[qmailtoaster] Reg: rcpthost issue

[Mohankumar]

Hi,  I had one doubt, If i add my local domains in rcpthost file then anybody can telnet my server and by using any of our mail id they can send and receive a fake mail to any of my mail clients, how can i restrict this? If remove the entries from rcpthost file then outside peoples can’t able to send me a mail, it shows 553 sorry, that domain isn't in my list of allowed rcpthosts.   Kindly give me a solution   Regards G.Mohankumar Systems Administrator Altosys Software Technologies Limited 5th Floor, "Pottipati Plaza" No.77, Nungambakkam High Road, Nungambakkam, Chennai- 600 034 Ph: +91-44-28203548/49/51 Extn: 101 Mobile: 09840919355 www.altosys.co.in   +++++++++++++++++++++++++++++++++++++++++++++++++++++++ This e-mail and any attachments may be confidential or legally privileged.
