Exchange 2010 POP Send Problem

Posted on 2011-10-22
Last Modified: 2012-05-12
I have a new Exchange 2010 setup.

OWA & Exchange works perfectly.Can send /receive mails internally & externally

Problem is with POP.I can send/receive to internal users.I can also receive from external users but I can't send to external users.

I get error unable to relay 5.7.1

I have removed the Client & Default receive connectors & created a single receive connector which is working fine for OWA & exchange.

When i create a new accepted domain example *  and select External Relay Domain then I can send to all external users using POP.BUt I don't want to do this because of relay issues.

Please advise if i have to create a new send or receive connector for POP to start sending mails externally.

Any feedback will be appreciated.

    You have removed the client connector that is the reason

    create the default connector as shown and it should solve ur problem

    Also make sure you have enabled certificate for the POP,IMAP services..
