Hey sluggers,

I'm running a UOW imap setup (on a mandrake box) for a client and recently got it working with SSL, port 993 and all that. Everything was working fine with a variety of client/OS combinations until the new windows XP machine turned up today and its Outlook started complaining about invalid server certificates. I haven't looked into the problem in detail yet but just wanted a heads up to see if anyone has had this problem.


I have a similar problem with courier-(imap|pop)-ssl.  I don't think
that outlook likes self signed certs.

If you point IE to https://yourmail.server:993, you can save the cert
and in some versions that works.

Anyone else have anything?

Drop your site's self-signed Certificate Authority certificate on your website

http://www.example.edu.au/example-ca.cer

making sure you serve this with the MIME type

application/x-x509-ca-cert

Get your users to open this in IE and tell them
to accept the certificate.  The certificate should
be good (eg: not expired).

Now when your Outlook seeks your site's IMAP server's
certificate signed with your self-signed CA certificate
it will be able to validate the certificate.

If you've made the IMAP server's certificate self-signed
then you've made a mistake, as your users will need to
download a certificate for each service from your site
and add it to the CA database.  You can either fix the
error or get users to click on and accept the IMAP certificate
as well.

You should probably install your site's self-signed
Certificate Authority certificate as part of the
machie installation or Ghost image creation.

Microsoft have really good documentation on their website
discussing how it implements certificate handling.

For those not on the dark side, you'll need a recent Mozilla
version, as certificate handling for IMAP was fluffed in
earlier versions.
