I know a system is using ETRN and MailScanner without problems. I
checked the configuration and this is what happens:

On that system the "normal" sendmail(s) don't do ETRN. There is a host
etrn.provider (different name, different IP but same server) with a
seperate sendmail configuration which allows ETRN and which reads from a
different queue directory. I haven't yet found how messages are put in
that queue but I know it happens after MailScanner has scanned incoming
