There was a problem sending an email , please contact your system administrator or try again latter

My clients can submit papers accuratley but they only receive the error
“There was a problem sending an email , please contact your system administrator or try again latter” even though there is no problem with submitting the paper…

Hi @noor2k9,

Double-check OJS’s email delivery configuration (particularly the smtp options in config.inc.php). This message means that OJS tried to deliver an email, but it was rejected.

Dear asmecher
Thanks for your reply i have checked my configurations in config.inc.php , it is as follows

;;;;;;;;;;;;;;;;;;
; Email Settings ;
;;;;;;;;;;;;;;;;;;

[email]

; Use SMTP for sending mail instead of mail()
smtp = on

; SMTP server settings
smtp_server = smtp.gmail.com
smtp_port = 465

; Enable SMTP authentication
; Supported mechanisms: ssl, tls
smtp_auth = tls
smtp_username = myid@gmail.com
smtp_password = mypassword

; Enable suppressing verification of SMTP certificate in PHPMailer
; Note: this is not recommended per PHPMailer documentation
; smtp_suppress_cert_check = On

; Allow envelope sender to be specified
; (may not be possible with some server configurations)
; allow_envelope_sender = Off

Hi @noor2k9,

To use Google’s SMTP service, you need to enable “less secure applications” in your Google configuration – see https://myaccount.google.com/lesssecureapps.
