Docker Rouncube Problems

[Coslow]

Hello everyone,

os server : ubuntu 22.04
mail server : aapanel

I have a problem with Docker Roundcube settings: IMAP works fine, but there is an issue with SMTP, even though I have checked and there doesn't seem to be any problem with my SMTP server.

docker run:

docker run -e ROUNDCUBEMAIL_DEFAULT_HOST=grias.co.id -e ROUNDCUBEMAIL_SMTP_SERVER=grias.co.id -p 8000:80 -d roundcube/roundcubemail

messages respons send mail:
SMTP Error ()

Do you have a solution?

Thanks

Coslow
