Do you allow any user to send mail as any user, without need of authentication on your mailserver? Even if you run their mailboxes/addresses? Do they all have static IP addresses or do you imply allow users from dynamic addresses to send mail directly? -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
