Phpmailer vs drupal_mail

I do not have Mime Mail installed / downloaded so not using it.
I do have Phpmailer configured properly and test email is going to the debug_email address instead the one I typed in in the test, so it does work.
Making an order as anonymous or registered user in website's store that Ubercart provides, all emails sent by Rules for successful shopping goes to respective addresses instead to the debug_email address.
Mail headers clearly show that email wasn't sent by Phomailer, unlike test email that confirms it. At first I thought the problem might be tokens but its not. If I write down mail address instead token, it still sends to that address instead debug_mail address.

From modules, I use:
Phpmailer, Ubercart, Admin menu, Apachesolr, Imce, a couple of Media and CCk modules, Views, i18n... So nothing really special.

Checking the code in Ubercart, to be precise in it submodule "order", I see they use drupal_mail hook to send those emails. Code looks fine so the only thing that stinks in the whole story atm is Phpmailer.

Any ideas? If more info needed, I ll provide. Thanks.

I put today debugger on and confirmed that when sending for example invoice mail or order mail from Ubercart, it never enters or uses Phpmailer class. It simply goes to mail.inc in core and finishes stuff there through drupal_mail and upon success returns back in ubercart to write message that its sent.

Then I examined sending test mail from Phpmailer and it used Phpmailer class and processed all ok. Also watched debugging results when admin makes new user's account and uses "send notification to user". That email also uses Phpmailer.

So there seems to be an issue Phpmailer versus Ubercart?
Note that I used Ubercart - Phpmailer combo on D6 and it worked.

This is an example of execution round for sending invoices via admin panel in order page:

• admin enters on which mail to send invoice
• it stops in uc_order.admin.inc function uc_order_mail_invocie_form
• then it jumps to uc_order.module line 568 which is function uc_order_mail in case "invoice"
• from there it goes to mail.inc on line 165 which is drupal_alter
• then it goes to uc_order_invoice_form_submit line 1328 in uc_order.admin.inc and checks if mail was sent. If yes, set drupal message

So nowhere gets in touch with Phpmailer at all! I believe for reproducing this D7, Ubercart and Phpamiler would be enough. Just make a product, let anon or user buys it and check if rules are set to send mail to user for order on email.

Ok I solved issue by adding module MailSystem. Then added module Mime Mail to handle HTML UC mails and now all works. For what I had on D6 where 1 module was used (Phpmailer), on D7 I need to use 3.

Thanks for the help oadaeh.
