This is more of an observation than a question.  (and not Spam:)

When setting up our AS/400 for E-mail, it started out as just E-mail using
PPP dialing into our ISP.  the DNS server was on our ISP.  Our network keeps
upgrading to now we have a straight TCP/IP network.  so I can use names for
local machines, I started up DNS serving on the 400.  It go to be we were
running TCP/IP servers for SMTP, POP, DHCP, DNS and all the Client Access
servers.  something I have found is some of the servers on the 400 are
horriable.  namely the DNS server.  it took about 50% of the processor and
DNS lookups took about 30 seconds each.  I moved the DNS server to a FreeBSD
box, and the lookups went to about a second.  Also, the SMTP server.  I
don't know if I had it set up wrong, but there are a few companies like
fedex.com (small companies like that) that I couldn't send E-mail to.  it
would refuse my connection.  I assume since these were all large companies,
they have some sort of spam blocker, and thought I was spam.  so I told the
400's SMTP server that I have a firewall, and send all of my E-mail to my
ISP's e-mail router. and viola, I could send E-mail to everywhere. Has
anyone else had these problems?
