Hi J0den,

 

 

LTM shouldn't be sending any SMTP responses unless you're using an iRule to explicitly do so. Can you capture a tcpdump on the client and server side VLAN(s) and compare the two to see what LTM might be doing when the issue occurs? See SOL411 for details on using tcpdump:

If you need help capturing or analyzing tcpdumps, you can open a case with F5 Support.
