HP doesn't make a lot of noise in the free software world, even if it is an actor and also a user for its own IT infrastructure.
For example, all the incoming mail in HP goes through
PostFix
servers
# dig hp.com -t mx | grep MX
;; hp.com, type = MX, class = IN
hp.com. 21m28s IN MX 50 cossmtp.hp.com.
hp.com. 21m28s IN MX 50 palsmtp.hp.com.
hp.com. 21m28s IN MX 20 postal.agilent.com.
hp.com. 21m28s IN MX 10 envelope.hp.com.
hp.com. 21m28s IN MX 10 letter.hp.com.
