[Mono-list] Sending mail with smtp.gmail.com

[toutu]

Thank you for your attention.
I revised different thread. My source code is very short.
I am using smtpclient class and it seems to have a behavior very different
from WebRequest class.
If I run certmgr -ssl smtps://smtp.gmail.com:587 certmgr crashes too.

Thanks.
Regards.
