Back to the top

CAUSE

The Microsoft Mail Gateway to IBM PROFS and OfficeVision sends attachments larger than 32K. However, SoftSwitch cannot process 64K attachments.

Back to the top

RESOLUTION

To limit the size of the attachments sent to SoftSwitch, change all of the LRECL values in the LAN_HOST DATA file on MS-GATE 193 from 65535 (64K - 1) to 32767 (32K - 1).

Back to the top

The IBM PROFS and OfficeVision specification defines 32K attachments. The Microsoft Mail Gateway to IBM PROFS and OfficeVision supports 64K attachments.

The Microsoft Mail Gateway to PROFS Host Access component was written to work the way the PROFS and OfficeVision code works, and supports 64K attachments.

Because SoftSwitch was written to support the PROFS and OfficeVision specification, SoftSwitch cannot process 64K attachments.

Therefore, the size of the attachments sent from PROFS and OfficeVision to SoftSwitch needs to be limited to 32K.
