Error sending email - wrong version number with protonmail SMTP

[Nachtschwingeswildhunt]

Describe the bug Using the I am experiencing the the self-hosted version via docker, I get the same error as @VincenzoKoestler in this issue . I am trying to use the SMTP services from protonmail (they work with other services) which run on port 587 and use TLS. Is there something I can do here?

I'm also running into this issue. My SMTP credentials work in other apps, but do not with the docker self-hosted version of rallly.

Perhaps, some examples of the SMTP entries in config.env could be helpful. For example, I don't know if the double quotes surrounding the values are necessary or not... I've tried both ways to no avail.

My logs show the following when trying to register a new user:

Error sending email [Error: 000838D1E47F0000:error:0A00010B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:355:

}

It is strange in a way, but I could fix this for protonmail by setting SMTP_SECURE to false. (source: https://stackoverflow.com/questions/66317125/node-js-nodemailer-error-wrong-version-number-invalid-greeting )

@thejohnha This may or may not be helpful for the above but, I'm using a Proton business plan with a custom domain and these are my settings from the config.env file:

[email protected]
[email protected]
SMTP_HOST=smtp.protonmail.ch
SMTP_PORT=587
SMTP_SECURE=false
[email protected]
SMTP_PWD=1234567890ABCDEF
SMTP_TLS_ENABLED=true

Thank you! This made me get it working!
