Periodic Mutt SMTP Errors
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 support_biz@xxxxxxxxxxxxxxxxx (in reply to MAIL FROM command)
Any suggestions would be appreciated.
