I tried to send and email to multiple recipients and got this message but it changed the email address each time.

An error occurred while sending mail. The mail server responded: 4.1.1 626rb7nvIwhW1 Too Many Recipients (TT501).

Please check the message recipient "fish222@btinternet.com" and try again.

I now get the same message when I send an email to a single recipient. The email address is correct. How do I fix this?

some mail providers issue this error if you are not logged into their mail system when you try to send mail.
