If those are internal hosts, it could be a DNS issue.  If they are 
external, your provider could be blocking these.  From the commandline 
on the N900, install telnet and try 'telnet smtp.mymailserver.tld 25' 
and see if you get a version string from the server.

Was the wifi card in monitor mode?  Was it set to the correct channel? 
With WEP and WPA you won't be able to see IP addresses unless you give 
WS the info needed to decrypt the traffic.

It may be easier to install tcpdump on the N900 and sniff wlan0, 
transfer the file to a machine with WS and analyze there.

That's the best part of the troubleshooting process, coffee.  ;-)
