Business Customer with own Mailserver. They ofter want to know, which of our mailservers they can use as smarthost. We usualy tell them, that they operate an own fully connected mailserver which does not need any smarthost to deliver email to the world.
Some do not agree. The reasons the tell us are:
- It Tech XY has told them that sending via a smarthost is much more
reliable.
It's a pure thing of implementation which everybody can change to be reliable.
- Their previous ISP asked them to use it's smarthost.
Traditions are no reason of course
- Our Server has better 'reputation' than theirs and thus emails are
less likely to be considered spam by some spamfilters.
That can matter - blacklisting is not only a technical thing. You know why swinog exists?
- Some seem to see DNS issues which I never could understand (they
have correct PTR and MX settings for their mailservers).
No reason for anything.
The problems I see with smarthosting are:
- If an email to a recipient does not make it there, we get the blame
even on trivias like 'user unknown'.
What do you mean with "get the blame"?
- We have to punch holes in the anti-spam thorttling measures to
allow them to send more emails / time than the usual private customer does.
I don't understand your point: if you don't like the customer: kick him. If you like the customer: sell him something. It's not about deeper technical truths. Many providers which offers services for small companies and private users allow big floods of mails because it doesn't fit in the price calculation. So you should communicate your technical limits in the AGBs and everything is fine.
If a customer wants more than that find a partner which does this and make a business of that.
