I am using Thunderbird and I need to somehow manipulate and process the e-mails that are stored in inbox.msf file using C# language. In C# I am using SS2.Pop3 library.So, I was wondering, how do you parse an .msf file?
.msf files are mail summary files and do not contain emails (admittedly, it's been like 10 years since I looked). Thunderbird uses standard UNIX mbox formatted files to store mail.
There is only 1 parser for those files available in C# and that is MimeKit (which also happens to be my library).
I'm pretty sure that if you have an Inbox.msf file, right next to it should be a file called Inbox which has the actual mail in it. That's the file you want to parse.
