I have just installed CyberPanel on DigitalOcean. I have created a mail account, and then I open Rainloop and try to send an e-mail. But the e-mails stays in the mail Queue, with the error code:
- [{“address”:“XXX@XXX”,“delay_reason”:“connect to YYY[2a01:4f8:241:1f86::2]:25: Network is unreachable”},
- {“address":"[email protected]”,“delay_reason”:“connect to alt2.gmail-smtp-in.l.google.com[142.250.150.26]:25: Connection timed out”}]
When I send a mail to the created mail, it works fine. What seems to be the problem here?
