I get the differentiation here that you are referring to.
ok
But any of the solutions mentioned (as I understand) them do require extra effort to mitigate these problems.
yes, it was easy getting DSL subscriber access, but it's going to be harder and harder to deliver mail from those nets.
One of the reasons we became IMail customers was because of the ease of setting up and using the product.
that aspect is completely unchanged.
I talked to Covad and they won't setup our IP for reverse DNS.
ok
Our domain name does have an A record and MX record associated with our IP
ok, and you have PTR, so you're not that bad off.
and works on the whois.
irrelevant, mailservers don't query whois for anything
But this doesn't help with Reverse DNS.
no
I did try pointing our IMail SMTP gateway option to point to the Covad SMTP server, but this failed.
yes, the abuse coming from subscriber networks is so horrendous, and apparently so hard/expensive for the network operators to police, they don't even trust their own subscribers' IPs for unauthenticated relaying.
Covad is going to turn on Authentication starting Oct 7th, so even if this worked, it would probably be short term.
Ask Ipswitch if Imail SMTP can be improved to support SMTP AUTH for the "send all mail through gateway" relaying.
For our inter office solution we will just use the Covad SMTP server from our email clients.
However this leaves our Web Messaging partially working which our remote people are using.
As a side note I noticed that as an Earthlink customer at home stopped letting me access our business SMTP server remotely.
They must be blocking remote port 25 access now?
that's one way to stop abuse from Earthlink nets, but it forces most clients through earthlink SMTP gateways, where Earthlink must have instituted a lot of mail log surfing bots to watch for abuse.
