Zammad set an office365 channel to error because of an Email containing umlauts.
I understand that this issue ist actually not Zammad related but maybe someone has an idea what I might be missing here.
The SMTP Error is coming, if I’m not mistaken, from office365
E, [2023-05-23T09:12:29.321780 #1-112060] ERROR -- : Can't use Channel::Driver::Smtp: #<Net::SMTPSyntaxError: 501 5.1.8 UTF-8 addresses not supported > E, [2023-05-23T09:12:29.321923 #1-112060] ERROR -- : 501 5.1.8 UTF-8 addresses not supported (Net::SMTPSyntaxError) app/models/channel/driver/smtp.rb:93:in `send' app/models/channel.rb:257:in `deliver' app/jobs/ticket_article_communicate_email_job.rb:56:in `perform' lib/background_services/service/process_delayed_jobs.rb:25:in `block (2 levels) in launch' lib/background_services/service/process_delayed_jobs.rb:23:in `block in launch' lib/background_services/service/process_delayed_jobs.rb:20:in `loop' lib/background_services/service/process_delayed_jobs.rb:20:in `launch'
but from what I’m seeing, office365 should accept UTF8
what am I missing here?
- Used Zammad version:
- Used Zammad installation type: docker-compose
- Operating system: debian 11
- Browser + version: not relevant
- Email should be accepted by office365
