Resolving The Problem

This document provides information needed for e-mail issues.

Important Note: In order to debug e-mail issues, an SMTP trace is needed. When using SNDDST to send the mail, an MSF dump may also be needed.

TRCTCPAPP is the command used to initialize the SMTP client and server traces which we need to debug SMTP.

Step 1.	End SMTP if started. *ENDTCPSVR SMTP.**
Step 2.	To start the SMTP Flight Recorders for Outbound Mail, on the operating system command line type the following: *TRCTCPAPP APP(SMTPCLT) TRCFULL(STOPTRC)* Press the Enter key. To start the SMTP Flight Recorders for Inbound Mail, on the operating system command line type the following: *TRCTCPAPP APP(SMTPSVR) TRCFULL(STOPTRC)* Press the Enter key. Start SMTP with the following commands: *STRTCPSVR SMTP**
Step 3.	Run the test scenario causing the issue.
Step 4.	To stop the SMTP Flight Recorders for Outbound Mail, on the operating system command line type the following: *TRCTCPAPP APP(SMTPCLT) SET(OFF) TITLE('Outbound E-mail')* Press the Enter key. To stop the SMTP Flight Recorders for Inbound Mail, on the operating system command line type the following: *TRCTCPAPP APP(SMTPSVR) SET(OFF) TITLE('In-Bound E-Mail')* Press the Enter key.
Step 5.	On the operating system command line, type the following: WRKSPLF Press the Enter key. One or more spooled files is generated that contain the needed traces.

If you are having difficulties with the SNDDST command, an MSF dump is needed if MSF is not handing the mail off to SMTP. The following steps will get the MSF dump for debug.

Step 1.	On the operating system command line, type the following: CALL QCMD Press the Enter key. Note: This starts the Command Line Screen. To exit the Command Line Screen, Press the F12 function key. On the operating system command line, type the following: ADDEXITPGM EXITPNT(QIBM_QZMFMSF_ACT) FORMAT(MSFF0100) PGMNBR(200) PGM(QSYS/QZMFDUMP) TEXT('MSF Snap-in') *PGMDTA(JOB 12 SPCL01009999)** Press the Enter key.
Step 2.	On the operating system command line, type the following: ENDMSF Press the Enter key.
Step 3.	On the operating system command line, type the following: *STRMSF RESET** Press the Enter key.
Step 4.	Run the test scenario causing the issue.
Step 5.	Remove the MSF Snap-in.
Step 5a.	On the operating system command line, type the following: WRKREGINF QIBM_QZMFMSF* Press the Enter key.
Step 5b.	Select: 8 QIBM_QZMFMSF_ACT Press the Enter key.
Step 5c.	Select: 4 200 QZMFDUMP QSYS Press the Enter key.
Step 5d.	On the operating system command line, type the following: ENDMSF Press the Enter key.
Step 5e.	On the operating system command line, type the following: *STRMSF RESET Example: WRKSPLF SELECT(QMSF)** Press the Enter key. Look for spooled file QPSRVDMP.
