Smtp Connection timeout

[fonia]

Hello,

We have just signed with Cloudron and installed it.
I'm trying to install our 587 SMTP on the interface but I always get CONNECTION TIMEOUT.
I have tried with several SMTPs and always the same problem.

Could you please help me?

And I almost forgot Happy New Year to the whole team!
