[rt-users] exim router and transport

[Kirill Miazine]

Hi list,

I'm posting my RT router and transport that handles RT tickets. Adding
two new aliases each time a new queue is created is not neccessary with
this configuration. I use a file to help Exim decide whether the queue
exists:

hostmaster: noc
noc:        noc
support:    general
info:       general
helo:       general
contact:    general


The file does really contain a "local part -> queue" mapping. Mails to
hostmaster at example.com go to the "noc" queue and so do noc at example.com
mails. I the configuration can very easily be changed to check the RT
database to see if the queue exists.

Here're the relevant parts of the config:

<config>

# Main section

# RT
RT_QUEUES = /etc/exim/rt_queues
domainlist rt_domains = krot.org


# Router

rt_router:
    driver = accept
    domains = +rt_domains
    local_parts = lsearch;RT_QUEUES
    local_part_suffix = -comment
    local_part_suffix_optional
    transport = rt_transport


# Transport

rt_transport:
    driver = pipe
    command = /local/bin/rt-mailgate \
        --queue "${lookup {$local_part} lsearch {RT_QUEUES}}" \
        --action "${if eq {$local_part_suffix}{-comment} {comment} {correspond}}"
    return_path_add
    envelope_to_add
    delivery_date_add
#    transport_filter = /usr/bin/spamc
    temp_errors = 1 : 73: 75 : 111
    log_output
#    log_fail_output
    return_fail_output 
    message_prefix =
    message_suffix =
    user = nobody
    group = rt

</config>

My rt_transport also lets SpamAssassin to check/tag the message. If the
message gets too high spam score, my modified rt-mailgate just ignores
the message. Just uncomment transport_filter to enable spam checking.

This config is for Exim 4.
