What we do here is that we rewrite the headers in agreement with each uucp site connected to us (we have over 100 uucp sites connected). We have then a collection of Sendmail mailer specifications, indicating rewriting and other things such as character set of the mail body. Then we use the IDA sendmail "mailertable" file to specify in site basis these mailers. So we normally do quite some things to the mail itself. We normally domainizise the uucp address - put it into proper Intenet replyable addresses when receiving mail from a Danish uucp site, and maybe convert headers into some bangified address when sending mail to the uucp site. And then we convert the body to the agreed character set, such as ASCII, Danish ASCII, ISO 8859-1, IBM CP 850 or 60 other character sets. Keld Simonsen
