Hi, usually you should set up your Mailserver in a way, accepting Mail from any for your domain only and sending Mail to any from your Network only. If you are using Check Point SMTP Ressource, you should never configure in the Matching Tab Sender "*" in combination with Recepient "*" and a rule with "any any SMTP-Res. accept". Just define two resources, one for incoming mail (Rec *@mydomain) and one for outgoing (Sender *@mydomain). Combining this with correct rules will prohibit Mail-Relaying also. Hope it helps, best regards, Matthias http://www.fw-1.de -- AERAsec Network Services and Security GmbH Wagenberger Straße 1 D-85662 Hohenbrunn, Germany http://www.aerasec.de ================================================= To set vacation, Out Of Office, or away messages, send an email to [email protected] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [email protected] =================================================
