Unable to send mail to a mail Id that is outside my domain

[subrahmanya]

Hi All

I am using Poco 1.3.1 C++ portable components. I am trying to send mail to some Gmail Id. I am using SMTPClientSession::sendMessage() function to send mail. I have set different parameters before calling sendMessage() function as specified in the sample program Mail.cpp. When I execute sendMessage() it throws an exception "{"Recipient rejected: <xxx@gmail.com>: 550 5.7.1 Unable to relay for xxx@gmail.com"

If I try to send mail from a machine s158344@abc.com to mail Id xxx@abc.com, i.e. within same domain, there is no such problem. I get mail to Id xxx@abc.com

Does anyone know the reason for this behavior? Am I missing something here?

Thanks in advance

Hi Subrahmanya & welcome to Poco Forums,

I am using Poco 1.3.1 C++ portable components.

Never heard about that one.

Does anyone know the reason for this behavior? Am I missing something here?

All I can think of is that authentication isn't set to address Gmail, although all this is way beyond my understanding.

Hope someone can help you to identify what's really wrong, since I'm only guessing here.

Sorry.

Pocosystems is not involved with these components. I'd recommend to contact their author.
