I've been using msmtp as an SMTP client on Win32 boxes to hand-off to Gmail
for a while with no problems.
However, odd thing today - haven't used it for a while so doing a fresh
setup on a new machine, and getting the following error message when
printing server information:
>msmtp -S
msmtp: TLS certificate verification failed: the certificate hasn't got a
known issuer
If one interrogates smtp.gmail.com (as per msmtp documentation) it seems
that Google are no longer using Thawte; the new certificate issuer is the
Google Internet Authority. [Full info at end of mail]
It all seems legit, and the underlying issuer is Equifax/Geotrust. So pick
up the new certificate from your cache, or download it here:
Equifax Secure Certificate Authority (this root is included in all browser's
root
store)<http://www.geotrust.com/resources/extended-validation-ssl/certs/Equifax%20Secure%20Certificate%20Authority.crt>
Amend the tls_trust_file directive in msmtprc.txt and way you go!
Thought this might save someone else a few headaches.
