SOLVED Commento not able to send mails

[timbo]

Hello o/
Sadly Commento can not send mails, i am not sure if it is due to cloudron or commento itself. The Log says:

I would appreciate any help!

This should definitely work. In fact, @nebulon submitted a patch to commento just to make email sending work which I believe is part of the Cloudron package already - https://gitlab.com/commento/commento/merge_requests/88 . I will let @nebulon comment

Hey Girish,
thanks for the response. I'm excited to hear from you guys @girish + @nebulon !
As for now, i reinstalled the app and it still does not work.

[nebulon]

I just did a verification on my instance and it can send emails as such (already the initial user-registration requires that to work).
Not sure how you triggered

Nov 19 13:45:54 2019/11/19 13:45:54 [ERROR] smtp_owner_reset_hex.go:19 smtpOwnerResetHex(): cannot send reset email: gomail: could not send email 1: gomail: invalid address "=?UTF-8?q?XXXXXXXXXXXX<post@XXXXXXX.XX>?=": mail: expected single address, got "?="

But something does look odd with that email address. Does the address by any chance contain special characters, which may break something in commento?

[timbo]

Hey @nebulon
no I don't think that the adress does contain any special characters. I just exchanged the complete adress with "xxx..." for privacy reasons.
It is a complete normal email adress, with characters from a-z and the TLD is .cc
It is also the first email being registered in this instance, right after the setup.

Just for control - i will reinstall the app and try another emailadress, one which is hosted at protonmail.com and report back.

Report back;
It is not an issue with the email adress, it is the name.
In the Name is a Umlaut which causes the error.

So it is kind of solved.

Reporting back;
Tried several things now, Umlauts in generel do not work at commento signup forms.
Opened an Issue on Gitlab.
