I recently upgraded to Ubuntu 20.04 from 19.10 (did a clean install). I am using the same email client (thunderbird) as before but when I try to send an email I get this pop-up.
An error occurred while sending mail. The mail server responded:
554 5.2.0 STOREDRV.Submission.Exception:OutboundSpamException`; Failed to process message due to a permanent exception with message WASCL UserAction verdict is not None. Actual verdict is HipNotify. OutboundSpamException: WASCL UserAction verdict is not None. Actual verdict is HipNotify. [Hostname=DM6PR12MB4434.namprd12.prod.outlook.com]
Please check the message and try again.
Since at this present moment I don't have time or knowledge to troubleshoot the problem with thunderbird or the knowledge I installed evolution. after setting up my email account I tried to send the same email as with thunderbird, and it came back with the same pop-up message that I got in thunderbird. I figured since it happened in two different mail clients it may have something to do with Ubuntu 20.04 itself. Any suggestion gladly accepted.
