Cpanel Smarthost Mailgun with multiple domains? not possible?
Hi everyone,
We've hit a brick wall with one of our service providers and the IP allocation across some of the servers. The IPs aren't blacklisted or RBL'd anywhere but they're still resulting in email being flagged as 'spam' on anything sent to an address hosted on office365 or gmail / g suite.
Which is a problem for the client hosting accounts that its affecting obviously.
I was directed to using a smarthost setup and stumbled on this that was posted by cpanel 3 days ago.

Hi, The Smarthost SMTP Relay blog post explains how to make smarthost configuration serverwide. You don't need to do anything acount-by-acount. Or do I misunderstand your question, that you indeed want an account-by-account approach? As answer to your first question/issue, even though you are not blacklisted on the "official" RBLs, both Google and Microsoft also have their own blacklisting/reputation techniques. Usually having proper reverse DNS configured and using SPF+DKIM on your domains helps a lot. You may also want to have an extra look at Google Postmaster Tools, that can help you identify issues towards GMail accounts - and Microsoft SNDS (equivalent tooling) Also looking up your ip addresses at the different ip reputation sites, may help giving an indication on where the problem might be :) - Michael 0 -

The 'Smarthost SMTP Relay' blog post does reference how to set it up serverwise, but the actual service doesnt work like that. Mailgun doesnt support a single account on "their platform" that can support multiple domains, its 1:1 relationship of domain per account on the mailgun setup, but cpanel only allows provision for a single user/pass on the exim configuration for the mailgun or sendgrid account. I will be trying the SNDS toolset again, previously though all checks/scans on every service we could find come up clean, hence trying to go this avenue and hoping for a better result.You can set this up for specific domains as far as I am aware you'd just specify the domains it includes in the domains section of the ROUTER.

I'm sorry they weren't helpful for you, you might want to reach out to MailGun's support to find out how you use their product with cPanel as well. 0 -
Ironically they said "we have lots of people running cpanel happily using our service, please reach out to cpanel support to find out more information" To be fair, the cpanel smarthost blog post +cpanel mailgun instructions work, if you only run 1 single domain on your cpanel server. If you run multiple (which mailgun/ sendgrid support cant see to understand - you are up the creek without a paddle so to speak it seems) 0 -
@SupraMario Did you find any solution for using (Mailgun / Sendgrid) for multiple hosted websites on your server? 0
