SMTP in Espo

[akafester]

I think I have tried everything, so I need to hear if someone on here has had the same issues and what they did to resolve it.
The problem is, that I can't connect to a 3rd party SMTP host and what I can conclude is that is on my server. To cement the issue, I have tried with two different mail providers. What I can't figure out though, is how to fix it. The IMAP connection works without a hitch.

Here's some info I have been able to gather. (Everything in bold is omitted)

An EspoCloud instans has also been made to see if that had the same issue. It does not. If works perfectly on EspoCloud.

I will try to get a hold on the 3rd party mail provider tomorrow, but if there are some bright minds out there that can see the issue, please chip in .

If I have left something out, I will get it.
