Multiple spams _sent by_ MessageLabs, or multiple spams that they did not 
catch and block? If the latter, that's no reason not to add them to 

trusted_networks is for hosts you trust not to forge headers, not for 
hosts you trust not to originate or forward spam. I don't think 
MessageLabs would forge headers on mail they process for you under 

I apologize for my earlier suggestion, it was off-the-cuff; yes, if you 
use MessageLabs to process your inbound mail it does make sense to extend 
trust to them so that you do DNSBL and other checks on the host that 
delivers mail _to them_ rather than performing those checks against the 
MessageLabs hosts.
