Yes, I have seen similar e-mails and yes, this appears to be word list probes to see what will and will not pass through your filter. Once they compile a reasonable trigger list, they will omit those words from their SPAM messages. This also explains why the e-mail is coming from random sources. If it came from a real address, they know that any reasonable admin would add the domain to their block list.

Perhaps some spammers trying to test circumvention of anti-spam filter ? Just filling mail with random words to test if this can pass some score-based filter like Baysian filter?
If those messages are accepted, they will try later with some advertising for a Miracle Pill to make some part of your body bigger ? ;-)

Hi everyone -
For days now, I've been receiving weird messages, with a few lines of apparently random, garbage text, like this:
highest bailiff nomad father advise heir
oxygen honorarium allegro reveal wronskian indentation coachmen
deficient tribute arcturus mitigate bypath
Full-Disclosure - We believe in it.
