I sent an email a few weeks ago and got the error message below bounced back with it. This error message now appears with *every* email I'm sending out, regardless of what the address is.
I've tried to get rid of the error message, have deleted the original offending email, have cancelled the send instruction but all to no avail. HELP!
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '546
[email protected]'. Subject 'Updated glossary for C20046560', Account: 'pop.ozemail.com.au', Server: 'smtp.ozemail.com.au', Protocol: SMTP, Server Response: '550 Invalid recipient: <546>', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
Cheers
