I have noticed looping and memory-leaking with 2.99.52patch1.
(Intel, RedHat 6.1, 2.2.12 machine)
In some loops the receiver had been flooded with mail.
I think smtpserver loops and leaks some, too.

Right now I am testing 2.99.53
(Intel, RedHat 6.2, 2.4.0test3 machine).
Smtp loops in MX-lookup on hosts in the local domain, and I have not
figured out why (host gets an authorative reply)
