Time Warner email problems

[webmaster]

By any chance are you using Metrocast internet service with your Roadrunner email service? Metrocast doesn't allow any outgoing mail servers except their own.

Also, Metrocast is blacklist crazy. If your recipient is blacklisted it can cause long delivery delays. They have blacklisted this site 3 times in the last year although they won't explain why.

You can see that I'm no fan of Metrocast.
