I do agree with your statement that a mail server
sold on the ISP market should not crash if the
admin of one virtual domain creates a mail loop.
As a general design rule, all software should protect
itself against bad user input. Either ignore it or try
to process data as gracefully as possible.
The 50 user limit on aliases is another example. If
Imail can not handle aliases with over 50 users,
instead of going into long delivery delays it should
either:
1. Bounce any message to the suspect alias sending
the moderator a message indicating "Too many
addresses on alias".
2. Forward the message and list to the list manager for
processing.
Having to tell domain admins to limit their list aliases
to 50 and that if they go over 50 they must convert to
a list sounds too manual for software used in the year
2000. None of the screens tell you whether you reached
the "magic" number so an admin must count each address
to check whether they reached 50.

Subject: RE: [IMail Forum] setflags - Set Imail user flags from the command
line - IpSwitch, what gives here?
Yeeee Haw! It's amazing that IPSwitch can't produce these little utilities.
I just got off the phone with IPSwitch tech support about a SMTP32.EXE Dr.
Watson error we're having. They just told me, and I quote:
"Go through every alias/list, and make sure you don't have any mail loops".
I know it's not the support Reps fault, but come on. They don't admit this
is a bug, rather an incorrectly configured mail system. No matter how ANY
of our users configure their boxes/domains, it should NOT bring our entire
mail system to a screeching halt. Back to the subject, Keep in mind, on
this particular IMail installation, we have about 700 Domains, and thousands
upon thousands of Lists/Aliases. They said it's not a Bug in IMail, and
it's a user-end problem. How does that make all you Admins feel, that any
of your Host Admins can create two aliases that point to each-other, and
crash your entire Mail system. Yet, it's not a bug. Wonderful.
Check out this quote on their site:
"IMail delivers greater performance than proprietary mail systems, offering
scalability to over 100,000 accounts on a single server"
Yea right, then you have a problem and call Tech support and they tell you
"Sir, you need to go through each account manually to detect which user
created an alias loop. It's not our problem."
It would be nice to hear IPSwitch say "Yes, we know about it. We have our
developers looking into that problem, and we have it marked as an urgent
bug. We should have it fixed shortly".
Can anybody recommend a mail system that can take abuse from users and still
run?
