You can use Mail.dll to easy reply to an HTML and plain-text emails.<\/p>\n

ReplyBuilder <\/em>class allows you to specify custom HTML and plain-text reply templates<\/strong>. Mail.dll will parse HTML, extract body part, and build-in template engine will do the rest to create nicely formatted reply with all attachments, To and Cc fields set.<\/p>\n

The next great thing is that plain-text version of the email is generated automatically.<\/p>\n

\"\"<\/p>\n

You can also take advantage of ReplyAll <\/em>method that makes it easy to reply to all: senders of the message and all To and Cc recipients<\/p>\n

In our example we\u2019ll use Mail.dll .NET IMAP component<\/a> to download first message from an IMAP server. Then we\u2019ll use ReplyBuilder <\/em> to create a reply email message. Finally we\u2019ll use Mail.dll SMTP client to send this message.<\/p>\n
