In stunnels *.conf file I can specify the mail server name and the port for a connection.
How can I tell stunnel to use STARTTLS as connect type? How can I tell stunnel to use SSL/TLS as connect type?
Does stunnel support both connect types at all or only one?
Is the connect type for SMTP completely determined by port e.g.:
STARTTLS over port 587 and SSL/TLS over port 465 or can both connect types use both ports?
Assume I do not get the supported connect type information from my webhoster:
How can I find it out from my (client) side? What are there error messages?
