Mark, thanks

virtual_mailbox_domains /_maps

just tested sending mail from external domain addressed to:
user+spam at vdom1.com
and, it was delivered OK to .spam Maildir, so I guess I misconfigured amavis?

I have in /etc/amavisd.conf:

$recipient_delimiter = '+';  # undef disables address extensions altogether
but, from past time, I also have, lower in the file:
$spam_quarantine_to = 'spam at sbt.net.au';  # fwd to MTA for delivery

is it this that I should remove, the "$spam_quarantine_to", does this
overrides recipient_delimiter (expect for my address at the real domain?)

thanks again for all the help
