The error seems to indicate that the specific server configuration is incompatible with the sendmail function.

Policy restriction in effect. The fifth parameter is disabled on this system

I suspect you may need to contact your host about that to check whether they can change it.

 

[Mike]

You can disable the "-f" parameter option to get around that, but disabling the parameter like that may lead to lower deliverability.

 

[Tealk]

the support doesn't know what he should do

 

[Paul B]

As Mike said, uncheck this.

 

[Tealk]

what does this option?

 

[OldCoals]

I am getting the same issues randomly, with the -f option enabled.
