There must be something useful here…

At this point I feel very confident with the inner workings of IspCP.  I have modified suexec, postfix, and other core stuff.  In the process I have started to learn Apache2′s inner workings as well.  Today I am going to talk about issues with Postfix.  The issue is that a Ubuntu installs PostFix with a LAMP install, and IspCP has some custom configs to make it work.  YesterdayI thought I was smart enough to make modifications to the master.cf and main.cf.  Wow was I wrong.  After the changes I made, when you would telnet to port 25 (587 too) it would give you a blank screen and would just hang.  When I looked at the logs all i got was:

Jan 30 06:34:56 [host]postfix/master[28195]: warning: process /usr/lib/postfix/smtpd pid 4838 exit status 1
Jan 30 06:34:56 [host]postfix/master[28195]: warning: /usr/lib/postfix/smtpd: bad command startup — throttling
Jan 30 06:35:56 [host]postfix/smtpd[4876]: fatal: dict_open: unsupported dictionary type: inet:  Is the postfix-inet package installed?

From the error, it would seem that I am missing a package for postfix.  Not the case, in-fact that package doesn’t exist.  Why would they reference a package that doesn’t exist?  I was able to bring the whole thing back up by restoring the master.cf and main.cf from the /etc/ispcp/postfix/working/ directory.  When in doubt, return to the default config file and start over.
