[Mono-list] Re: Encoding email message ??

[Scott Willeke]

Roman:
Additionally there are lots of resources on the Internet for dealing 
with email. A quick search revealed a list of articles that may be of 
interest to you. A couple from the first page that were particularly 
relevant are below:
http://www.codeproject.com/csharp/despop3client.asp
http://www.eggheadcafe.com/articles/20040527.asp

I've written some some email/mime code in the past, and found that, 
despite the terseness, the POP, and MIME RFC's such as RFC2045 noted by 
Robert are invaluable.
