An SMTP_TLS environment variable for implicit TLS connections

[calico32]

Hello!

I noticed the SMTP-related environment variables don't include one to enable SMTPS/implicit TLS (port 465) for the mailer, requiring a code change if one needed to connect via SMTPS. Would it make sense to add a new variable SMTP_TLS or similar to use implicit TLS with the prebuilt image, for example?

Thank you!

Hello, thanks for the suggestion I encountered the same problem, sent a PR to implement your suggestion, it helped me deploy with my mail server, mailu, they recently disabled STARTTLS.

[Edit]: PR got cleaned up, and merged.
