Configure your MTA with a policy rule which says bounce mail where sender address is [EMAIL PROTECTED] but the destination is not [EMAIL PROTECTED] If you are using an MTA which is not sufficiently flexible to achieve this, then install exim :-) If you're only concerned about mail from webmail users, then note that all outgoing mail is sent via the script 'sendit.sh'. You could therefore replace this script with something else which implements your policy for you, e.g. a small perl program. Regards, Brian.
