#5.5.0 smtp;550 Invalid recipient
Posted on 2005-03-25
I have searched and searched for answer to my question and I have done a set type=MX on the recipient - and got a reply back - this is the message I am geeting when send to recipient
here was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<******.*****.com #5.5.0 smtp;550 Invalid recipient <*****@******.com>>
I was able to send to the recipient from my yahoo account fine - But cannot send succesfully from my exchange server - It always gets bounced back - I made sure my server was in the DNS foward look up - If you cant tell I am kind of new to this and I cannot find a valid answer and how to correct it -
I think the recipient is using an external mail server that is hosted by "speedfactory" - I was able to find this out by using Reverse DNS look up - It seems I have all the pieces - I just cannot figure out how to put them together - Thanks in advance -
