Emails don't send in OJS3.3.0-6 - SMTP ERROR: DATA END command failed

[israel.cefrin]

Hi @jlrapter

Please, review your config.inc.php file and double check these parameters are correctly set:

• allow_envelope_sender = On
• default_envelope_sender = your_address@your_host.tld
• force_default_envelope_sender = On
• force_dmarc_compliant_from = On

Your issue seems to be pretty close from this thread/answer:

OJS 3 is not sending mail with the office365 SMTP settings

This will depend on your specific version of OJS, but in the current release (OJS 3.1.2) to always set the envelope sender on your outgoing mail, the required configuration settings in config.inc.php are all four of these: allow_envelope_sender = On default_envelope_sender = your_address@your_host.tld force_default_envelope_sender = On force_dmarc_compliant_from = On

Best,
