Network Error, Exim4 not sending emails

[herandes]

Hi, i have a problem with Exim4 on Debian 7.3, after apt-get upgrade exim4 stops sending email.

The same issue occurs when installing on a fresh machine with Debian 7.3, the log show:

2014-01-15 12:24:59 1W3PVj-0004Yl-Rq gmail-smtp-in.l.google.com [173.194.68.26] Connection timed out

someone have any idea? tanks in advance

Can you check if configuration was changed after upgrade?
Following file /etc/exim4/exim4.conf.template should like this
