This is odd, we had a customer who also uses aol forward us some spam that
was send to a lot of email addresses beginning with 'z', (his began with a
z also) it appears that spammers are picking random addresses that start
with a letter of the alphabet and spamming commonly picked addresses.

Perhaps they were trying to relay through your system, or the spammer is
on your system =)

Check your system, can anyone relay trough it. also check your
mail-queue, it usually is a positive sign of an known open relay if it's
full of mail not sent by your system or authorized systems.

also check if you are listed at orbs or other systems like that.

i would suspect an open relay from these messages... (well not if you
have sent those mails to all of those aol.com addresses.)
