My question is about SMTP (TIdSMTP component) and TLS.
UseTLS property can have the following values:
After doing many searches I am confused about those values.
This is what I found.
utNoTLSSupport = unsecure connection
utUseImplicitTLS = uses SSL unconditionally from the moment the socket is connected
utUseRequireTLS & utUseExplicitTLS = allow TIdSMTP to query the server for its capabilities after connecting and then enable SSL dynamically only if the server allows it
Use utUseRequireTLS if you do not want to use an unencrypted connection
Use utUseExplicitTLS if you are willing to use an unencrypted connection
I am a little bit lost now...
In Thunderbird you have the options "TLS", "TLS if available" and "SSL". To wich UseTLS properties values these options match?
Please help me!
