smtp authentication problem
Hi all,
I'm using postfix server on fc8.I implemented smtp authentiction on postfix server.I googled and i followed these steps. Edit /etc/postfix/main.cf, find the keys below and change its values as follows or add it at the bottom of the file. mynetworks = 192.168.0.10, 192.168.0.13, 192.168.0.18, 192.168.0.22 127.0.0.0/8 smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination broken_sasl_auth_clients = yes After this i restarted postfix server. Then I logged from other network with my ip from out look express with out user account and password, i've sent a mail to my mail id. I was able to receive the mail. For the first time its asking for username and password there i've entered my user name and password, then i logged out. After half an hour i again tried its not asking for username and password, its directly sending the mail. How can restrict this & how can i enable the authentication process. Can any one suggest me. Thanks in advance... |
It is possible that you are sending from a host in one of these network ranges 192.168.0.10, 192.168.0.13, 192.168.0.18, 192.168.0.22 127.0.0.0/8.
Those hosts are allowed to relay mail without authentication. |
Hi,
I'm not sending mail from the 192.168.0.10,192.168.0.13,192.168.0.18,192.168.0.22,127.0.0.0/8 these networks, i've sent the message from the other network its not in the above range, its totally different. |
Oh just seen something from your post, if you send mail to yourself from anywhere you will be able to receive it.

Hi datopdog,
when i was trying to send a mail from other network,i was able to send mail with out login any user account. Even my mail server also receiving mail without asking authentication. How can resolve this. |
are you able to send mail to email addresses that are not hosted by the server (in other words relaying) without authentication ? Can you send to a gmail address for example without authentication ?
