Hrmm. I don't have access to change the MTU on this VPS (bah), but the
MTU is already set to 1000. What did you set your MTU to? I think 1000
is probably fine for MTU, so I expect there's something else going on.

On a related note though, does anybody know how to change the MTU on a
Windows machine? I get the feeling that the admin on the other side (on
Exchange) isn't too technical when it comes to managing an MTA.
