It does not allow to send the mail without "CC", "CCO"

Hello!
When trying to send an email, you must always fill in all the fields with the destination email ...
For what is this?
Thank you!

Hi,

I don't observe this issue.

[dabasystem]

I can not send an email only with the sender. I have to put value in the "CC" and "CCo" fields

[yuri]

Maybe it's caused by some customization you might have?

[dabasystem]

I see that the error is widespread ... that is, for example does not recover who sends me the emails. There is some way to reset everything, I have not made any customization, but just in case.

Thank you!

SOLVED! I have entered the MySql and I have truncated all tables referring to the email. It worked, I investigated a bit and in the end it was because there was an email account with all the "null" data.
This caused the error.

In case someone is in my situation!

Do you know how null appeared there? It would be good to preclude such a situation.

I have no idea, but we made a server migration .. the only explanation is that when importing the database will generate this "null". The problem is that this "null" affected everything that had to do with the treatment of the email.
