Multi emails in CC how

Hello,

how can I send an invoice to multi emails?
In the early days you could use in cc: mail1@mail.com, mail2@mail.com, mai3@mail.com etc

sepperated with , a comma

But that doesn’t work anymore. Is this still possible somehow?

Thank you in advance.

Hi,

For my install (SI 1.5.11) sending to multiple CC recipients separated by e comma still works.
