Network Interactionativity

For some reason, on certain access points at LCA - for instance the one in the St. Mary's common room - I need to set my MTU to 1000 (i.e. down from 1500) in order to get Thunderbird to do secure POP. Everything else works fine, but Thunderbird just sits there timing out. I discovered this by watching the Wireshark log and noticing packet fragments disappearing (i.e. some packets where the tcp fragment analysis couldn't find parts of the packet to reassemble). Hopefully this isn't also causing Steve Walsh to pick up his specially sharpened LAN cable and hunt me down...
