Lowest numbered MX record points to local host

Hari ini salah satu domain di server tidak dapat menerima dan mengirimkan email, kali ini masalah terjadi di server yang menggunakan Exim sebagai MTA. Domain xxxx.co.id tidak dapat mengirimkan email dengan reason seperti dibawah ini:

Requested action aborted: error in processing
451 Temporary local problem – please try later

Dan dari server sendiri ditemukan log seperti ini:

2011-01-21 11:54:40 H=smtp1.3g-net.net [202.xx.xx.xx] F=<[email protected]> temporarily rejected RCPT <[email protected]>: lowest numbered MX record points to local host
2011-01-21 12:14:39 H=smtp1.3g-net.net [202.xx.xx.xx] F=<[email protected]> temporarily rejected RCPT <[email protected]>: lowest numbered MX record points to local host
2011-01-21 12:34:39 H=smtp1.3g-net.net [202.xx.xx.xx] F=<[email protected]> temporarily rejected RCPT <[email protected]>: lowest numbered MX record points to local host
2011-01-21 12:54:39 H=smtp1.3g-net.net [202.xx.xx.xx] F=<[email protected]> temporarily rejected RCPT <[email protected]>: lowest numbered MX record points to local host

Masalah tersebut dapat disebabkan karena MX record mempunyai priority paling kecil, dan pastikan apakah domain mempunyai mx record yang tepat dan merupakan domain local. Untuk mengatasi masalah tersebut dapat dilakukan dengan menambahkan domain pada file /etc/localdomains:

$ sudo vi /etc/localdomains

xxxx.co.id

Simpan dan kemudian restart exim:

$ sudo /etc/init.d/exim restart

Done :)

Migrating Web Server From Apache To Nginx

Since two years ago (2007) this blog is hosted by Apache web server, and today I changed out the sofware in web server. I never had a “serious” problem with apache but I heard if nginx is a lightweight, high-performance HTTP server and reverse proxy. Nginx pronounced of engine-x also can handle static HTML, and does very well with dynamic (PHP) content as well. But nginx isn’t ideal for every server, nginx can’t handle SVN or WebDav, I’m still using apache for some situation :D. Continue reading “Migrating Web Server From Apache To Nginx” »
