Same here - we get high CPU on SMTP when there are bad emails in a large batch we send. Sometimes it clears up on its own., sometimes we end and restart SMTP and MSF and it ends

Jeff,
We have seen this happen on client systems. The job in question is the
SMTP server. This could be an indication that a spammer has locked on to
your system and is routing spam through you. Or, it could be that an
email has been sent through your system that has a bad domain name
associated with it. We've seen this drive up SMTP utilization too.
SMTP journalling should help you.

All,
I have a client that is experiencing a high (for them) CPU usage ranging from 40 to 60 %.
They have identified a system job named QTSMTPTCTP as a possible cause.
Does anyone know what this job does? It runs in QSYSWRK and there are about 8 jobs of that name active.
Thanks,
