My customer has an existing Exchange server that is hosted seperately from their web site. I have set up a domain for them (domain.com) and there are some ASP scripts on the website that I am testing. I have not redelegate the domain yet, and the client runs their own DNS anyways. Everytime the ASP script sends an email to firstname.lastname@example.org Plesk tries to deliver the mail locally (to the catch all mailbox). I want Plesk to send the mail to the actual MX record for the domain. I tried switching off Mail for this domain, but the emails are still going to the catch all mailbox. Is there anyway to force Plesk to use the regular DNS records, specifically the MX record, and deliver any and all mails from ASP or other domains on this box to their Exchange server? Thanks you for any help!
