I have been using OJS 3.2.1.2 for the last two years, and all things have been correct for the last ten days, all emails can not be sent from the system, and the error message
Mail failure - rejected by local scanning code
This message was classified as SPAM and may not be delivered
And when using the webmail can send from the same address of the journal to the same address in Google or Yahoo
The config is
; Use SMTP for sending mail instead of mail()
smtp = On
; SMTP server settings
smtp_server = mail.ijoir.gov.iq
smtp_port = 465

; Supported mechanisms: ssl, tls

; If any of your users have email addresses in domains not under your control
; you may need to set this to be compliant with DMARC policies published by

; Setting this will move the users address into the reply-to field and the
; from field wil be rewritten with the default_envelope_sender.
; To use this you must set force_default_enveloper_sender = On and
; default_envelope_sender must be set to a valid address in a domain you own.
