I have been getting this error message with a couplke of clients now.  It
only happens when someone from yahoo wants to send a few of my clients an
email from yahoo.  My clients can send them an email with no problem.  DNS
appears to be ok with no other domains being blocked.  No blacklists, etc...
Let me know if you need more info.

Sorry, I wasn't able to establish an SMTP connection. (#4.4.1) I'm not going
to try again; this message has been in the queue too long.
