Centos, Fetchmail, Postfix, Open Exchange = Weird Mail behaviour

bugg_tb · 02-12-2007, 08:09 AM

Hi Guys,

I'm playing around with open exchange(using the ava-sbs script), and I want it to fetch my email from my isp pop3 account so in my users root dir I've added,

Code:

poll mail.wamonline.org.uk
        proto pop3
        user "tom@wamonline.org.uk"
        pass "*******"
        is bugg

which downloads all the mail, and seems to work fine,

but once its downloaded it shunts them off to postfix(is this normal I know squat about mailing systems) and postfix seems to dump about 1/2 in the relative inbox for my open exchange account and the other 1/2 sit in the queue with an MTA error, even though they are all addressed to the same person.

My main.cf was generated by a script and looks like..

Code:

command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix

myorigin = $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, ldap:ldapvdoms

Ignore the fact this is an open exchange installation the problems revolve around Fetchmail and Postfix which don't seem to be playing nice.

I think fetchmail just drops the mail to port 25, and postfix will be listening on that and pick up any mail from fetchmail, so that sounds quire right.

Keys here will be to:

1. tell us what the queue messages look like

2. what your maillog says for a "good" and a "bad" mail

Can you post those?
