I have read many posts here regarding multiple domains externally hosted. I can’t find anything definitive on using MiaB as my e-mail server for externally hosted domains, meaning I want my website to send e-mails via MiaB.
I have MiaB running for almost a year now. Works great. I use it for e-mail for several domains. All domains use MiaB as their Nameserver. I have used Custom DNS page to set A records for my websites on external servers and all sites work great.
I would like these external sites to be able to use MiaB as their SMTP server. I just need it for outgoing mail so users of my site can get e-mail to reset their passwords or to broadcast an e-mail to our users.
My site can connect to Gmail SMTP or Mailtrap without an issue. It can not get access to my MiaB server. One of the differences is that Gmail and Mailtrap both use SSL where MiaB requires STARTTLS. Not sure if that is the issue that is stopping me, or not. Either way I really wish I could get this working.
This seems like a pretty basic function you would want a mail server to do. What I am I missing here?
Thanks for any input.
