I found a HOWTO at http://lists.em.ca/?command=showmsg&list=bgware&month=200206&msgnum=17 30&thr eadid=lanfmlapjgbconfglfkb
I have installed redhat 7.3, qmail 1.03, courier-imap 1.5.3 and relay-ctrl 3.1.1
I get it work, so that my ip is put in the directory /var/spool/relay-ctrl/allow and for 15 Minutes I can send mails via smtp.
But I tried the folowing: I make in the linux-shell a telnet to the server on port 110 or port 143. Then I say "HELO", say "USER alex" and then I give a wrong password. Then courier-imap says error, but my IP is free for relaying an my IP is shown under /var/spool/relay-ctrl/allow even if i login with wring password.
I put in the files /usr/lib/courier-imap/libexec/imapd.rc /usr/lib/courier-imap/libexec/imapd-ssl.rc /usr/lib/courier-imap/libexec/pop3d.rc /usr/lib/courier-imap/libexec/pop3d-ssl.rc
before the line
/usr/lib/courier-imap/libexec/couriertcpd -address=$ADDRESS \
the line /usr/local/bin/envdir /etc/relay-ctrl/ /usr/bin/relay-ctrl-chdir \
and in the /usr/lib/courier-imap/etc/imapd /usr/lib/courier-imap/etc/pop3d
I changed the lines from AUTHMODULES="authdaemon" to AUTHMODULES="authdaemon relay-ctrl-allow"
How Do I get it work that only after successfull login the ip is free for smtp with relay-ctrl?
Does anyone have any ideas as to what he's talking about? I'm really not sure what run file he's referring to.
/usr/lib/courier-imap/libexec/imapd.rc:
/usr/bin/env - /bin/sh -c " set -a ; . /usr/lib/courier-imap/etc/imapd ; \ . /usr/lib/courier-imap/etc/imapd-ssl ; \ IMAP_STARTTLS=$IMAPDSTARTTLS ; export IMAP_STARTTLS ; \ TLS_PROTOCOL=$TLS_STARTTLS_PROTOCOL ; \
/usr/lib/courier-imap/libexec/couriertcpd -address=$ADDRESS \
-stderrlogger=/usr/lib/courier-imap/libexec/l ogger \ -stderrloggername=imapd \ -maxprocs=$MAXDAEMONS -maxperip=$MAXPERIP \ -pid=$PIDFILE $TCPDOPTS \ $PORT \ /usr/bin/envdir /etc/relay-ctrl relay-ctrl-chdir \ /usr/lib/courier-imap/sbin/imaplogin $LIBAUTHMODULES \ /usr/lib/courier-imap/bin/imapd
Maildir"
but when I put this in all the files ( imapd.rc imapd-ssl.rc pop3d.rc pop3d-ssl.rc) the IP is opened for relaying and put in /var/spool/relay-ctrl/allow if I log in via pop3 or imap with wrin password or right password. The variable $AUTHENTICAED should be read by relay-ctrl-allow bit courier-imap seems to set it even if the login fails.
I am using courier-imap 1.5.3 with relay-ctrl 3.1.1
Same for imapd-ssl.rc and the pop3d's.
Has anyone an idea why the IP is allowed even if login fails?
Greetings.
