I recently had some issues with my research (virtual) server at uOttawa. As it was Ubuntu 12.04 decided to upgrade. Telfer "standard" is now Centos 7, and I decided to go with that. However, I'm finding that I'm getting an error when I do some email backups using fetchmail, particularly in the MDA formail step. I found that leaving out the mda line does save mail to /var/spool/nashjc OK and doesn't give the error. I've tried 777 perms for umail and umail/inbox file. I'll not pretend to know much about this sort of stuff, but did have it working OK. Here's my .fetchmailrc with pw obscured [nashjc@nash2015 ~]$ cat .fetchmailrc set postmaster "nashjc" set bouncemail set no spambounce set softbounce set properties "" set no showdots poll mailbox.uottawa.ca with proto IMAP user 'nashjc' there with password 'xxxxxx' is 'nashjc' here options keep fetchall mda "formail -c >> /home/john/umail/inbox" folder INBOX And here is what happens: [nashjc@nash2015 ~]$ fetchmail fetchmail: Server certificate verification error: unable to get local issuer certificate fetchmail: This means that the root signing certificate (issued for /C=CA/ST=Ontario/L=Ottawa/O=University of Ottawa/OU=CCS/CN=mailbox.uottawa.ca) is not in the trusted CA certificate locations, or that c_rehash needs to be run on the certificate directory. For details, please see the documentation of --sslcertpath and --sslcertfile in the manual page. fetchmail: Server certificate verification error: certificate not trusted fetchmail: Server certificate verification error: unable to verify the first certificate fetchmail: Warning: the connection is insecure, continuing anyways.
