I have client who is not able to post any messages through Yahoo to the
list. Using different Internet email makes no difference either. The
error message is:

 

 

Subject: failure notice

 

Hi. This is a the qmail-send program at yahoo.com. I'm afraid I wasn't
able to deliver your message to the following addresses.

This is a permanent error; I've given up. Sorry it didn't work

 

147.226.7.236 does not like receipient.

 

Remote host said:   550  5.7.1 Unable to relay for
[log in to unmask]

       Giving up on 147.226.7.236

 

 

They have no problem using campus mail program (Outlook) to post
messages to the listserv.

 

Any suggestions would be appreciated.
