I have changed the over sized router to the folloing to allow fro a
separate filter
Code:
--------------------
blackberry_notify:
driver = redirect
allow_fail
allow_defer
condition = ${if >{$message_size}{1M}{0}{1}}
data = ${lookup{$local_part}lsearch{/etc/blackberry.aliases}}
headers_add = X-BlackBerry-oversize: Message was too large to deliver to BlackBerry\n
user = exim
unseen
no_verify
redirect_router = blackberry_oversize
--------------------
and I have added the following redirect router below the local user
router
Code:
--------------------
blackberry_oversize:
driver = redirect
unseen
no_verify
user=exim
allow_filter
file = /etc/mail/exim-blackberry.filter
--------------------
The exim-blackberry.filter looks line this
Code:
--------------------
# Exim filter
if "${if def:header_X-BlackBerry-oversize: {there}}" is there
then
mail to $header_to
from $header_from
reply_to $header_reply-to
subject $header_subject
text "\
The message sent by $h_from was too large to deliver to your\n\
blackberry ( size = $message_size )\n\
"
endif
seen finish
--------------------
Now the issue seems to be when the process comes back from this filter
the debug output says transport: <none>
Below is the last output of the exim run as it considers the resolved
addess aquired by the alias look up in the "oversized" router the
domain is a remote mail server but I have XXXX ed out the domain. mail
can be sent to this address directly so it is not a "general" routing
issue.
Code:
--------------------

>>>>>>>>>>>>>>>> Exim pid=8191 terminating with rc=0 >>>>>>>>>>>>>>>>
--------------------
Is it possible that the mail command in a filter file does not inject
the message back into exim and that it simply returns the message back
to where it came into the filter?
Thanks,
Kevin
