sendmail problem

    recently i started using an exchange hosting company to host my email and i changed my MX records so that email to [email protected] goes to their server. everything is working fine except for email sent from my web server (

    specifically... i have a contact page ( on my website that uses a php script to send email to [email protected]. it worked just fine before i started using the exchange host. actually the script still sends a message to the local 'info' account.

    in sendmail i added '[email protected]' as an alias to the local 'info' user but this has not made any difference.

    i think the problem is that somehow the web server has no idea that the exchange server exists -- even though the MX records point to it.

    any ideas how to fix this? thanks in advance!

    Use the mailer table to direct the mail in /etc/mail/mailertable

    Code:		smtp:[their_server_name]
    cd /etc/mail; make restart

    thank you. i have done exactly as you suggested but it hasn't solved the problem. it just seems strange that sendmail isn't looking to the MX record for the domain - if it did it would know where to send it.

    The mailertable is designed to allow you to by pass the mx record i thought that is what you wanted ?

    what is the output of
     sendmail -bv [email protected]

    Thanks for sticking with me on this. In fact I don't want to bypass the MX records. The MX records are correct.

    It's just that sendmail is not bothering to check the MX records and thinks that [email protected] should be sent to the local user 'info'.

    Actually, I think what I want to do is to force sendmail to look to the MX records to find the mail server.

    any suggestions?

    just a thought...maybe the solution is to somehow tell sendmail that it is not supposed to handle mail addressed to [email protected]

    i want it to handle local mail to local users without the @domain in the address so that programs can function properly.

    not sure if this is making sense the way i'm describing it...

    remove the domain name from /etc/mail/local-host-names

    hmmm...there is nothing in that file except for the first commented line:

    # local-host-names - include all aliases for your machine here.
