[exim] bank spam

Has anyone generated a regexp to detect this bank-based stuff, such as:

c_support.id2213153140119NOF@???
mailing.id09177-3682385694NOF@???
onlinesecurity@???
generatednotify.id6846-7793428NOF@???
generator.id3785384784762NOF@???
clientcareservice.id6468433113BIB@???

etc?

I'm currently using:

^(?:auto|c(?:are|lient(?:care)?|ustomer)?|generated|(?:gen|e)?mail(?:system)?|mailings|message|post|service|system|tech)[-._]?(?:re)?(?:center|id|mail|message|notify|post|reminder|robot|serv(?:er|ice)|support|team).*@(?:citi(?:bank)?|hsbc|if|natwest)\.co(?:m|\.uk)

which detects quite a bit, but is less than perfect.
