I have set up codoforum (version 3.3.1) in a hosted environment and am trying (and failing) to have it send out mails using ssl.

My test scenario is the reset password token page.

When I enter a username (or email address) and klick on the "E-mail reset token" button, the ajax loader appears but nothing else happens - no error messages, no email delivery.

mail_type: smtp
smtp_protocol: ssl
smtp_port: [port given by provider]
smtp_username: [username given by provider]
smtp_password: [password given by provider]

I have tested the combination of [password], [username] and [port] with a normal email client and they work fine there.

Any suggestions as to how to solve this?

What are other available options for the value of smtp_protocol that I could test?

Thx.

Update: The solution is to use

smtp_protocol: tls
