are probably reasonably intelligient/savvy
given they are using highly customized Host services (per what you write below).
If SPF become formally accepted and is mainstream enough, I would likely
make a decision to inform all my customers about that.
I support that.
i run about 900 domains. i am just small potatoes, and i only try to
make things better "on average" as best I can. if somebody complains, i
give it personal attention and make it happen.
Well that is not insignificant sample IMHO. If that is 300+ customers, you
might get some reasonable feedback about SPF in future.
AccuSpam knows a little bit more (than what you could gleem for content
analysis), because it correlates not only votes on domains, but correlates
how much users agree on the recipient user's votes.
I disagree with that line of thinking. Unless you only have customers
that are Republican Methodists or Methodist Republicans would that work
well. Unless maybe if you have 10 million users. I have never been a
Methodist, but was a Republican until 2004, about 16 years I suppose.
Right now I am just hopeful that someone with Integrity and
consideration for humankind takes a go at things.
Believe me it works. Different people correlate by the Weighted Root Mean
Squared Error of their votes on domains. It is not picking up all nuances of
personality and choice, but it averages out unless you are just really super
unique in voting opposite of all possible permutations of existing userbase,
which becomes harder to achieve the more users there are relative to # of
domains seen. Even if so the correlation realizes you are statistically unique
and you do not get correlated well to any other users. In return for being so
unique, AccuSpam would be less effective. But that is not the within 3 sigma
case.
hmmmm. I don't recommend that anyone use POP. I get too many customers
that think they can store all their email in their Inbox at work with
"save on server" so they can get it at home.
Hotmail and Yahoo give 2GB now. So why not. If users want it, then the way to
grow from 900 domains to 9000 is to give them what they want.
And that is like playing
Email Jenga. One day you get in the office and are receiving 2500
messages because the hottest email client on the market loses it's mind.
So set mailbox limits. If it is going to overflow at 2GB from attack, then
leaving 10MB till the end of day is not the problem.
You take care also,
