Failure when sending email with SMTP

[jone]

Hi there 👋

I tried configuring accent to send emails through an SMTP server with STARTTLS on port 587.
I have configured correctly

SMTP_ADDRESS=smtp.hostname.tld
SMTP_PORT=587
MAILER_FROM=foo@domain.tld
SMTP_USERNAME=foo@domain.tld
SMTP_PASSWORD=XXXX

When I trigger an email by inviting somebody, the SMTP connection fails with:

│ 16:20:54.715 [error] Task #PID<0.4655.0> started from #PID<0.4654.0> terminating                                                                                                                        │

On Port 587, there is a STARTTLS SMTP service running.
From another container in the same infrastructure the SMTP connection works and the mail is sent correctly with the exact same configuration settings.

How can I solve this problem?

This has been solved in the latest release with some magic TLS options in Bamboo adapter 😄
