[courier-users] Certificates and Outlook - Micro How-To
Good morning, as I have been trying to get IMAP-SSL to work with Outlook, I found the following to be helpful. * Make sure to enable IMAP-SSL within $SYSCONFDIR/imapd-ssl. * Make sure, $SYSCONFDIR/imapd.cnf contains the same CN information as the hostname you specified in the Outlook account. * Run $SBINDIR/mkimapcert everytime you change imapd.cnf. Delete the $SHAREDIR/imapd.pem file before running $SBINDIR/mkimapdcert * Create you .P12 certificate using the following command line (thanks to Jeroen Massar) openssl pkcs12 -export -in imapd.pem -out imapd.p12 You will be asked for a password. Remember this, as you will need it during the import process in the next step. * Double-click on the resulting imapd.p12 file and import it into your Windows system. * Restart courier. (I guess you only need to restart imapd-ssl ?!) * Within Microsoft Outlook, change your account to require secure communication. * Restart Microsoft Outlook. The above worked for me. If you find an error, tell me. Thanks. HTH rgds pos ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

Re: [courier-users] Outlook and Outlook Express support
Paul, the only problem i've run into is in regards to a popup window when using SSL. I used OpenSSL rather than verisign et al. for the certificates on the mail server. A little finagallig got all the other clients to be ok with a self-signed certificate, but Some (not all) userers with the latest version of OE can't seem to get one of the are you sure security popups to go away when using SSL to connect. A post earlier today might have the solution though. Thats all I can think of off the top of my head. Most my users use pine. David.

[courier-users] Virtual Users w/ Virtual Domains w/ LDAP
I'm using courier 37.2 with ldap very, very happily. I am going to start using virtual users w/ virtual domains and I thought that it might be possible to configure them without using the full email address as the uid by just substituting the ldap virtualHost varable as the LDAP_DOMAIN in the Authldaprc. In my testing I found that the same uid [yolac] different domains [guey.net|localfolks.Net], esmtp had no problem delivering the email to either /home/virtual/[guey.net|localfolks.net]/yolac but imap substituted the value of LDAP_DOMAIN after the user so it was always the value of LDAP_DOMAIN. By watching the search in slapd.log I decided to change the value of LDAP_DOMAIN manually, reset and I received the email as expected. Does this or maybe another varible LDAP_DYNAMIC_DOMAIN make any sense? The authldaprc file users other ldap values already.

ESPTM (RFC 1869) is filtered because it may allow some fairly powerful commands to be executed on your mail server that are unecessary for typical internet email exhanges. Someone else may be able to elaborate on the risk of allowing ESMTP, but one example is the VRFY command which will tell the client whether a user account actually exists on the server and sometimes replies with the user's full name.
