using smtpmail.p, problems With attachment

Could anyone think of what Could be wrong?

Having used smtpmail.p without any problems, and after the admin guys have done some With the environment we now can't get the attachment to work... As far as we know, there has been no changes to the code.

I testet the following:

DEF VAR ocReturn AS CHAR NO-UNDO.
DEF VAR obOk AS LOG NO-UNDO.
DEF VAR cFil AS CHAR NO-UNDO.

cFil = "x:\myfile.txt".

       RUN mail/smtpmail.p (
           INPUT "myPop3server",                                        /* Pop server */
           INPUT  "myepost@post.no" ,                                            /* Sendes til */
           INPUT "myepost@post.no",                                        /* From */
           INPUT "",                                             /* kopi til ; */
           INPUT "myfile.txt:filetype=binary",                                /* Vedlegg fil/type */
           INPUT cFil,                                    /* Vedlegg fil adresse */
           INPUT "Testemne",                                          /* Subject */
           INPUT "Testbody",                                          /* Body */
           INPUT "",                                             /* Mime header */
           INPUT "text",                                         /* Body type */
           OUTPUT obOk,
           OUTPUT ocReturn).
    END.

    MESSAGE ocReturn
       VIEW-AS ALERT-BOX INFO BUTTONS OK.

The mail is received, but no attachement. I am not able to do that much testing on this Production environment, so I Wonder if anyone could point me in a direction to investigate...
