Hi All,

Very intresting problem from my postfix server to BorderWare MXtreme
Mail Firewall SMTP 1)

In some rare case remote smtp server replies: said: 451 Error:
internal error 512 (in reply to end of DATA command))

I think this is bug on BorderWare MXtreme Mail Firewall SMTP server?,
but how to debug the cause of this? How to take packet trace from this
message that fails?

Well, Borderware box is not mine, but looks like it's running buggy software ..
