 We see a new variant with the subject "Your Virgin Media bill is
 ready" and URLs that match:

 uri        __RP_D_00108_03 /\/\d{12}\/[A-Z]{6}\/?$/

Nearly all of these spammails can be blocked with

header __LRZ_BND_MS Content-Type =~ /boundary="-{4}=_NextPart_000_[0-9A-F]{4}_[0-9A-F]{8}\.[0-9A-F]{8}"/ header __LRZ_MSGID_SPAM_99 MESSAGEID =~ /<\d{8,13}\.2017\d{6,11}\@/
meta            LRZ_HEADER_SPAM_99      (__LRZ_MSGID_SPAM_99 && __LRZ_BND_MS)

The version before had a different boundary

header    __LRZ_BND_HU32     Content-Type =~ /boundary="[0-9A-F]{32}"/

...all of which is, sadly, whack-a-mole.
