Hi,
I have recently being vetting EXIM as a direct replacement for sendmail
which we use as a core mail server, serving about 40,000 users. I have a
couple of questions/problems that I was hoping someone might be able to
answer.
1. How scalable is EXIM, i.e are there any other ISP's/Organisations
using EXIM to serve upwards of 40,000 customers ? If so how does EXIM
compare to sendmail in this environment.
2. I have been attempting to get EXIM to use a binary called spop to
perform local deliveries. I have been attempting this using a pipe
transport that calls this binary and naming that transport in the
aliases director. I have pasted both these configs below.
# This is a test POP transport rule
pop_pipe:
driver = pipe
command = "/lib/mh/spop ${lookup {${local_part}} lsearch
{/etc/aliases} {$value}}"
command = "/lib/mh/spop ${local_part}
user = pop
return_output
log_output
(I have included the two command statements that I have tried above,
they were not used together !).
# This is a test POP director rule
system_aliases:
driver = aliasfile
file = /etc/aliases
search_type = lsearch
user = pop
expand = true
transport = pop_pipe
What seems to happen is one of two things, with the first command
statement exim breaks the command line into its constituent parts and
panics because it cant find a key for the lookup. With the second
command a delivery is successful but it simply uses the local_part of
the incoming address and doesn't reference the aliases expanded address
(it does do the lsearch and returns the correct alias !). I have
attached a full trace output from exim using debg level 9 for both
situations. I would be grateful if anyone comment sagely on this matter.
Regards,
Conor.
