OJS 3.1 não envia emails

Bom dia Pessoal,

Ao atualizar para o OJS 3.1 e configurando o SMTP corretamente (acredito q esteja) os emails não são enviados por nada, segue meu código abaixo, poderiam me ajudar por favor?

[email]

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

; SMTP server settings
smtp_server = mail.revistaabehache.com.br
smtp_port = 587

; Enable SMTP authentication
; Supported mechanisms: ssl, tls
smtp_auth = PLAIN
smtp_username = naoresponda@revistaabehache.com.br
smtp_password = 1,LX74bD!kZR

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

; Default envelope sender to use if none is specified elsewhere
; default_envelope_sender = naoresponda@revistaabehache.com.br

; Force the default envelope sender (if present)
; This is useful if setting up a site-wide noreply address
; The reply-to field will be set with the reply-to or from address.
; force_default_envelope_sender = Off

; Amount of time required between attempts to send non-editorial emails
; in seconds. This can be used to help prevent email relaying via OJS.
time_between_emails = 3600

; Maximum number of recipients that can be included in a single email
; (either as To:, Cc:, or Bcc: addresses) for a non-priveleged user
max_recipients = 10

; If enabled, email addresses must be validated before login is possible.
require_validation = Off

; Maximum number of days before an unvalidated account expires and is deleted
validation_timeout = 14

Conseguiu resolver? Estou com o mesmo problema.
