Cheers, will try that.


Ok tried that command and get lot of output concerning certs:

Seems to be problems with the certs with line:

Code:


verify error:num=7:certificate signature failure

No client certificate CA names sent




That said the logs show:
Code:

postfix/smtpd[23999]: TLS connection established from localhost[127.0.0.1]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)



Nit sure if related but also see this error in logs:
Code:

imapd-ssl: /etc/courier-imap/shared/index: No such file or directory


The dir /etc/courier-imap/shared/ is there but no index ?

cheers

It appears you do not have your root CA installed. Your certificate cannot be verified without the self-signed root CA available.

"A cert", or both your self-signed CA *and* server certificate?

I did section:

Code:

5.2 Adding SSL Support:

As mentioned, we want to only use SSL to connect to our IMAP server. Since we have chosen a safer method of authentication, it requires a bit more work. Let's do it now while we're still as root:
Code:

root@server # vi /etc/courier-imap/imapd.cnf

[ req_dn ]
C=CA
ST=ON
L=Toronto
O=Mail Server
OU=Automatically-generated IMAP SSL Key
CN=localhost
emailAddress=root@localhost

As you can see, I've changed the variables to match my network and location. I recommend you do the same. It doesn't really matter, but you should do it anyways. You can find all the variables to change in the "[ req_dn ]" section of the file. After you've done that, we can make our certificate file:
Code:
root@server # cd /etc/courier-imap && mkimapdcert




Looking at it now it looks only for IMAP so need to do one for TLS but not sure how?


PS many thanks for the help.

Are we trying to solve clients connecting to POSTFIX via TLS or,
are we trying to solve clients connecting to your IMAP server?

I would suggest that it is important to learn about the steps you are taking, and not blindly type them in. You are trying to configure a *secure* email system, but have no idea how, or why, or *if* it is secure.

FInally, as mentioned in the guide, make sure that fetchmail is passing the mail directly to postfix (via port 25) rather than procmal. Since i check mine via cron, I just changed my crontab to:

Code:

*/5  * * * * /usr/bin/fetchmail -K -s


(vary your options to taste, of course ... the important thing is to get rid of the '-m procmail ...' part of the line).


Hi, maybe this has been answered before, but: If I don't use procmail, how do I sort e-mails into different folders, then?

so long

Could someone take a look at this thread?
It describes the same problem as Benzman and bruor are having.

I hope someone knows how to fix this. :?

PostPosted: Mon Nov 26, 2007 4:23 pm    Post subject: Local delivery suddenly stopped working! Reply with quote

I've been going crazy for the past week! I've been using this thread's tutorial/method with great success for several years now, but last Sunday (Nov18) I upgraded postfix to v2.4.5 and ever since then I can't get local delivery to work! I tried downgrading back to v2.3.6, but no luck. I tried reinstalling everything from this tutorial, but still no luck! :x

This is the only information I get:
Code:
(temporary failure. Command output: procmail: [6503] Mon Nov 26 10:56:12 2007 procmail: Assigning "LOGFILE=/home/rpmohn/.procmail/procmail.log" procmail: Opening "/home/ross/.procmail/procmail.log")


If I could get some more Command Output, I might be able to figure this out, but I haven't been able to! Procmail is still delivering just fine through fetchmail. It's just the internal stuff. Aaaaargh! :x

Please help! -Ross

OK, If finally solved it. The problem was that Postfix didn't like the size of my bogofilter wordlist.db file. Fetchmail didn't have a problem with it, but Postfix did. Here is the relevant FAQ entry on the bogofilter website (though I never saw DB_PAGE_NOTFOUND as an error message!)

Hello would like to increase the rate at which email is processed using this setup.

How best would this be achieved?


I believe i need to increase the postfix precesses plus increase the amavisnew processes ensuring there are more amavis process than postfix processes, is this correct?

Are there any other setting that would need changing such as spamd?

many thanks

I have followed this guide to setup my mailserver and it is working fine but I see the following errors in the logs when an imap client attaches to the server:

Jan 17 11:47:51 mythtv authdaemond: PAM unable to resolve symbol: pam_sm_open_session
Jan 17 11:47:51 mythtv authdaemond: PAM unable to resolve symbol: pam_sm_close_session

Anyone an idea?

Thanks,

Nick

This guide is out date in regards to pam, guide still uses pam_stack but current pam does not use this anymore, check the pam update page as you will need to alter pam config files to new syntax

Me too, and I couldn't just let it be.

There are some references to "shared" in the file imapd /etc/courier-imap/imapd and /usr/share/doc/courier-imap-*/maildir/README.sharedfolders.txt.bz2

This last read, in part:
Quote:

NOTE:

If the "shared" directory doesn't exist, just create it.


So, on one server I did have a "shared" directory, so as root I just did "touch index" from within that directory.
On the 2nd server, I did not have a "shared" directory, so I created one, and then did "touch index"

The error messages went away and I'm happy.
