Argh. So, we're staying at the XV Beacon, a nice hotel at the top of Beacon Hill. One attraction was the in-room broadband. Works pretty well for web access and for retrieving email. However, their ISP apparently redirects outbound port 25 to their email server (perhaps to make it easier for people to relay mail otu without changing settings). However it doesn't work, all attempts bounce. Argh. Double argh.
