[Mono-dev] Problem with CA sending certified emails

[Joe Dluzen]

Hello,

I tried replacing the Mono.Security.dll file with the one from 2.6, it
didn't work for me:
http://stackoverflow.com/questions/2884290/ssl-authentication-error-remotecertificatechainerrors-on-asp-net-on-ubuntu

I tried having a parallel installation of 2.6, and redirecting
mod_mono to use the new one, it didn't work for me:
http://lists.ximian.com/pipermail/mono-aspnet-list/2010-March/000668.html

My next attempt is to use http://badgerports.org/ to upgrade the whole
thing to 2.6. My current workaround is to use:
http://ubuntu-tutorials.com/2008/11/11/relaying-postfix-smtp-via-smtpgmailcom/
and send mail to localhost.
