Hi,
We have symantec messaging gateway filtering email for 2 system. 1 is lotus notes users which is default destination routing; been the case since installation. Recently we have added an exchange system, whereby any mail received is routed to the Exchange server. I have specified all the concerned user's email address on the Protocols> SMTP> Domains. When new emails arrive, the emails are routed without any problem.
The problem I am having is that whenever an email is held in Quarantine for exchange users, when I release them I have error message 'Cannot release the message. It has either been released already or a delivery error occurred. Please check Brightmail Log for details.'
I checked Brightmail Log and having this error '[QuarantineManager] ERROR - error.quarantine.unable.release.delivery javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 550 john@xxx.com... No such user'
What can I do to solve the issue. Please help. Thanks
