Can you view the header of the mail somewhere? In most programs / webmail sites you can do that somewhere, might be hidden a little.
Something like:

Okay, most of that is just cryptic hashes and weird stuff, but the sender or senders mail-provider might be hidden somewhere. Or just send yourself an email (for realzies this time!) and compare the headers.
(Also, I edited most of the stuff above a little and removed my own address. Subject & Sender are real, as I just copied this from the Humble Bundle newsletter.
And if you use a different mail-provider than me (gmx.de) this might look a little different, I guess?)
The content sounds very random, most of the time spammers want to sell you some enlargements for a certain limb that most males happen to own.
Today I got two spam-mails that said something like "Heyy che hggck out thdgis phharmccggmacy onlixne! [Link which you should definitly not click]" ... or something like that anyways. Looked like they just threw in lots of random characters, I could barely even read it, but the spam filter still caught it. The second one was a reply to something (might've been the first one which seemed strange to me) but looked similar; I deleted both and they were sent by some fake "persons" anyways but definitely not by me. ^^
Did you change your password regardless or are you sure this was not sent from your account? I guess God always knows your password though.
PS: "Your message appears to contain bad language, please edit it out."
... oh. I wasn't aware that "[...]yDfU_KYB[...]" is a swear word if you remove the underscore.
