Postfix / SMTPD - TLS Library Problems

onlinewebs · May 26, 2014

Hi,
I am using Debian Wheezy on ISPConfig3.
I have tried to reset certificates using several online sources; however, I am consistently seeing the following errors in my Mail warn-Log:-

Any help would be appreciated.

Seems as if you followed the guide to install startssl certs but the bundle cert file /usr/local/ispconfig/interface/ssl/startssl.chain.class1.server.crt is mising.

Thanks till for the note.
Any advice of how to restore to the original setting?
Would reinstalling postfix and then generating the certificates work?
