    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?
