This article was previously published under Q137998
SYMPTOMS
Messages sent from a Microsoft Exchange Server to a Microsoft Mail for
AppleTalk Networks server via the MS Mail Connector (AppleTalk) MTA are not
always processed in first-in, first-out (FIFO) order.
CAUSE
This is by product design.
MORE INFORMATION
If gateway traffic is high and the Macintosh blocking factor (the number of
messages processed by the Macintosh component each cycle) is set to a low
value, the Exchange Server can backfill the gateway queue while the
Macintosh gateway component processes the first group of incoming messages.
Messages then placed in the queue by the Exchange Server can be processed
ahead of messages handled during the previous cycle. This behavior can
continue until the backfilling ceases.
Administrators can reduce this behavior by running the Macintosh Mail
client against the gateway Macintosh server as Network Manager and raise
the blocking factor on Mail menu, by choosing Gateway, Configuration.
