"This option will help prevent the most common form of spam abuse on a server that bypasses exim and sends spam directly out through port 25. Enabling this option will prevent any web script from sending out using socket connection, such scripts should use the exim or sendmail binary instead"

| If you set SMTP_BLOCK = 1 then you should also set SMTP_ALLOWLOCAL = 1 or your webmail clients won't be able to send any mail. SMTP_ALLOWLOCAL is the option directly underneith SMTP_BLOCK.
