Can't connect via SMTP

[LukasReschke]

I just tried to deploy this here and everything works fine, except the SMTP part which makes registering impossible. As soon as somebody tries to register a verification mail will be sent but somehow Django refuses to connect properly to the SMTP.

I've configured the following and on the virtual machine next to this one the settings work quite fine for phpList:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'mx.nextcloud.com'
EMAIL_HOST_PASSWORD = 'VALID_PASSWORD'
EMAIL_HOST_USER = 'VALID_USER'
EMAIL_USE_TLS = True
EMAIL_PORT = 587

The thrown error is:

cc @adsworth @BernhardPosselt Any ideas?

[adsworth]

are you sure that it's pulling those settings? It looks like it's trying to connect somewhere that isn't accepting connnections and:

[21:59 adi ~]$ telnet mx.nextcloud.com 587
Trying 88.198.160.131...
Connected to mx.nextcloud.com.
Escape character is '^]'.
220 nextcloud.com ESMTP Postfix (Debian/GNU)
QUIT
221 2.0.0 Bye
Connection closed by foreign host.

that works. So I think it's trying to connect somewhere else.

Interesting! I now looked at the stack trace a little bit more and it shows something contradicting:

Just wondering why it eats the port but not the domain name … mhm … 

Sorry. I am an absolute Python newbie 😉

[LukasReschke]

Ok. I'm officially stupid, when I entered the SMTP config I didn't notice that at the end of the default file another mail host was already defined.

Working now 🙈

[adsworth]

that has tod o with the time of day and day of week, not intelligence. :)

Btw, got apache working using

<VirtualHost *:80>
WSGIDaemonProcess apps python-home=/opt/appstore/venv python-path=/opt/appstore
WSGIProcessGroup apps
WSGIScriptAlias / /opt/appstore/nextcloudappstore/wsgi.py


Alias /static/ /var/www/html/static/
Alias /schema/apps/info.xsd /opt/appstore/nextcloudappstore/core/api/v1/release/info.xsd

<Directory /opt/appstore/nextcloudappstore>
    <Files wsgi.py>
        Require all granted
    </Files>

<Directory /opt/appstore/nextcloudappstore/core/api/v1/release>
    <Files info.xsd>

    Require all granted
    AllowOverride None

All changes in python code now need to be reloaded by restarting (or maybe reloading) apache :)
