Some time ago, using SME6.01 or earlier, I started getting send failures from addresses at AOL among others. They were no longer willing to accept email from a dynamic IP address, so I fixed this by routing all outgoing mail via my ISP SMTP server.
When I installed RC2 a couple of weeks ago, I forgot to set this up. Strangely, I did not get any outgoing message failures from my local network, but my stepmother connecting to my SME server remotely could only send email to the local network and all outgoing messages bounced.
I have now setup to use my ISP SMTP for outgoing, but I did some tests before and after to a hotmail account.
The emails from SME server to hotmail direct all got tagged as junk mail, but after routing via my ISP, they got through to my hotmail inbox.
2 questions:
1) have most large ISPs stopped refusing all direct email from dynamic IP addresses and started using more sophisticated analysis?
2) Is there something about a remote user using Outlook connecting to my SME server which produces email bounces not experienced by local users?

Dunno; seems like some large ISPs seem to go through cycles where they overzealously block huge swathes of domains and IP ranges, announcing it as a huge improvement in securty, only to revert back to the previous setup when the volume of compaints rises.
I had a similar probale to yours with Earthlink, and they just wouldn't do anything about it; in desperation, I purchased a static IP address, but as this was issued by BT in the same general block that contains their dynamic IP addresses, Earthlink still thought I was coming from a dynamically-assigned range).
I refuse to delegate to my ISP's SMTP server, as that defeats a major object of running my own mail server anyway.
