Hi Dmitry, Thanks for your response. Non-ascii international
characters are not allowed in email address as per RFC5322. This
problem is happening with Outlook when user inputs any of such
character in email by mistake and blows up the complete recipient list
after Q encoding applied by IConverterSession (as this email address
has no @ sign to distinguish from other addresses). I really do not
want to parse the complete recipient list for each message before
message dispatch. What would be your suggestion to deal with such
scenarios, if i still want to use IConverterSession?
Thanks,
