SMTP PORT 587
SMTP Secure tls
SMTP Auth true
SMTP USERNAME [email protected]

in dns setings i dont have smtpa.com host only have mail.a.com
why from scripts dont send email to users? can enebody help ?

Most likely you need SMTP HOST mail.a.com - if smtp.a.com is not configured, it cannot work
If you print error message, there may be more details available.
