Hi,
Recently I've been getting lots of very similar spam. The sending address seems to always be info@some.domain, the sender's name is one of an apparently fixed set of firstname lastname, the subjects are always something very generic like "Read this," "Hello," "Hi," etc., the body of the message consists of English words in a seemingly random word salad such that no meaning can be derived from the message, and I'm betting there's a picture or something that's supposed to hide the dummy body text in order to show the real spam message. Anyway, these Emails seem to be coming mostly to root, webmaster, and postmaster addresses at my domains, which I've been forwarding to my primary Email account. My question is, are there any negative consequences I might face for disabling delivery to these addresses by returning 5xx delivery failure messages during the SMTP stage? I know there are a few RFC's which specify that postmaster@ must be a valid address at all domains. Are there any Email or other systems that actually care about this, and will declare me to be an evil, non-compliant server administrator if such addresses do not accept mail?
