Hello.
I made all the settings about smtp, in the file php-file on the server, in the settings in Joomla. But still i cant use smtp; owner email in property.

2011-05-31 04:42:17 (PET) processpayment 182.52.68.187 182.52.68.187.adsl.dynamic.totbb.net Error sending mail. Error caught by mailer was : SMTP Error: The following recipients failed: This email address is being protected from spambots. You need JavaScript enabled to view it.

SMTP server error: 5.7.1 : Sender address rejected: not owned by user This email address is being protected from spambots. You need JavaScript enabled to view it.

I am sure about the settings in the server that is send.one.com
I have the account and the password is in the file.
I can log in and check email, so it is my account.
port 2525 for sending.

maybe there is a relay-issue?

When I make a booking, there is three emails that the system want to send, but fails to send.

Before i tried to use PHPMAIL
Then the customer got his TWO email, but the owner did not get any.

This is not related to the wire transfer gateway. You`ll need to open a support ticket on jomres.net but first, please see this page about setting up SMTP in Jomres properly: manual.jomres.net/Configure_Jomres_to_use_SMTP

I solved it;
Had to change a few more fields in the PHP-file for phpmailer.
So now smtp working.
