Missing colon in header breaks parser

[honcheng]

Emails with runbox.com omits a colon for the 'From' field in the header in the first line.

e.g.

From email@address.com Fri Feb 14 08:55:52 2014

This causes everything in the header to be displayed in the email body. Mail app seems to be handling this email without a problem, but MailCore breaks.

It's strange that runbox.com does that. Should MailCore be able to handle this? Not sure what is runbox.com intention with the first line because the 'From' field is also available further down in the header.

I think it's because the first line of that message uses the so-called "Berkeley Mbox" convention (note that that line contains not only an address but also a date).

That said, it would be nice to have a workaround for this common issue.
