Hi,
    Please find a patch attached for testing. It fixes the following:
 
1) Proper handling of STARTTLS on SMTP, taking CURLUSESSL_TRY into
account.
2) Falls back to RFC822 HELO when EHLO fails (and SSL not required)
3) Use of true local host name (i.e.: via gethostname()) when available,
as default argument to HELO/EHLO
 
Good week-end to everyone,
Patrick
