However, in these days of anti-relaying and anti-spamming it depends on how they have their mail server configured. If they're running sendmail and they've used one of the features promiscuous_relay, relay_based_on_MX you should be fine (mind you, I wouldn't trust someone running a box with promiscuous_relay, but it's your call). If they don't have one of those features then they'll need to set your domain as one permitted to be relayed through their server. And if they're running something other than Sendmail, they'll have to do whatever the equivalent thing is for their software.
