Increase in SMTP connections?

Any large-ish mail-receiving sites[1] seeing an increase in SMTP
  connections this week? I'm not necessarially talking about
  messages here, just connections. If so, please contact me
  off-list. Thanks.

Should we include rejected connections and spam dropped on the floor in the
count? :slight_smile: (Not that it matters in our case, as it moves us from some small
millions to some larger millions, and still lacking a zero or two...)
