No email after yum update revisited

[korbynn]

I am missing something and I need help.

I have reinstalled as per:
http://www.howtoforge.com/perfect-se...ispconfig-3-p4
11 Apply Quota Patch To Postfix

postfix is running except that port 25 is now closed.
Therefore no mail is being delivered.

ispconfig 3 monitor states that all is running ok.

Where do I look to find error log or something that will tell me why postfix is not listening to port 25 anymore.

So, after doing a yum update with out excluding postfix,
I rebuilt the postfix code part 10 and 11 of The Perfect Server - CentOS 5.4 x86_64 [ISPConfig 3].

After pulling my hair out and reading alot of posts fixed the configuration problem by doing: php -q update.php in the ispconfig directory.

It seems to work now.

More on this later if there are problems.
