I am running an Alpha 4610 with Digital Unix 3.2 and Sendmail 5.65
When an address of the form user%host1_at_host2 is sent to the system, Sendmail 
produces the following error:
Mail From:user%host1_at_host2
554 rewrite: cannot prescan new hostname: host1<_at_host2.sps.mot.com
554 user%host1_at_host2... Unbalanced '<'
554 rewrite: cannot prescan new hostname: host1<_at_host2.sps.mot.com
I have checked out the rewrite rules in debug mode but I do not see anything 
wrong.  I am using all default rules.
The same address sent to my Sun and HP systems resolves OK.
Any ideas/solutions?
Regards,
Len
