I'm a new member of howtoforge. Thank you in advance.
My problem is as below.
Recently, I moved 3 dedicated servers (CentOS 5.3) from hosting company A to B.
After moving, outbound email is not working.
Application is using only outbound email so, I didn't configure sendmail.
The sendmail service was started and outbound email worked fine.
So, I didn't change any of mail related configuration files and just started sendmail but, not working in new hosting company.
/var/log/maillog ( any of email is not delivered. )

Do I need something to install or configure to make outbound email work?
Does it any matter with hosting company's environment for sending out email?
