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...
