I receive a ERROR 703 (Invalid response received on 'USER' command) whenever I try to connect to POP3. Even when using the tester tool. Does anyone know why this may be happening?

Hi,

Thank you for your post, for some reason the authentication failed. Is it possible to send the POP3 logfile.

Best regards,

Thanks for your reply, here is the error message (I've triple checked the url, username, password, etc)

Also, whats odd is it doesn't seem to care what username/password I put in...this is the pop3 address though:

I was able to get past this error by setting the following as the Authentication setting....

objPop3Server.Authentication = objConstants.asAUTH_POP3_PLAIN

Also, I had set the pop3 address to be an IP addres, not sure that this made any difference though....

Hello Jared,

Thanks for letting me know. The APOP authentication is causing troubles for some mailservers. Switching to plain auth always solves the problem.
