CiviCRM Community Forums (archive)

When sending bulk emails using CiviMail, each recipient is now being sent two copies of each message for some reason I cannot figure out. Whether I schedule the sending, send immediately and wait for cron or trigger using /civicrm/mailing/queue?reset=1, it sends out duplicate messages, but only shows delivery of a single copy.

I have my personal email on the distribution lists and keep receiving double copies, and I can tell from the tracking reports that recipients receive two, as well. Has anyone else been experiencing this lately?

I'm wondering if it may have something to do with the drupal upgrade to 6.27 and/or 6.28, since I don't recall it happening when I was on drupal 6.26.

Any helpful suggestions would be appreciated, as I don't want to annoy our subscribers by constantly sending double copies of every message to their in-boxes. Thanks!
