Error with EmailConnectPOP : connect failed with a starttls authentification

I need to receive e-mails with an POP account that use a "starttls" authentication but it does not work after many tests in conformity with the documentation. The EmailConnectPOP function returns "ERROR" and the LastEmailError returns "connect failed". It is OK with a Gmail account that use SSL but not with the account that i need to use. In the documentation, it seems that several optionals parameters are possible but only "ssl=1" is indicated. I proceeded to theses tests :

 

EmailConnectPOP( [serverAdress] ; [AccountName] ; [AccountPassword] )

Error : "only valid after entering TLS mode"

 

EmailConnectPOP( [serverAdress] ; [AccountName] ; [AccountPassword] ; "ssl=1" )

Error : "Connect failed"

 

However i tested with success this account with Thunderbird and Apple Mail with the same parameters.

 

I tested my Gmail account with the EmailConnectPOP function and it worked correctly : result = 1.

 

Can anyone help me ?

 

PS : Excuse me for my bad english...
