Sending Emails not working

[NoobKeksTV]

I have the problem that after updating to the latest version of BBB-Docker, sending invit emails doesnt work. It seems like my mailserver (mailcow-dockerized) running on the same server doesnt even get a connection from bbb (checked postfix logs, no connection)

These are my SMTP setting inside of my .env file Note that these exact settings have worked fine befor!

SMTP_OPENSSL_VERIFY_MODE=none
SMTP_SERVER=mail.xxx.com
SMTP_PORT=587
SMTP_DOMAIN=bbb.xxx.com
SMTP_USERNAME=noreply@xxx.com
SMTP_PASSWORD=xxx
SMTP_AUTH=login
SMTP_STARTTLS_AUTO=true

# Specify the email address that all mail is sent from
SMTP_SENDER=DerGroßeBlaueKnopf

I had a similar issue. You can debug if the SMTP config is actually recognized by running:

docker-compose exec greenlight bundle exec rake conf:check

For me it didn't even mention SMTP, so completely restarting the whole project made it working for me.

tried this and it says this:

Checking environment: Passed Checking Connection: Passed Checking Secret: Passed Checking SMTP connection: Failed Error connecting to SMTP - execution expired

however out other software & clients are able connect to the mail server with these exact adress, port, email login & passwort. Does it have something to do with it being in a docker container? Or could it be that i diisabled conections to our server origin ip so only cloudflare connections work. But again other websites we have use ethe exact same login info & are on the same host so if firewall is an issue, they should also not work but they all work without problems.

In my setup I don't have SMTP_OPENSSL_VERIFY_MODE specified. Also I am not sure but is it possible that ß character in sender name throws your SMTP server off? Oh and I just noticed that SMTP_SENDER doesn't follow name@domain.com pattern - could that also be a reason?

SMTP_OPENSSL_VERIFY_MOD is only specified because i have a leets encrypt certificat (i use mailcow-dockerized) and before upgrading bbb-docker i had to use this for it to work.

idk about the sender but as far as i know the sender is just the name of the sender showing up in your email.

Those exact settings also worked before upgrading my bbb installation. i had to update tho because of the voice socket problems in newer versions of chrome & other browsers (incompatiblity / unsafe methods)

these are greenlight configs, rather unrelated to bbb-docker and probably after a year resolved? if still an issue, feel free to ask at the greenlight mailing list https://groups.google.com/forum/#!forum/bigbluebutton-greenlight
