      Please let me know what I am missing? NIS domain name? how to set up this. Thanks a lot!!!

      I set up the postfix for evaluation purpose, so i could be used inter-company and later be link to outside. but I need to show my boss it's full features. Thanks!

          SASL login authentication failed: no mechanism available
          Please show /etc/postfix/sasl/smtpd.conf

          You might want to verify you have set "pwcheck_method: saslauthd" and that the saslauthd daemon is running.

          /sbin/chkconfig --level 345 saslauthd on
          sbin/service saslauthd start

          Edit /etc/sysconfig/saslauthd and verify "MECH=pam"

          Restart Postfix: /sbin/service postfix restart

          Btw, if you are looking for a reliable email system that has all the features one can possibly imagine plus a web interface for the complete administration and use, and easy installation and administration, then check out Communigate Pro. You will need a small budget to buy the product, but you can download a demo version for free. I used it a couple of years go in all sorts of configurations and different platforms and I was very happy with it. For example, I used it on a small 500 Mhz Server as an smtp-relay and front-end filtering system and it processed about 30'000 emails daily without a problem, including defeating constant spam attacks.

            my setting as below:

            but I have followed the instruction and set it in /usr/local/lib/sasl2/smtpd.conf:

            *******Edit /etc/sysconfig/saslauthd and verify "MECH=pam"
            [root@mail postfix]# cat /etc/sysconfig/saslauthd
            # Directory in which to place saslauthd's listening socket, pid file, and so
            # on. This directory must already exist.

            # Mechanism to use when checking passwords. Run "saslauthd -v" to get a list
            # of which mechanism your installation was compiled with the ablity to use.

            # Additional flags to pass to saslauthd on the command line. See saslauthd(8)
            # for the list of accepted flags.


            by the way, how to buy the solusion you mentioned? Thanks!!!!

            also I have put the following lines in /etc/postfix/main.cf as:

            smtpd_sasl_auth_enable = yes
            smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination,reject_non_fqdn_recipient
            smtpd_sasl_application_name = smtpd

            My plateform is X64 intel and installed Oracle Linux 5.7

            • 3. Re: postfix authentication verification is failure
              Here is another link, perhaps you will find some solution there: http://www.postfix.org/SASL_README.html

              Regarding the other product: http://www.communigate.com. From what I understand, there is a free "trial" and "community" version. The "community" version only allows up to 5 mail accounts and will stop working if you exceed that limit. The "trial" version does not have any limitations, but will add a "Communigate Pro" text banner to every processed mail. Honestly, this product would be my first choice for setting up any mail system of any size, not only because I have very good experience with the product for 10 years, but also because you get quick results and it can simply do everything. There might be some learning curve and familiarizing necessary when using advanced feature, but like with sophisticated product, which doesn't? It isn't the cheapest product if you decide to buy a license, but at the end, you will spend less time and troubleshooting and you can rely on it. The product also runs an any computer platform and OS that is worth mentioning.
