mail problem (Relaying denied)
 

Ok here is the problem. I have install squirrelmail on my web server and when i log on squirrelmail nd try to send or recive email everything is ok. But when i try to setup my account on Mozilla Thunderbird and when i try to send email thry Mozilla Thunderbird it say:

An error occured while sending mail. The mail server responded: 5.7.1 <goldy@gmail.com>... Relaying denied. IP name lookup failed [62.162.246.33]. Please verify that your email address is correct in your Mail refrences and try again.


Thanks in advance.

What mail server are you using?

i use sendmail

Config file
 

You need to allow relaying for the gmail.com domain in your sendmail config. I would also restrict it down so only your internal network can relay mail through your sendmail server.
