I send and receive email many times a day, but there are
two email addresses (both are family members) where I get
a message from the System Administrator saying:

Your message did not reach some or all of the intended
recipients.

Subject: test
Sent: Date/Time

The following recipients could not be reached:

(person's name and email address, Date/Time
553 sorry, that domain isn't in my list of allowed
rcpthosts(#5.7.1)

Can anybody help me with solving this problem?

Thanks
 
You probably need to set up authentication to your outgoing mail server,
which can be done on the "Outgoing Server" tab for your mail account.
