This is likely the SMTP mailhost changing/altering the username.
However, you can configure SMail to do/look like anything basically.
If I use my CA Mail account, as an example - no matter what I set it to - the SMTP host sets the from address to be my CA email address.
However, if I use an account that I (am pretty sure) doesn't exist - I can make it look how I want.

How it looks in email:
The key here is the "-f" option.
You can include this in the SetScript to override the from.
1. Open the $SPECROOT/Notifier/SetScript in a text editor
2. Find this line:
$MAIL -s "A $SEV alarm has occurred on $SERVER (Model Name=$MNAME)(Model Type=$MTYPE)" $RCVRS < /tmp/set_alarm.$PID
Change to:
$MAIL -f "Name Here" -s "A $SEV alarm has occurred on $SERVER (Model Name=$MNAME)(Model Type=$MTYPE)" $RCVRS < /tmp/set_alarm.$PID
3. Save the file and restart Notifier.
