No, the FILEID file is the internal list.

That message occurs when you PUT the modified filelist back, not when you
issue a REFRESH  command. Most probably, you have an  entry in the FILEID
file specifying mode D1, which is invalid.

He must have done something wrong, in  any case list archives do not have
to  be manually  entered into  the FILELIST  (you can,  if you  want, but
unless you put ALL  of them there the ones not listed  will appear at the
bottom, out of sequence).

No, you  are not  supposed to  modify this  file unless  you have  a good
reason (for instance if  you want to define an access  control exit for a
file, or the like). LISTSERV assigns internal fileids automatically. Make
sure you  did not inadvertently  change the file  to RECFM V.  You should
most definitely not let the owner get or alter it.
