Send Large E-mails in One Piece

Hey, David:

Is there a limit on the size of an attachment to an e-mail sent using the Send Distribution (SNDDST) command?

For example, a simple sales report for a week (about 50 pages) will route through our exchange server and arrive with the attachment I specify (report.txt) but the same report run for a month (85 pages) arrives in my e-mail with the attachment, report.txt.dat.

The default behavior for the OS/400 POP mail server is to split large e-mails. Sending a large e-mail to a mail client that cannot handle large e-mails causes problems.

On the other hand, sending two or three partial e-mails to clients that cannot put them back together causes other problems.

Greg, the way to turn off e-mail splitting depends on release. On V4R4 and above, use Change POP Mail Server Attributes (CHGPOPA) to set MSGSPLIT to *NOMAX.

On V3R2, V3R7, and V4 releases that do not support *NOMAX you can create a single character data area in QUSRSYS named QTMSNOSPLT.

On V3R2 and V3R7, install the following PTF's.

V3R2	SF42422
V3R7	SF37157

You must end and restart the POP server for the change to take effect.

If the data area exists, mail will not be split. You can turn splitting on by deleting the data area.
