I encounter the same problem with Evo && OutLook server, especially
while moving in UMTS (WAN) networks or even between WLAN's in our
building. The problem is that Evo helds permanent connections to the
servers:

$ netstat -an | fgrep EST | fgrep ...
tcp4       0      0 192.168.13.128.39397   xxx.174.29.60.3268 ESTABLISHED
tcp4       0      0 192.168.13.128.55806   xxx.174.29.60.3268 ESTABLISHED
tcp4       0      0 192.168.13.128.18739   xxx.174.1.144.443  ESTABLISHED

and does not use somekind of polling, like with POP or IMAP. Seems to be
a design problem (or feature :-))
