The SMTP Fixup "feature" also includes several other "features" such as limiting concurrent connections from each external host. This "feature" causes so many problems for anyone with a lot of mail and are also using an external mail spam/virus filtering service because usually tons of mail originates from only a handful of servers, the filtering servers. If anyone has any know how on tweaking Cisco's smtp fixup protocol, that would be great.
