Hello,
We've had our site up for a few years now. Within the last few days, we've noticed that email was having difficulty sending from our site. Particularly when using webforms.
We are running Drupal 6.25 and I have both PHPMailer (6.x-2.2) and SMTP Authentication Support (6.x-1.1).
We are using our internal exchange server as our SMTP server. (ie. smtp.example.ca)
============================================================
When attempting to send a test message from the SMTP Authentication Support, I receive:
•Sending of at least one e-mail failed. The error returned was:
SMTP error: data not accepted.
•Unable to send e-mail. Please contact the site administrator if the problem persists.
Recent Log Entries shows me:
