Hi, Hoping someone can help me configure this. I have assigned a dedicated IP and setup a DNS for mail.domain.com to the dedicated IP address. Now mail.domain.com is used to send email (SMTP). However, when I look at the headers of the received email, it is the domain and IP address of my primary reseller domain. I want the IP address and domain to be sent from mail.domain.com in the headers. I've enabled "Send mail from account’s dedicated IP address" under Exim configuration, but it isn't doing it. What do I need to change, so when email is sent via SMTP via mail.domain.com the dedicated IP address for this domain is used rather than something else. Many thanks!
