- Microsoft Mail Gateway to X.400 3.2
This article was previously published under Q102746
SUMMARY
Version 3.2 of Microsoft Mail Gateway to X.400 performs three mail exchange processes:
- It receives inbound messages sent from X.400 systems to Microsoft Mail for PC Networks postoffices, and it receives outbound messages sent from Microsoft Mail postoffices to X.400 systems.
- It routes messages and queues them for a specific X.400 message transfer agent (MTA) or for a Microsoft Mail postoffice.
- It transmits outbound messages to remote X.400 MTAs and delivers inbound messages to Microsoft Mail postoffices.
If the X.400 Gateway MTA fails to connect to another X.400 MTA, it continues trying to make the connection until it is successful or until the message time-out period expires. The interval between attempts grows exponentially to a maximum of 24 hours.
Here is an example of exponential growth of the interval between attempts:
Failure Number Time to Wait
-------------------------------------------------------------------
1 1 minute
2 5 minutes
3 15 minutes
4 60 minutes
5 2 hours
6 3 hours
7 6 hours
8 12 hours
... ...
N 24 hours
MORE INFORMATION
If an incoming connection is established between the X.400 Gateway MTA and an external X.400 MTA it has been trying to connect to, the X.400 Gateway MTA attempts an outgoing connection immediately after processing the incoming mail.
You can set the time-out period in the X.400 Administrator program (X400ADM.EXE) in the X.400 Profile section, under Message Timeout.
Here are the default message time-out periods:
Microsoft X.400 Default
Mail Priority Mail Priority Time-Out Period
-------------------------------------------------------------------
Normal Normal 24 hours
Low Non-urgent 36 hours
High Urgent 45 minutes
