I have a Cisco ASA 5510 firewall and my company uses a third party POP3 providor for email.
I have just installed a Konica Multi-purpose copier that can scan a document and email it. However, when I do this, my firewall stops it with the message:
Dropping TCP packet from inside:10.203.15.202/1025 to outside:18.104.22.168/25, reason: MSS exceeded, MSS 1380, data 1460
I have seen how I can configure MSS to exceed for traffic coming in, but how can I configure it for traffic going out
