Parsing partial attachment panics fatally

[HeinOldewage]

Panics with error panic: Expected attachment to contain a header section and a body section.
when a client disconnects before completing a send.

The simplest way to reproduce is to run the example in gopkg.in/gomail.v2 and attaching a file that does not exist( the library panics after the send starts and disconnects before completing the send).

I do realize that the incoming email is part of the problem, but it would be nice to use this application in an environment where email messages are hostile.

Yeah I see your point. I agree it will be better for MailSlurper to not freak out when the client misbehaves. I'll put this on my list to fix. Thanks!
