Periodically I'm getting SMTP errors using Mutt. They come in the following format, always when sending to addresses involving Comcast or other major ISPs:
host gateway-r.comcast.net[204.127.198.26] said: 550 24.20.51.17 blocked by ldap:ou=rblmx,dc=comcast,dc=net -> Comcast.net subscribers are not permitted to directly connect to this mail server. If you are a Comcast Commercial Services customer and need support, please contact [EMAIL PROTECTED] (in reply to MAIL FROM command) Any suggestions would be appreciated.
