A constituent pointed out that she received an emailed invoice from "[4-digit-number]@[host-domain]" rather than from our normal organization email address. (We use CiviHosting's shared server.)

I haven't made any changes to the Civi settings, and upon checking, the default From Email Address is set to "office@[our-domain]" as expected and the mailer is set to "mail()".

Other emails are sent as expected:

  • individual emails
  • bulk email
  • automatic receipts for online contributions
  • automatic registration confirmations for events

I have discovered that when a back-end user triggers "Send Invoice" for a contribution, if one of that user's email addresses is chosen as From Address to use, it is ignored and the host-server address is used. If, however, one of the CiviMail-configured From Addresses is used, it is sent properly.

I just became aware of this last week, and I have a copy of an invoice sent a few weeks before that with the correct From address, so something happened within that window of time to cause a change.

I think this might be the same type of problem as in Confirmation receipt sent from strange sender address, just maybe a different set of code.
