Help With Intranet Configuration

2010-01-04T23:06:29Z

Hello all,
I have a server running on a local intranet that I would like to
receive email on for a web application. The server's hostname is in
the form of hostname.example.com and I'm simply trying to receive
email for local accounts on the server. I've tried configuring main.cf

Messages sent with Postfix have attachment?

2010-01-04T10:41:58Z

All of the messages I send via SMTP through Postfix come into my inbox
(Yahoo) showing an attachment, but there is nothing there.
The header shows:
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="----
=_Part_124_68713.1262601356866 "
Does anyone have an idea as to what might be causing this phantom

And of course, there's also this port 587 option, but I really don't
know which is better or worse to use in my case :\

I should also add, that when trying to send over port 25 with TLS, I
get the following from my client:
"ERROR","web-0","01/03/2010"," 06:55","mail spooler","Exception reading
response;
nested exception is:
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext
connection?"

Being new to Postfix, I'm looking for suggestions. I keep reading
about how things "used" to be on smtps using port 465, but now they
aren't. It's all a bit confusing. I've read 200 sites tonight alone.
Assuming I have a server that needs to send mail (such as PHP, Ruby,
ColdFusion, etc), what is the best configuration?

Postfix port 465 /TLS problem

2010-01-03T14:30:31Z

I have been wrestling with Postfix for a couple of days now and am
having some minor issues with TLS and secure ports.
First, here is what IS working....

Email svc providers

2009-12-27T21:40:25Z

I am currently consulting for a small retailer. They have been using
an online email service provider for the past few years to blast
personalized emails to their customers (opt-in, and 100-200 thousand
emails at a time). They have asked me to see if we can install an
email server in house to accomplish the same thing and eliminate the

Preventing Postfix from _sending_ backscatter

2009-12-14T12:12:36Z

Hi
We run a Postfix server which handles email for a number of our
customers domains. Most have mailboxes on the server, which all works
fine, but the problem is for domains where the mail is forwarded to
another server. This can cause our server to generate backscatter,
which I would like to stop.
The problem happens when a piece of spam is sent to

Multiple IPs for postfix

search.

Wow. I was just struggling with the exact same problem. I was
watching extra debugging on qmgr, watching sql queries in mysql's
query log, going over my main.cf again and again looking for a mistake
and just couldn't find anything.
Like you, I'd simply moved a working set of config files from a test

This weekend, I essentially gave up on trying to find the solution for
free, and posted my problem on Experts-Exchange.com. After a few days,
I finally found the solution (via a response, of course).
It seemed that the following configuration line was the culprit in my
case:
