I have been trying to experiment with different header types to see if that solves the problem of our anonymous server not accepting listserv mail. But I cannot find a command to put in the list to set the default header type. Is there such a command, or can it only be set for each individual subscriber? I can't find the info in the docs. Also, can anyone explain to me in simple language what the function of each header type is? -- Bruce P. A. Dienes Beware the iniquitous Disk Trolls!
