Hello, I successfully installed ISPConfig using Falko's Fabulous Installing a LAMP system With Fedora Core 6 Falko's Fabulous Installing a LAMP system With Fedora Core 6 I'm having a hard time getting the SMTP server to only send mails from an authenticated user. Right now with the basic setup you can send mail from a client with any user name on the same subnet. I setup my Eudora client with a username [email protected] (not a user) and sent mail to my yahoo account and it sent without a problem. What exactly do I need to change to only let authenticated users send mail on the outgoing SMTP server requiring them to authenticate with their login and password I set up for them in ISPConfig? And if I only allow authenticated users to send e-mail in this fashion will this affect any internal processes of the server? Thanks, George
Please add / edit this lines in your main.cf: Code: mynetworks = 127.0.0.0/8 smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination The line allows sending for local processes without password which is nescessary . Everyone else will be forced to authenticate.
Internal user authentication I'm using Ispconfig 2 on a suse 11 installation. I have added the suggested lines mynetworks = 127.0.0.0/8 smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination My mail server is not an open relay, and users have to authenticate except when sending to an internal user. So anyone using my smtp server can send an email to any user @mydomain without any authentication. Can I limit this or is that a part of normal mail server operation. The problem of course is spam . I'm using spamassasin, but a lot of spam still get's delivered. Thnx
This is the normal bahaviour of every mailserver. If you would limit this, you would have to call everyone that wants to send you an email and tell him his password before he is able to send you a mail which is a bit impractible... If spam mails shall be deleted then select the delete option in the spamfilter settings of the email account.
