I have upgraded my Postfix MTA and after upgrade the post got broken. When I try to send mail from webmail , following error pop’s up.

Quote:

Error connecting to localhost - Check the hostname resolves, accepts incoming SMTP connections and is active.

Does any one have such problem with postfix.

How have you upgraded the postfix in server; is it through YUM or through source?

I am not good with source installation, so I use yum to update postfix.

It seems the upgrade of post fix has overwritten the master.cf file in post fix and removed the smtp binding entry from master.cf.

To fix the error you need to open the /etc/postfix/master.cf, and add the following lines in the end of /etc/postfix/master.cf.

smtp inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025
smtps inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 -o smtpd_tls_wrappermode=yes
