I had tried it as you have shown above before but had no luck with it still sending out an email. I thought there may have been something else needed to make it work with a custom header. >From what I have read of the groupwise API docs it appears to need a header in the format: WPC-API= 1.2; Msg-Type= Task; From= Hawaii.API.Apiuser; To= Hawaii.Kona.Drew; Date-Sent= 25/1/93 11:00; Security= Proprietary;Task-Priority= 1; Task-Category= A; Begin-Time= 15/2/93 8:00; End-Time= 15/2/93 9:00; From-Text= API User; Subject= Review documentation and reply; Msg-File= TASK_10.msg; -END- The documentation specifies that the = symbol is used to seperate the field from the content. Rebol will choke however when it hits the first = sign. I had to change the = to a : before it would send anything so I assume it only picked up the standard header stuff like to, from, subject and the like and left the rest alone as they don`t fit the groupwise API without the = signs. :( Anybody got any other suggestions ?
