Are you asking if sending email over a dedicated IP address is required?
NO, I am not asking whether a dedicated IP is necessary to send mail vs using the main server IP. I am asking what the definition of DEDICATED IP is in regards to the setting in question.
We have set up the user in question (a reseller) with his own IP address. That IP address is currently only used for his main website account (plan has no email) and a second account with full email functionality. He is using authenticated SMTP to send mail off the server. We have this setting configured to ON:
Exim config editor->Basic Config->Domains and IPs
Send mail from account’s dedicated IP address [?] = ON
Automatically send outgoing mail from the account’s IP address instead of the main IP address.
Outgoing email is okay, it's just that the above setting is not working, his email headers are still showing the main server IP.
It says "send mail from account's ***DEDICATED*** IP address".
Is it failing because it is not a dedicated IP seeing as how it his being used for 2 accounts rather than just ONE - is it being interpreted as a shared IP rather than a dedicated IP?
Or should it work anyway and the word 'dedicated' should not be construed necessarily meaning a SINGLE account, but rather any assigned IP other than the main server IP?
