We don't know that.
We know that _one_ of _a_ pool of three IOL mailservers wouldn't accept
mail from _one_ of _a_ pool of twelve Eircom mailservers. Beyond this
is speculation. It is not uncommon for one server from a pool (ie., of
outgoing mail relays) to be blacklisted.
We also know that SpamCop is not currently blacklisting the particular

It might be worth investigating using SpamCop, or some other RBL, in
conjunction with another mail filter. For example, SpamAssassin can use
SpamCop (and other RBL's ?) to add hits to an incoming mail, which might
be better than having your MTA reject SpamCop-listed senders. I'm sure
you'd get twice as many opinions on this as there are possible setups
