The following appeared on CE's support forum on Compuserve earlier this month:

"Both QuickMail and Ethernet cards in an SE or SE/30 (This only applies to 
SERVERS)  run at interrupt level.  This means that either will interrupt 
the machines processing at any time in order to do what is necessary for 
its operation.

The conflict comes when both try to do their normal operations at the same 
time.  The result is that they battle each other for control until the 
server crashes.

As to when the server crashes is directly related to the amount of traffic 
on the network, particularly at the time just before the crash.  Larger 
networks with high traffic tend to crash quite frequently and smaller 
networks with lower levels of traffic tend to crash less often. The 
worst-case scenario is that the server will crash a few seconds after 
booting or not boot at all, while the best case seems to be normal 
operation for a few days.

The above scenario only applies to SE and SE/30 SERVERS.  It does not 
apply to  the Mac II, Mac IIcx, Mac IIci, Mac IIx and Mac IIfx, nor does 
it apply to workstation machines using Ethernet.

CE Software's recommendation is that in order to run QuickMail on an 
Ethernet equipped server that the server be a Mac II class machine.  
(Since speed is usually a main issue in deciding to go with Ethernet in 
many cases, the network will benefit from a server machine, in most cases, 
that is faster than an SE/30)
