Create virtual server issue

Hello

When I try to create a virtual server, I have the following error:
Failed to create virtual server : Missing file to open at postfix::/usr/libexec/webmin/web-lib-funcs.pl line 1952

But when I first create the virtual server without setting the accept mail feature, and then I had the feature everything is OK....

Thanks in advance,
