Question: Watchguard smtp header problem

Hello,
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?

Thanks,

 

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. [22020]
