PROFS: Maximum Allowable Size of Mail Sent Through Gateway

The information in this article applies to:

• Microsoft Mail Gateway to IBM PROFS and OfficeVision, version 3.0

The maximum size of mail items that can be handled by the Microsoft Mail Gateway to IBM PROFS and OfficeVision is dependent only on the storage available on the receiving system.

For host-to-LAN mail, any size of message or file can by accepted by the gateway program on the LAN (HostDisp or VMGATE), provided that there is sufficient disk space on the mail system server to write the associated files. Some network operating systems (such as Novell NetWare) allow LAN administrators to limit the server disk space for specific clients. This should not be done to the gateway PC's network ID.

For LAN-to-Host mail, the maximum message or file size is calculated by the Host Access software. This number is posted on the host session screen, and is viewable when you log on to the gateway VM ID. The LAN gateway program (HostDisp or VMGATE) checks this value before queuing up any mail to send to the host. If the space on the gateway VM ID is not sufficient to handle the mail, it is copied to the VMGATE\ERR directory and the administrator is notified.

NOTE: The PROFS/OV Gtw version 3.4 and 3.4a add the feature to limit the message size that VMGATE.EXE sends from the LAN to VM. Use the command line switch -onnnnnnn. The message size is specified in kilobytes. If a message exceeds this size, the message without the attachments is returned to the sender. You can specify a number from 1 to 2,097,151. For example: to indicate that only messages smaller than 500K can be ent to VM, specify - o500
