Postfix- Can receive but not send e-mail
I have installed Postfix on Ubuntu 12.04. I think it's properly installed since I can receive e-mails. Also, I can send e-mails for the same domain. It work. But when I try to send e-mails to outside domains, I always get this messages: Feb 22 13:14:40 elusive postfix/smtp: connect to ASPMX.L.GOOGLE.com[126.96.36.199]:25: Connection timed out Feb 22 13:18:43 elusive postfix/smtp: connect to mx.webstorm.com.br[188.8.131.52]:25: Connection timed out So, what's happening?
