[courier-users] Delay before delivering mail

From: Bowie Bailey <Bowie_Bailey@BU...> - 2004-03-24 16:33

I just set up a new Courier-MTA server and came across this issue while
testing.  A message to an external email address will be delivered, but
there is a five minute delay between the server receiving the message
and delivering it to the destination mail server.  I have compared
config files between this server and my operational Courier server and
can find no differences that would cause this.  I'm including a clip
from my log file below:

Mar 24 11:05:24 bnofmail2 courierd: newmsg,id=0013BAF9.4061B1C3.00000560:
dns; bowiespc (softdnserr [::ffff:172.16.17.87])

Mar 24 11:10:49 bnofmail2 courierd: completed,id=0013BAF9.4061B1C3.00000560

What could be causing this?  This server is currently doing nothing but
delivering the occasional test message.

Thanks,
Bowie

[courier-users] Syntax error returned when e-mail address is "username" without "@domain"

Greetings to all,<br>
<br>
I have Courier 0.45.0 with POP3 and SMTP up and running on our intranet.
I am using Mozilla 1.6 and when I enter in recipient's field complete e-mail
address: <i><a class="moz-txt-link-abbreviated" href="mailto:zoran@...>, message is delivered into zoran's
maildir. But, according to specification for 'locals' file in "courier.html"
on Courier's site, same thing should happen if I enter only <i>zoran</i>
into recipient's field.<br>
Contents in locals file is:<br>
swisslion.co.yu<br>
.swisslion.co.yu<br>
<br>
Unfortunatelly, Mozilla reports 'An error occurred when sending mail. The
mail server responded: Syntax error. . Please check message recipients and
try again'. Same thing happens regardless of the machine from which I try
to send - server or working station.<br>
<br>
When I send message to <i><a class="moz-txt-link-abbreviated" href="mailto:zoran@...> it is delivered
normally.<br>
<br>
Please help, what did I do wrong?<br>
<br>
Thanx in advance,<br>
Best regards,<br>

Courier rejects all addresses that don't have a domain in them.  There are 
some mailservers which will accept an address like "zoran" and assume that 
it's a local address, but courier does not.  You MUST send mail addressed to 
"user@...". 

The check for whether an address is syntactically valid (contains a '@', and 
at least one period - '.') takes place before courier ever checks for whether 
an address is a valid user or not.  So it doesn't matter that "zoran" is a 
valid address on the server.  Courier never gets that far.

Never noticed that before (though I do now)...  That's certainly not 
true for Courier's esmtpd, even if it's true for other components such 
as sendmail or courierd.  All addresses given to esmtpd must be fully 
qualified.

[courier-users] Courier as a filtering proxy

From: Pierre Ossman <drzeus-courier@dr...> - 2004-03-24 15:36

Hi!

I'd like to use courier as a filtering proxy for an Exchange server but
I'm not quite sure how to do it.

We currently have an Exchange server handling all of our mail. Getting rid
of it completely is not an option at the moment so I have to find a
different solution.
What I'd like to do is set up a machine running courier in front of the
Exchange server. The mail is received by courier, scanned for spam and
viruses and then forwarded to the Exchange server.

I know how to set up courier to act as a proxy, that is not the problem.
What I'm having problems with is the filtering. Since the mail isn't
delivered locally I can't pipe the stuff through a filter using maildrop
or similar.
What I've been looking at is the mail filtering that is performed on the
incoming mail (filterctl & co.). I assume these will examine the mail even
in this scenario. But from what I can gather these mail filters can only
accept or deny mail. I'd like to modify it. E.g. if the mail contains a
virus I'd like it to replace the mail with a warning and the original mail
as an attachment. And for spam it would add some extra headers (using
SpamAssassin).

If I write a filter that modifies the file courier gives it to parse, will
courier then use that modified file or the original copy?

[courier-users] Authdaemon + MySQL 4.1 ?

From: Jason McCormick <jmlists@le...> - 2004-03-24 14:29

Has anyone successfully built and used Courier IMAP w/ MySQL 4.1 as an 
authentication/vhost source?  I'm trying the following and it doesn't 
seem to pick up the MySQL libraries:

$ export CPPFLAGS="-I/opt/mysql/include"
$ export LDFLAGS="-L/opt/mysql/lib"
$ ./configure --with-authmysql --with-redhat --prefix=/opt/courier
$ make

If I do that, Courier never seems to even to try to talk to MySQL.  I'm 
on RedHat 9.0.  MySQL is installed in /opt/mysql.

Thanks!

[courier-users] courier + postfix + authmysqlrc + seperating service pop and imap

From: detter werner <brotheragainstbrother@we...> - 2004-03-24 09:19

hi folks,

i got a little problem setting up courier + mysql support. well actually
this is working fine, i only want to seperate imap service and pop3
service for specific user (e.g user "a" pop3 and pop3s only, user "b" pop3
and pop3s and imap/imaps support) but i still don't get it running and i'm
not sure anymore if this is possible at all.

to give you some kind of hint - here is my authmysqlrc:

MYSQL_SERVER            localhost
MYSQL_USERNAME          user
MYSQL_PASSWORD          psw
MYSQL_SOCKET            /var/run/mysqld/mysqld.sock
MYSQL_PORT              0
MYSQL_OPT               0
MYSQL_DATABASE          mail
MYSQL_USER_TABLE        mailbox
MYSQL_CRYPT_PWFIELD     m_password
MYSQL_UID_FIELD         "103"
MYSQL_GID_FIELD         "103"
MYSQL_LOGIN_FIELD       m_username
MYSQL_HOME_FIELD        "/mail/"
MYSQL_NAME_FIELD        m_realname
MYSQL_MAILDIR_FIELD     m_maildir
MYSQL_WHERE_CLAUSE m_pop3='1' AND m_pop3s='1' OR m_imap='1' AND m_imaps='1'

the corresponding fields in the mailbox table:
m_email
m_username
m_password
m_realname
m_maildir
m_quota
m_quota_msg
m_smtp
m_pop3
m_pop3s
m_imap
m_imaps
m_stop
m_create_date
m_change_date


logging in is actually possible, but it seems like courier doesnt't care
about the MYSQL_WHERE_CLAUSE at all. i also tried to seperate the services
with other MYSQL_WHERE_CLAUSES (e.g.:MYSQL_WHERE_CLAUSE $(service)=1) but
with same result.

if i login i get the following query string in the mysql.log:
SELECT m_username, m_password, "", "103", "103", "/mail/", m_maildir, "",
m_realname, "" FROM mailbox WHERE m_username = "user" AND (m_pop3='1' AND
m_pop3s='1' OR m_imap='1' AND m_imaps='1')

i appreciate any hints, thanks for your advice,
kind regards,

werner detter

[courier-users] maximum connections in courier

From: Roger Ward <roger.ward@na...> - 2004-03-24 03:55

Is there any limitation in courier itself other than the per-process 
kernel limit and such in Linux for the maximum number of connections? Or 
would the Linux kernel not even matter?  I can't seem to sustain 200 
connections incoming and I'm trying to find out why...

Thanks again Sam.

Since I am planning to use LDAP authentication, I get the impression that
Virtual folders are implicit.

Can you tell me how I can make the 'make check' complete in this case? Since
this is a production system, I would really like to see courier complete
some kind of validation test before I install it.

Also, is this Solaris bug documented anywhere? I can probably arrange to
bring pressure to bear on my Sun rep if it is, in the hope that it will be
fixed.
