It does introduce another potential point of failure into the mix that then becomes more problematic to troubleshoot for E-mail providers, but it's not terrible to have to do.
I did ask the customer service rep at Cox why they blocked everyone instead of just the spammers, and he of course didn't have a good answer. Seems these guys don't want to police their network. Naturally the way around this is to set up SMTP on a port other than 25, however IMail I think only has one setting for the entire server.

Hello xxxx,
NOTICE: Mail you send from your dynamic IP may not be reaching your
customers.
Many ISP's including AOL,Road Runner have started rejecting mail sent
from residential dynamic IP address blocks in attempt to reduce the
amount of unsolicited email that travels through their networks.
No-IP.com has been working around the clock to provide a solution,
Alternate-Port SMTP.
Altnerate-Port SMTP solves a couple of problems our users encounter when trying to send mail from a residential service such as blocked outbound port 25, AOL and other ISPs rejecting mail based on ip, and inability to send mail from email addresses @yourdomain.com
For detailed information about this service please visit: http://www.no-ip.com/svc/mail/smtp
Some providers that restrict outbound port 25 include
- NetZero
- Mindspring
- MSN
- Earthlink - Flashnet - MediaOne
- AT&T
- Verizon
- Bell Canada
- Cox
Note that Alternate-Port SMTP is for outbound mail only. Should your
ISP block inbound port 25 you will need our Mail Reflector service
(http://www.no-ip.com/svc/mail/reflector).
If you are unsure what service you need or have questions please open a support ticket at http://www.no-ip.com/ticket/
