Hi Michael, Thanks for the quick reply, You mentioned :- You mentioned in a previous e-mail that you've changed go.user to RUNMODE=Standalone. Did you also Export this value? Further, did you restart the service after making the change? If you don't Export the value or restart, LISTSERV won't pick up the new value. I added the following to go.user RUNMODE="STANDALONE" export RUNMODE saved it and stop/started listserv server that was last week, but the spamming alerts still keep coming ? Is there something wrong with my interpretation of the commands ?? (I am new to this role, (and unix !) ) rgds
