Can we have a smtp app in CasaOS?
Most ISPs block port 25 to prevent spam, so running an SMTP server on CasaOS usually won’t work for sending or receiving mail directly. Even if you use alternative ports, email between servers still needs port 25, and deliverability from home IPs is poor (lots of spam/junk folder issues).
Better option: Use a third-party SMTP relay service or your ISP’s mail server for sending emails from CasaOS apps. This avoids port 25 issues and improves reliability. Running a full mail server at home is rarely practical these days.

Hello.
I installed poste.io on CazaOS manually, but an installation via BigBear would be easier.
Sometimes the configuration gets back to 0 and so I lose all my e-mails.
For sending I go through Gmail (application password) and emails all arrive.
