I'm not able to get Ubercart to send email notifications if I have the SMTP module enabled for sending email. Is this a known issue?
If I enable SMTP, Mail system and Mime Mail as I normally do for any other site, email notifications work fine for anything unrelated to Ubercart. However, when enabled, these modules (presumably SMTP in particular) seem to prevent any Ubercart notifications being sent when changing an order status and checking the option 'Send e-mail notification on update' before updating. Nothing sent, no errors logged as far as I can see.
Is this widely known in UC circles, or have I hit on a snag that could be fixed? I looked at the D7 UC issue list and see references to a similar problem. I'll be very disappointed if I can't use SMTP mail for sending UC notifications.
