Customer using own SMTP server reported, that they can't send emails anymore. After some investigation turned out it was additional IP to withelist: 135.116.144.4.
Documentation (Mailgun | SuperOffice Doc) is mentioning only this:
It is a good idea to allow (whitelist) access to your own SMTP server from our Online environment based on IP address: 91.123.49.126, 91.123.49.180, 91.123.49.237.
I could find the IP 135.116.144.4 only mentioned in support requests, but it's nowhere in documentation to find.
Please add IP 135.116.144.4 in the documentation.
