Dear all,
I also having problem to block email spamming. In my mch RH6.2 with
sendmail-8.9.3-20, I found that it only work for
/etc/mail/ip_allow
which means all the ip address in ip_allow will allow to use the smpt
service, if an ip is not specified in ip_allow, it will show the
following error message... (but b4, this step, do we need to change any
setting in sendmail.cf file? cause I not sure which is the once add-on
to it, I used the linuxconf - basic sendmail configuration - Enable
relay control (spammers), without this setting ip_allow doesn't work too...)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The message could not be sent because one of the recipients was rejected
by the server. The rejected e-mail address was '[EMAIL PROTECTED]'.
Subject 'test', Account: '127.0.0.1', Server: '203.127.111.78',
Protocol: SMTP, Server Response: '551 we do not relay', Port: 25,
Secure(SSL): No, Server Error: 551, Error Number: 0x800CCC79
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
but when tried on access file with the proper procedures to create the
access.db file, it doesn't take any effect? so how to get access setting
work with sendmail? can we specify a network address in ip_allow?
any advise are welcome and many thanks for all help.....
best rdgs,
gary
