[c-nsp] Cisco 7301 IPS Issue

[Nick Kassel]

Yesterday evening we upgraded our BGP routers to Cisco 7301 with IOS
c7301-advipservicesk9-mz.124-9.T. We enabled the IPS signatures to log
only, however we had an issue with incoming web mail from Yahoo and
Hotmail, all other e-mail was fine including other web mail such as
googlemail. After checking the signatures we could not see any that may
cause an issue and especially as all signatures are set to alert and not
block, however as soon as we disabled the IPS all the web mail was
delivered. I was wondering if anyone may have come across this issue or
anything similar before.

 

Any help would be greatly appreciated.
