We only want to install postfix as a null client for sending alerts from our
servers. When I try to install postfix, it wants to install
mysql-libs-5.1.61-1.el6_2.1 as well. I'm afraid this will break our mysql
servers, which are all running MySQL 5.0.77. Will installing postfix break
things? I

I just didn't know whether postfix has any of its own special logfiles
outside of the standard two I would normally think to check (messages
and maillog). Thanks for your help, though.

You're right, I misunderstood the man page. I changed it as you
suggested and now it's working. Thanks!
Now here's a related question. When I receive the alerts on my cell
phone, the 'From' field just says 'root'. Is there a way t
Sahil,
The remote mail server is reporting this error:
450 4.1.8 : Sender address rejected: Domain not
found
So I added the following line to main.cf and restarted postfix:
masquerade_domains = lb01.domain.com domain.com
But it did not help.

I was afraid that if I admitted not knowing which logs were relevant,

/var/log/messages. Are there others?

Forgot about that part. I will check into it, but it seems to me that it
isn't necessary in this case because the mail is being sent correctly

It's not invalid, it's just unknown to the receiving mail server because
there is no reverse DNS for it, which is by design. It's an internal
machine and there should be no reverse DNS for it
On my postfix server, when I send to outside users using the 'mail'
command, the remote mail server rejects the messages with an 'unknown
domain' error because they are coming from r...@host.domain.com.
However, if I telnet to postfix locally and submit the message using
