Webservice: Sending an email without a valid recipient is not possible

Infos:

  • Used Zammad version: 6.4.0-1732617118.28f54743.jammy
  • Used Zammad installation type: package
  • Operating system: Ubuntu Server 22.0.4
  • Browser + version: Microsoft Edge 120.0.2210.133

Expected behavior:

  • Webservice forwards an email created by a contact form to Zammad and creates a ticket.

Actual behavior:

  • Since the last update to 6.4 we get the following error message: Sending an email without a valid recipient is not possible.

Was there a change in the API? What could cause such an error? We didn’t make a change in Zammad or the Webservice.

Thank you in advance!

Hi @rsc.

Yeah, there was a change in the API: Ticket creation with Send Email turns into Net::SMTPSyntaxError if customer has no email address · Issue #5308 · zammad/zammad · GitHub

When a ticket of type email should be created, it is required to specify the to parameter as well.

Thank you very much, the fix of the to parameter solved the issue.
