Hi I’m new at mailcow now it is running all seams perfect besides hotmail marking as spam but that is other history…
I can get email on SOGO send and receive and at other docker container on same server runnning nextcloud I can get rainloop to connect and work. Same as for thunderbird or windows mail app, also cellphones android or IOS and a wordpress page test got ok and no issues at all reaching the smtp.
But on other server that has and application that send to clients invoices I got a timeout error as the smtp not responding ever, and also on any online testers like these one https://www.gmass.co/smtp-test I got
“ERROR: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 38.242.213.XX:465”
Please any advice to resolve it 😭
