i've come across what may be a bug in exim's handling of remote
lmtp. or maybe i'm doing something wrong. 8^/
i've got a redirect router that looks for a given header (a spam
indicator) and appends "+junk-mail" to the local part as such:
junkmail_delivery_router:
driver = redirect
redirect_router = normal_delivery_router
condition = [my condition]
data = ${quote:$local_part}+junk-mail
retry_use_local_part = true
this way my lmtp server knows to deliver the message into a special
junk mailbox. so this router passes on the message with a modified
local_part to normal_delivery_router:
normal_delivery_router:
driver = accept
transport = lmtp_delivery
condition = [another condition]
local_part_suffix = +junk-mail
local_part_suffix_optional = true
retry_use_local_part = true
which calls the lmtp_delivery transport to handle this message. the
transport looks like this:
lmtp_delivery:
driver = smtp
protocol = lmtp
hosts = lmtphost.my.org
hosts_avoid_tls = *
when i sent a message that's handled by junkmail_delivery_router,
it's adding the "+junk-mail" as it should, but the lmtp_delivery
transport sends the lmtp server:
RCPT TO:<dunham@???>
rather than:
RCPT TO:<dunham+junk-mail@???>
as it should. note that this doesn't happen if i use the
socket-based lmtp driver rather than the smtp-based driver. am i
doing somethin silly? or is this a bug?
the entire transport dialog follows:
lmtp_delivery transport entered
dunham+junk-mail@???
