i see this at the bottom of spam email all the time. what is it?

Random characters to help beat spam filters.

random? it's the same code, if i did a search in my mailbox on that string i'd find probably 1,000 emails with it in it.

Well then my ONLY guess would be that the spammer's random code generator is broken. ;)

Normally that's what something like that is...
But now I am perplexed at your query.

that would be my guess too

but you never know. could be secret code :glugglug

bounce checker. you send a random string, you check your bounces and reverse sort against what you get back vs what you sent. you don't see what you sent, its either valid or /dev/nulled.
