[Classpath-inetlib] SMTPConnection.starttls() status code?

[petite_abeille]

Hello,

I'm slightly confused about what status code SMTPConnection.starttls() 
should check to determine if the STARTTLS command was successful... 
SMTPConnection presently check for code 250 (OK), but it would appear 
that most servers return 220 (READY) instead.

RFC 3207 also mention 220 as the proper status code.

What gives?

TIA.

Cheers,

PA.
