Today setup a new mail server.

I have 1 mail server with 2 domain, 1 domain to internet access and 1 domain only local user.

the server is on my dmz

the problem is when the sender is from internal domain the chkuser say the following

"CHKUSER rejected sender: from <[EMAIL PROTECTED]:[EMAIL PROTECTED]:> remote <ElisaLugo:unknown:publicipaddress> rcpt <> : invalid sender MX domain"

this user not send email to other domain, only can send mail to my external and internal domain.

can disable this option for my internal domain? the option is CHKUSER_SENDERMX_STRING

How make disable this?

Help please.

Thank
