I fixed my POP3 / Mime parser problem!
I am once again able to read all mails and attachments that ever hit my mailbox. The problem itself was a simple error in one of the MIME headers ( missing quotes to be exact ). But I ended up making some major changes to my setup.
Since OpenPOP.NET completely refused to download the faulty messages from the server I kick it out and user the NandoF POP client instead. I upgraded it to support SSL connections and made it bit less strickt in order to support my faulty messages. I also cleaned up my old import code so I now have a very solid email download component which I hope will hold a few more years.
Should anyone be interested in the adapted NandoF code feel free to ask. I originally planned to put a download in this post but it’s late and want to sleep. �
