yes it is possible. Any of the following syntax will work
email1@mail.com,email2@mail.com,email3@mail.com
email1@mail.com, email2@mail.com, email3@mail.com
email1@mail.com;email2@mail.com;email3@mail.com (final version)
email1@mail.com; email2@mail.com; email3@mail.com
No matter what you do, the system will automatically convert all of the above to the "final version"
- the system deletes spaces
- the system converts comas to semicolons
the limitation of 255 characters means you can store roughly 10 email addresses of 20-25 character length (+9 semicolons separating them)
Have tried both comma and semicolon separating the addresses and it's not working. With one recipient it does work.
What else could be going on with it?
