Hi everybody,

I have installed the OTRS 2.2, and then have configed send all email using SMTP relay via the graphical administration frontend.
Now I try to send an email for a ticket, I get an error message as below,

Software error:

Unknown callback: 'authname'. (user|auth|language|pass)

For help, please send mail to the webmaster ([no address given]), giving this error message and the time and date of the error.

What's happen? why?
I have tested the SMTP server via an email client, it works, so I don't know why can not send email.
BTW, I have checked the Perl Modules by use the script otrss.checkModules, reponse result information as below:
