Good morning,
Today i was setting a new hetzner cloud account for a client, and I installed myvestacp fresh install, and everything was working, even receiving emails, but I can’t send them, later I discover they block for 1 month period or more those ports as we are new users, how am I suppposed to send emails? Is there anything I can do around this until they unlock those ports for me?

Hi,
I already tried that solution and it wont work. I'm not sure if its a hetzner issue, i got other account with 3 years with couple servers running using Myvestacp and i never had any issues.
On this new account they already answered me telling i would need to wait 1 month and pay 1 invoice before i had port 25 and 465 unlocked, but they said port 587 was open. I already tried so many things.

Hi everyone i just did another test, i just set up a fresh installation of myVestaCP on a Debian 12 server hosted with Hetzner. The hostname I used for the setup is server.mydomain.com. Initially, I created an email account
[email protected] and tested both sending and receiving emails. Everything worked perfectly at this stage.
However, after adding the domain mydomain.com to the web server and creating a new email account
[email protected], I encountered a problem. This new email account is unable to send any emails. Whenever I attempt to send an email, it bounces back with the following error messages:
550-Verification failed for <
[email protected]>
550-Unrouteable address
550 Sender verify failed
It seems like there's an issue with email verification or routing for the new domain. I've double-checked the DNS and MX records, and everything appears to be configured correctly.
Has anyone faced a similar issue or can offer any insights on what might be going wrong here? Any help or suggestions would be greatly appreciated.
Some tests dont even deliver to gmail at all, others i send from server 1 email to another server i own and i get "mail dlivery failed: returning message to sender" on both ends, with a 550 smtp auth requried...
Thanks in advance!
