Major fail for Comodo in the eyes of some users around here.
The subject of the email is "I unzipped his pants and his package was enormous"
Seriously, I don't need to look at SPF records, domain blacklists, headers or anything else to figure out this is going to be spam. Yet Comodo happily allowed it into my users' inboxes.
Sorry, just had to vent about this one. Still quite happy about the amount of spam we are not getting.
