Hi everybody, I configured a new instance of OJS 3.4.0.8 with the mail server running on the same server where the platform is deployed. E-mails sent from the platform are rejected by the my company’s Exchange server because the From address specified in the e-mail is empty. * * * ## **This is the error message I’m getting on my sender e-mail client:** Error Details – Error:550-5.7.1 [2a01:111:f403:da14::] Messages missing a valid address in From: 550-5.7.1 header, or having no From: header, are not accepted.

Hi Everybody, Solved my problem, for anyone having a similar issue: I reverted the config.inc.php to the original state and after talking with our IT administrator and looking specifically at the php.ini, I noticed that our server uses sendmail. Because of that, I changed the config.inc.php accordingly, see below. * * * ## **php.ini settings** sendmail\_path = “/usr/sbin/sendmail -t -i” * * * ## **config.inc.php settings** default = sendmail sendmail\_path = “/usr/sbin/sendmail -t -i” ---
