Hi all,
I would like to set the outgoing interface to the IP address assigned to the user's domian.
The problem I am encountering is that not all domains have thier MX set to an IP on our server (because some domains are using a mail filtering server that relays the message to our server after filtering).
Is there a way to rewrite the transport's 'interface' lines below, so it will attempt to use the MX, then the A record, then a default IP (the servers main IP) in that order?
remote_smtp_owm:
driver = smtp
helo_data = $sender_address_domain
# interface = ${lookup dnsdb{a=${lookup dnsdb{mxh=$sender_address_domain}}}}
return_path_add = true
remote_smtp_local:
driver = smtp
# interface = ${lookup dnsdb{a=${lookup dnsdb{mxh=$sender_address_domain}}}}
helo_data = $sender_address_domain
return_path_add = true
remote_smtp_alias:
driver = smtp
helo_data = $parent_domain
# interface = ${lookup dnsdb{a=${lookup dnsdb{mxh=$parent_domain}}}}
return_path_add = true
remote_smtp_bounce:
driver = smtp
helo_data = ${lookup dnsdb{defer_never,ptr=$interface_address}{$value}{$primary_hostname}}
# interface = $interface_address
return_path_add = true

There's no port of libdkim in the ports system for OpenBSD4.5.
A recent ports snapshot doesn't include it, so it looks like it
won't be in OpenBSD4.6. Obviously there'll be no libdkim-flavoured
version of exim in OpenBSD4.5/6.
The above's not a problem. libdkim-1.0.17 won't compile out of the
box on OpenBSD4.5. It fails with the error:
dkimverify.cpp: In member function `int SelectorInfo::Parse(char*)':
dkimverify.cpp:1199: error: invalid conversion from `const unsigned char**' to
`unsigned char**'
gmake: *** [dkimverify.o] Error 1
(The above is with gcc (GCC) 3.3.5 (propolice), later versions of
gcc may be more lenient.)
The fix is simple:
--- dkimverify.cpp.orig Wed Apr 2 12:42:08 2008
+++ dkimverify.cpp Tue Oct 6 09:49:47 2009

{
unsigned char *PublicKeyData (unsigned char *)values[4];
- EVP_PKEY *pkey 2i_PUBKEY(NULL, ((const unsigned char **)(&PublicKeyData)), PublicKeyLen);
+ EVP_PKEY *pkey 2i_PUBKEY(NULL, ((unsigned char **)(&PublicKeyData)), PublicKeyLen);
if (pkey ðNULL)
return DKIM_SELECTOR_PUBLIC_KEY_INVALID;
so it should be straightforward to build a libdkim-flavoured version
of exim from source.
