Config Forwarding Email Exim

Cara membuat email forwarding dengan Exim Server.
Setelah selama seminggu pusing dengan cara membuat forward email, inilah hasil yang telah sukses.
Alasan saya menggunakan Exim karena untuk mengatur forward email pada exim sangatlah mudah.
karena begitu data diubah, otomatis langsung terupdate tanpa harus melakukan restart/reload.

Install Exim.
Setelah berhasil install, ubah file exim.conf
cari dan ganti dengan ini:

domainlist local_domains = @ : localhost : dsearch;/etc/exim/virtual

Kemudian pada bagian begin routers tambahkan ini:

virtual_aliases:
  driver = redirect
  allow_defer
  allow_fail
  domains = dsearch;/etc/exim/virtual
  data = ${expand:${lookup{$local_part}lsearch*@{/etc/exim/virtual/$domain}}}
  retry_use_local_part
  pipe_transport   = address_pipe
  file_transport   = address_file
  no_more

Selanjutnya buat folder /etc/exim/virtual/
Pada folder ini nantinya akan berisi file dengan nama domain
Contoh:
Forward email [email protected] ke [email protected]
Forward email [email protected] ke [email protected]
Forward email [email protected] ke pipe untuk proses autoreply
Set default email di forward ke [email protected]
maka buat file xtrsyz.org pada folder /etc/exim/virtual/
pada file tersebut tambahkan seperti berikut:

contact: [email protected]
satria: [email protected]
autoreply: "|php -q /home/user/pipe.php"
*: [email protected]

Forward email [email protected] ke [email protected]
Forward email [email protected] ke [email protected]
maka buat file mig33.us pada folder /etc/exim/virtual/
pada file tersebut tambahkan seperti berikut:

admin: [email protected]
support: [email protected]

Berikut contoh file exim.conf yang telah jadi
