I'm sending out an email using rules. I'm leaving the from field blank, so that it just uses the site-wide address.
For some reason it seems like Drupal is cutting characters off the from address. This is on my local dev machine so the email looks like this: firstname.lastname@example.org
When the email is supposed to get sent, I simply get a message saying "Unable to send e-mail. Contact the site administrator if the problem persists." so I checked my syslog, and all the from headers say "email@example.com" and the email can't send because my machine can't resolve that domain.
What the hell? Why has it modified the from address? I've tried changing the site email to "firstname.lastname@example.org" and when I do that nothing gets modified (IE I see email@example.com in my syslog). So why is it changing my website.meeples domain?
