The relevant section of my /etc/fetchmailrc reads as follows:

  poll "pop.googlemail.com" with protocol pop3 port 995
        user "sebyte" pass "xxxxxxx" is "sebyte" here
        options ssl sslcertck sslcertpath "/home/sebyte/.gnus.d/certs"

Appears ok.

I am getting the following log output:

Hm. Does another "-v" provide detail?

Does fetchmail 6.3.0 or 6.3.1-pre1 work for you?  See

http://fetchmail.berlios.de/              for 6.3.0

http://home.pages.de/~mandree/fetchmail/  for 6.3.1-pre1

I haven't got my password wrong so presumably the problem lies with the
certificates I've generated.  Is there a way to check these?  The instructions
in the `Postfix tutorial' above suggest using the following command:

  $ openssl s_client -connect pop.googlemail.com:995 -CApath \
            /home/sebyte/.gnus.d/certs

but in my experience, it says:

  "... verify return code: 0 (ok)"

whether I specify `/home/sebyte/.gnus.d/certs' as the CApath, or `rhubarb'!

Interesting, I get (with OpenSSL 0.9.7g 11 Apr 2005):

CONNECTED(00000003)
depth=0 /C=US/ST=California/L=Mountain View/O=Google Inc/CN=pop.googlemail.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 /C=US/ST=California/L=Mountain View/O=Google Inc/CN=pop.googlemail.com
verify error:num=27:certificate not trusted
verify return:1
depth=0 /C=US/ST=California/L=Mountain View/O=Google Inc/CN=pop.googlemail.com
verify error:num=21:unable to verify the first certificate
verify return:1
...

Is another copy of the google root certificate in /etc/ssl/certs (or
whatever else the SSL default path for certificates is on your system)?
AFAIR -CApath just adds to the path without removing the former path
components.
