OBAS Provider receives e-mail messages titled "VPS 0 has been destroyed" or "Virtuozzo Container 0 has been destroyed". Addressee name is omitted in such messages, like "Dear , ".
Such messages are by default generated by the "Container has been destroyed" Event as you can verify at
Top > Configuration Director > Event Manager > Events > Container has been destroyed > Actions > Send message
Number and addressee name are wrong because of software issue PBAS-18533 that was fixed in OBAS 4.5.5.
To resolve the issue, please upgrade to 4.5.5 as described in How to upgrade OBAS system to the latest available version.
Avoid the @@ve.id@ placeholder in messages generated by the "Container has been destroyed" event.
