i recive the mail at but the user still recive this error

do you send it from a php script ?
do you send it with SMTP ?
do you send it from rainloop ?

it depends where you send it from what could cause the error
and based on above errors it seems you need to check your postfix config , as the 3 above emails are not emails but looks like commands that get converted to emails instead

This is the email that i recive when i send a email from a gmail account or yahoo :frowning:

you need to check your postfix config file , seems there is a error in that file as the above are flags that are not suposed to be forwarded/procecced

Hi crazy92, did you manage to solve the problem?

I’m having the same issue. I know why it happened as it is related with a bad configuration of the pipe program, but I don’t know how to solve it.
