SendMail() - how to determine #pb_mail_error reason?

[jassing]

I'm sending an email, but mailprogress() returns -2;
I tried adding #pb_mail_Debug, but nothing additional was displayed.
the mail is sent...

#PB_Mail_Debug : to print in the console debug information.

Have you open a console?

yes.
