[NAME], just a hunch but can you try and provide the complete path to the blat.exe and see if that works?
Hello, we always use blat.exe to send email notification that we configure at action level in NMC. this works for v19.1.1.1. we upgraded to v19.3.0.4 and we found out that it doesn't work ( FYI the same command when run from CMD of the backup server, it works but from NMC it does not work) it works for v19.4.0.4 it does not with v19.4.0.1  is anyone facing the same problem?
