Smarthost for incoming mail

Post by harpwro »

Hello

We configured a postoffice as smarthost for incoming mail, all fine here. But SMTP is used on our mailenable account, and we are having problems with this setting:

- On SMTP security settings if we select 'Authenticated senders must use address from their postoffice', we must have the mailboxes configured on mailenable, but already tested, and incoming emails are delivered here and not at the smarthost external IP;

- If we disable that option everything works ok (no need to have the mailboxes, just one to authenticate on smtp), but it is not very secure, we even noticed someone who uses gmail.com to access their account, sending emails from our server with the gmail.com sender address instead of their domain;

- Isn't there an option to force 'Sender email domain must be local' instead of 'Sender email domain must be local or resolvable through DNS'... because this could solve this particular issue.

Any ideas on how to improve security and keep things running with incoming smarthost?

Thanks
Antonio

Just found there is a tool to fix this on mailenable afterall, at Tools & Utilities Download - Management Utilities - MailEnable Smarthost Routing Configuration Utility

Just tested and apparently will fix this issue
