While not "tied" to the ISP, we've otherwise had very good luck with them.
We must use their relay because places like AOL and other huge mail
recipients will not accept inbound SMTP from dynamically assigned IP
addresses (like when we have exim connect directly to the recipient). In
order to be able to send mail to everyone in the world and not have it
bounce, we must relay thru the ISPs mailer.
These 550's occur fairly rarely (once out of 750-1000 outbound mails;
probably some timing window in their "POP before SMTP" implementation).
Since the failures occur so rarely, I'd like exim to automatically retry the
message as it will almost certainly be accepted the next attempt.
