I'm using OJS 2.4.8.1, therefore, I want to use the AWS SES SMTP Service, so, I've configured the config file config.inc.php as follow:
; Use SMTP for sending mail instead of mail()
smtp = On
; SMTP server settings
smtp_server = email-smtp.us-east-1.amazonaws.com
smtp_port = 587
; Force the default envelope sender (if present)
; force_default_envelope_sender = On
; Enable SMTP authentication
; Supported mechanisms: PLAIN, LOGIN, CRAM-MD5, and DIGEST-MD5
smtp_auth = PLAIN
smtp_username = XXXXXXXXXX
smtp_password = XXXXXXXXXX/XXXXXXXXX
; Allow envelope sender to be specified
; allow_envelope_sender = On
After sending a test I can view in error_log the following:
OJS SMTPMailer: Could not authenticate
NOTES: the username and password are correct, I tried adding the params with/without quotes, I tried with 25, 465 or 587 ports and nothing works.
Any help is well received.
