Hi Xavier123,
in most cases, the
error - logs point to issues for further investigations and as well
complete depending configuration files. Please always include the new error - entries, after any changes, because they might be completely different to former ones. It wont help the investigations, if you just describe the issue, because we can only guess, what might be wrong or misconfigured.
First, I would like to point again to the "Poodle" - KB... even that there is a script provided in the KB article, you should always control the additional seetings and suggested changes in this specific article, just to be sure, that all configurations are changed as suggested - if you are unsure, please post all the mentioned configuration files, so that people willing to help can investigate the possible misconfigurations. Again... please add as well the depending error - logs, because the combination will lead to faster investigations.
In some cases you might experience issues with incompatibilities for some browser and/or eMail - clients, after you followed the KB - article 123 160. It might help to read:
... to solve such issues, because there are several additional solutions provided in this thread.
--------------------------------------------------
To start investigations, make sure, you know WHICH eMail - server combination you use ( postfix/courrier-imap - postfix/dovecot - qmail/courrier-imap - qmail/dovecot ) and always include these informations, if you have issues, because suggestions to solve your issues can vary between these very own configurations and people willing to help don't want to spend time by asking for your very own specifications on your server.
Let's assume, that you use "postfix/courrier-imap" for your server and ask yourself, WHAT are the changes that you made, when you replaced the standard Plesk - certificate? Where does postfix/courrier-imap define the paths for the certificate and where is the newly created certicate file ( *.pem ) file located?
( hint for postfix: "postfix_default.pem" - hint for courrier-imap: "imapd.pem" and "pop3d.pem" - either replace these files, of define the new path to the freshly created self-signed certificate ).
To check your complete settings, use a site like "
http://www.mxtoolbox.com" - or even better, to understand the possible misconfigurations, use a site like "
http://www.checktls.com/perl/TestReceiver.pl"
Please check as well your SPF - configuration, which is as well an issue on your server for the domain "copaindescopeaux.fr" - The standard settings "v=spf1 +a +mx -all" won't fit your needs, because of the fact, that your DNS does NOT reverses to your domain, but instead reverses to "ns370831.ip-94-23-203.eu". You can include IP and MX settings in your SPF entry and be aware that the configuration "-all" tells all other mail - servers: "if any of my configuration is incorrect, then answer with a FAIL", which will result in an abortion of the communication with the other mail - servers. My suggestion is to use an SPF - entry like: "
v=spf1 +a +mx +mail.copaindescopeaux.fr +mailcdc.fr +ip4:94.23.203.209 ?all" , because your hostname is defined as "mailcdc.fr" and the "?all" will only result in a SOFT FAIL, which never aborts a mail-server connection, even if a setting might be incorrect.
