Dave, This does not answer your question, but it appears from the error messages that you are still running the older zOS SMTP task. ZOS Communication Server now provides a new CSSMTP task, which no longer copies the spool files to sequential dataset and plays the dataset "rename" game. SMTP is going to be dropped from support soon ( after zOS V2.2 ??) We use to see errors like these from time to time, but they have disappeared since migrated to CSSMTP.

[[ SEI WARNING *** This email was sent from an external source. Do not open attachments or click on links from unknown or suspicious senders. *** ]] Is there a way to determine if and how much a VTOCIX is fragmented. Way back when (when disk wasn't quite so cheap), we standardized on parking the VTOCIX in the 14 tracks left in the 1st cylinder, and for a Mod-3, VTOC of 105 tracks (7CYL) immediately following, and usually a 2 CYL VVDS right after that. Most of my SMS managed application disks still follow this. And it worked well for many years. But, during high volumes of SMTP activity, I have begun to get: IEC603I VTOC ERRORS MAY EXIST ON C465,PPRD22,8,027 IEC331I 042-002(0812041B),SMTP ,SMTP ,RNAM,IGG0CLH2 IEC331I VOL,PPRD22,NAME,SMTP.CONN257.NOTE IGD17003I PERMANENT I/O ERROR ON VOLUME PPRD22 139 FOR DATA SET SMTP.CONN257.NOTE HISTORIC RETURN CODE IS 8 DADSM DIAGNOSTIC INFORMATION IS 0812041B IGD306I UNEXPECTED ERROR DURING IGGDAR02 PROCESSING 140 RETURN CODE 8 REASON CODE 27 THE MODULE THAT DETECTED THE ERROR IS IGDVTSDA SMS MODULE TRACE BACK - VTSDA VTSCU VTSCT VTSRN SSIRT SYMPTOM RECORD CREATED, PROBLEM ID IS IGD00898 IEC614I RENAME FAILED - RC 008, DIAGNOSTIC INFORMATION IS (0812041B), 141 SMTP,PPRD22,SMTP.CONN257.NOTE EZA5544E Unable to RENAME file SMTP.CONN257.NOTE to SMTP.A0258454.NOTE rc=408 EZA5568E UNABLE TO ALLOCATE ADDRBLOK DATA SET CORRECTLY SMTP is playing a dataset rename game - SMTP.TEMP.NOTE to SMTP.CONNnnn.NOTE (a 3 character length increase) SMTP then kindly sends a blank email to the recipient which then gets reported as suspicious :) I don't remember how we reached the numbers we used, but looking at the info the ICKDSF manual, the 14 track index should be large enough for the 5250 datasets possible with a 105 track VTOC. I an wondering if I can REFORMAT REFVTOC EXTINDEX(14) and get refreshed, unfragmented VTOCIX.
