RT- unable to fetch emails from our office 365 account

Hi,

I am new to Request tracker installation and have followed the installation instructions from the following links:

  1.  http://binarynature.blogspot.co.uk/2013/10/install-request-tracker-4-on-ubuntu-server.html
    
  2.  https://help.ubuntu.com/community/Request%20Tracker
    

but I am unable to fetch any emails from our office 365 account and the fetchmail.log is showing the following error message (snapshot attached)
500 Can’t connect to request.domain.com:443 (certificate verify failed)

It seems like rt-mailgate cannot verify the ssl certificate. I have also attached the snapshot of the fetchmailrc file.

I have read this article, http://lists.bestpractical.com/pipermail/rt-users/2012-January/074546.html but would request to give more detailed resolution for the issue. Much appreciated.

Regards
Rohit

It seems like rt-mailgate cannot verify the ssl certificate. I have also
attached the snapshot of the fetchmailrc file.

So it sounds like fetchmail is working fine but rt-mailgate can’t
connect to your RT. You can use --no-verify-ssl in the rt-mailgate
command but that isn’t recommended, you should get the certificate or
system configured so that your system trusts it.
