Sylpheed and Gmail "unable to get local issuer certificate" solution

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It has taken a bit of fiddling around to get Sylpheed to work with gmail
without getting errors surrounding the security certificates.  Now that I have
it working I thought it worthwhile to post this as a kind of a how-to for anyone
else who may want to do this.

Recent versions of Sylpheed say "The SSL certificate of pop.gmail.com cannot be
verified by the following reason: unable to get local issuer certificate" when
you attempt to pick up and send mail through a gmail account.  You can hit "OK"
to bypass this, but it is a nuisance to have to do that so this method will
allow Sylpheed to find the local issuer certificate that it's looking for and
stop giving the error.

You need c_rehash installed, it comes as part of the openssh-perl rpm so "yum
install openssh-perl" if you don't already have it.

There are two certificates required.  You need the Equifax certificate for
receiving and the Thawte certificate for sending.

First, make a directory under ~/.sylpheed-2.0 called certs.

STEP 1: cd ~/.sylpheed-2.0/certs

STEP 2: wget -O Equifax_Secure_Certificate_Authority.pem \
https://www.geotrust.com/resources/root_certificates/certificates/Equifax_Secure_Certificate_Authority.cer

STEP 3: Download thawte-roots.zip from http://www.thawte.com/roots, unzip it
somewhere and copy ThawtePremiumServerCA_b64.txt from that archive into the
Sylpheed certs directory.

STEP 4: mv ThawtePremiumServerCA_b64.txt  ThawtePremiumServerCA_b64.pem

STEP 5: c_rehash

That's all there is to it.  Now Sylpheed will send and receive through gmail
without error.
