Undefined method `downcase' for nil:NilClass when processing mail

Bug
1

I’m getting (using ~ yesterdays build):

when importing a specific email. I can post the email privately if needed:

Unrecognized error type (NoMethodError: undefined method `downcase' for nil:NilClass) when processing incoming email

Any chances you could send me the raw version of said email via PM?

The e-mail is missing a From: address. I’ve seen that problem when sending hand-crafted test e-mails and forgetting to put in a From: line in the headers.

I sent @zogstrip the mail, it did have a From: field.
