I can't persuade fetchmail to collect mail from an Exchange server on our LAN (fetchmail and Exchange are both on the LAN).
The errors I am getting are: fetchmail: Server CommonName mismatch: myoffice.mydomain.co.uk != 192.168.11.10 fetchmail: Server certificate verification error: unable to get local issuer certificate fetchmail: Server certificate verification error: certificate not trusted fetchmail: Server certificate verification error: unable to verify the first certificate fetchmail: Error exchanging credentials
Looks like a certificate problem to me.
fetchmail: Authorisation failure on user@192.168.11.10 fetchmail: Query status=3 (AUTHFAIL)
myoffice.mydomain.co.uk resolves to the office's external IP address, although I think (from Googling) that the first line is a warning not the reason for the failure.
DNS issue - may well be link to the cert problem.
My fetchmailrc is fairly simple: set daemon 60 set invisible set no bouncemail set no syslog set logfile /var/log/fetchmail.log
poll 192.168.11.10 protocol pop3 username "user" password "password" mda
POP3 ? A bit old ? lol ...
"/usr/bin/rt-mailgate --queue general --action correspond --url http://localhost/rt/" no keep
This guy seems to have the fix: http://berqnet.blogspot.com/2009/11/exchange-2007-fetchmail.html .. but I don't know what he means by "the fingerprint of the Exchange 2007".
SSH is a BIG cert, there is a little bit, called the fingerprint, its the (maybe) CRC which say this is OK.
