Finally got this installed, and want say first THANKS! Long needed feature is finally real.
Then, the weird problem. I have problems also when sending order confirmation with attached invoice.
I have now tested this in two different environments, Windows and Linux.
On Windows I have WAMP2 installed and everything works perfectly.
1. Win 32 test server using ISPs SMTP server
2. Windows XP, Apache PHP 2.2.8 and PHP 5.2.5, osCommerce 2.2-MS2
3. Windows XP Pro
4. Thunderbird 2.0.0.12 and webmail Horde
5. Html set true: no problem / Html set false: no problem
Then I have production environment on Linux
1. The standart osC mail agent: sendmail
2. Linux, Apache version 1.3.37 (Unix), 2.2.8 and PHP 4.4.3, osCommerce 2.2-MS2
3. Windows XP Pro
4. Thunderbird 2.0.0.12 and webmail Horde
5. Html set true: attachment is there, but no text
Html set false: no problems
I will keep HTML set to false to enable customers get email correctly.
Have to say, this is one very weird problem! :)
