Problem with sending mails among members...

My mail server requesting authentication.
I set the details as needed.
I've tested mail. and everything works. peope also get registration mail aswell.
I also manage to send mass email for all forum members via Admin page.

The problem is when when someone is trying to send Email to other forum member. (by clicking on send mail in his profile)
when clicking submit after writing the message they get this error:

Server Error in Forum Application
An error has occurred while sending an email.
Please contact the forum administrator.

Support Error Code:- err_mySQL_send_mail_footer
File Name:- functions_send_mail.asp

Error details:-
Persits.MailSender.4
551 Sender address is not valid for your login. Check your email program settings.


As I said. email setting are correct and works for the rest.

Thanks in advanced..

This is due to the authentication settings for the mail server you are using.

When you use the email client to send an email from yourself to another member the sending email address is set to your own to make it simpler for the recipient to reply to you via email. However, your mail server wants to have the sending address as that of a local mailbox.

We are working on a fix for this were the sending email address is set to that of the forum, and the email itself contains a message telling the recipient the email address of the sender and if they want to reply to reply on that email address.
