Mailing Macro Issue

[tresB]

Hello all,

my mailing works fine when i try to send mail withing my own company. But shows error when i try to send outside like gmail, yahoo or such addresses. I think its a basic setting problem which i am missing. Can you please help me out?

Thanx.

Please check your SMTP server IP.

There is some security issue.
