If e-mail is sent, true/false variable

Hello,

Can someone cook me a quick script that does the following:

If

"/tool e-mail send to=me@me.com body="$strName Logs for $strDate" subject="$strName Logs for $strDate $strTime" file=log"

is sent successfully, then do:

/file remove log
log info message="Logs successfully sent via e-mail!"

else

log info message="Could not connect to SMTP server!"

Having trouble figuring out how to validate the /tool e-mail send command…
Also a delayed loop will be nice if the email could not be sent, let’s say 5 minutes…

I have used email for a long time (gmail) and never missed an email, so I do not see the need for testing it.
Not sure if and how Router would log this.
