fetchmail - problems with ssl since upgrade to 6.3.16

[Ewald Jenisch]

Hi,

Recently during portupgrades fetchmail also got upgraded to
6.3.16. Since then I'm experiencing problems when trying to fetch
mails from a pop server via ssl.

Here's the error message I'm getting:

fetchmail: Issuer Organization: <anonymized>
fetchmail: Issuer CommonName: <anomymized>
fetchmail: Server CommonName: <anomymized>
fetchmail: <anonymized> key fingerprint: <anonymized>
fetchmail: <anonymized> fingerprints match.
fetchmail: Server certificate verification error: self signed certificate
34381474120:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed:s3_clnt.c:1056:
fetchmail: SSL connection failed.

The above message normally indicates that the cert on the server might
have changed. This however is definitely not the case (I'm managing
the server myself).

Asking google I found a similar report relating to fetchmail 6.3.16
(as in my case) under Linux:

http://bugs.archlinux.org/task/19043

So my questions are:

o) Has anybody else, using fetchmail with ssl, experienced the same
problems after a recent upgrade of fetchmail under FreeBSD?

o) Any known cure against it?

Last but not least, here's my config:

FreeBSD 7.3 recent as per April 09,2010. Fetchmail 6.3.16, openssl 1.0.0

Thanks much in advance for any clue,
