[Mono-list] mono 2.0 send mail to gmail account error

[Suvi/mg3]

Hi, all,

This error was gone finally after many test and search. May the following
step could help those who have save problems.

1. mozroots, MONO not shipped with any certs, so we'd better import them.
This is very different with Windows.

    mozroots --import --ask-remove --machine

    BTW: I'm not test with " mozroots --import --ask-remove ", I download
all certs into machine store.

2. certmgr, with gmail smtp server, we could import it first.
   
    certmgr -ssl -m smtps://smtp.gmail.com:465

    Also, I'm not testing the User store.

3. System.Net.SmtpClient

    EnableSsl = true;
    smtp port = 587, use the submission port.

And , It should work for you.
enjoy.
