Question: Watchguard smtp header problem
I have a Watchguard Firebox 550e running fireware 9.1. I am recieving an error that states “SMTP Headers size is too long” from certain recipients. This error is coming from the SMTP-proxy (incoming) How and where is this setting so I can adjust it?
Solution: Watchguard smtp header problem
Thanks for the assistance. I figured it out. This is fixed in Fireware 9.1.2. I was running 9.1.0
The default SMTP header size is increased from 10,000 to 20,000.
