Ok, ok. Also historisch. Ist das auf der Büchse schon mal gelaufen oder ist das Fehlerlose Programm auf einer älteren gelaufen??

Ich würde mal folgendes probieren. Auch wenn im ersten Augenblick kein Zusammenhang zu bestehen scheint, fixt diese Vorgehensweise mehrere Probleme mit dem SNDDST.
Wenn das nix bringt versuchen wir den MSF auf die Reihe zu bekommen. Der könnte es auch noch sein. Aber immer eins nach dem Anderen:

Document Title
SMTP Warm and Cold Start

Document Description
During SMTP start-up, SMTP may destroy distributions that it cannot process. How SMTP does this depends on the existence and contents of a single-character, user-defined data area called QTMSCLEAN in the QUSRSYS library. The character in this data area indicates the extent of mail control block clean-up:

o An uppercase or lowercase c in this data area indicates a cold start was requested to free all mail control blocks.
o Any other character causes a warm start to free only the first floater mail control block found. A floater is an MCB that was dequeued but was not fully processed or failed processing when SMTP ended (for whatever reason).

When SMTP starts, a recovery function checks the QUSRSYS library for this data area and proceeds accordingly.

Since a warm start frees only a single MCB, it may be necessary to stop SMTP, create the data area, and start SMTP more than one time to get to the MCB that is causing the problem. If there are a large number of MCBs, a cold start may be the fastest way to correct the problem.

To create the QTMSCLEAN data area, use the Create Data Area (CRTDTAARA) command.

Cold Start: The following command causes a cold start to occur and frees all the mail control blocks found the next time SMTP starts up.

On the OS/400 command line, type the following:

Important Note: When a cold start occurs, all unprocessed SMTP distributions found in the system are destroyed and mail is lost.

CRTDTAARA DTAARA(QUSRSYS/QTMSCLEAN) TYPE(*CHAR) +
LEN(1) VALUE('c') AUT(*ALL)

Press the Enter key.

Warm Start

To cause a warm start and free only the first floater mail control block found the next time SMTP starts up, on the OS/400 command line type the following:

CRTDTAARA DTAARA(QUSRSYS/QTMSCLEAN) TYPE(*CHAR) +
LEN(1) VALUE('W') AUT(*ALL)

Press the Enter key. Once the clean-up is complete, code within SMTP deletes the QTMSCLEAN data area from library QUSRSYS (provided the data area was created using the *ALL authority).
