My emails keep getting returned to me with a message reading " 553 sorry,
that domain isn't in my list of allowed rcpthosts (#5.7.1)"
What does this mean and how can I fix it? These are emails that I've sent
things to before...
Thank you for any help!
 
Does your ISP/Free Email Provider require you to authenticate with them in
order to send e-mail messages?

No, it's a domain through my company and I've never had this problem before.
If I type in their email without the 'name' sometimes it goes through.. it's
picking and choosing which ones though and is so frustrating!

thank you for any help you can offer!
