Hello after two modifications on the server and on CiviCRM, it becomes impossible to send any mailing. All the email adresses are "burned" with all the email addresses being wrongly tagged as bounced. In the Report, the Bounce Type is for all emails indicated as Invalid.
Some symptoms : The table civicrm_mailing_event_bounce indicate for all mails adresses in the bounce_reason this problem :
Validation failed for: "(INVALID)" <(INVALID)>
The bounce_type_id in the is #6 which is Invalid : Email address is not valid Of course the setting in admin/options/from_email_address (From Email Address Options) have been verified, they are OK.
In the table civicrm_mailing_bounce_pattern there is 24 different patterns from the bounce_type_id #6.
There is then two clues : The server had been recently moved under PHP7.2 and CiviCRM had been enabled to handle the Multi Site Configuration with the extension CiviCRM Multisite (org.civicrm.multisite).
Did someone experimented and solved this trouble ?
Thanks for any help.
- The CMS is Drupal 7 with CiviCRM 5.4.1 on a Debian 8 server
- The bounce email boxe is located on a different Debian 8 server with Postfix Mail Server Postfix version 2.11.3
