Change Exim4 Port 25 to xxxx on VestCP

Masbroooo.......

Salah satu server kita kena blacklist google dan blacklist lainnya, otomatis ngirim email jadi ga bisa pake ip vps yang ntu.

Ujung2nya vps di suspend karna dianggap mengirimkan spam. Diaktifin lagi tapi port 25 ditutup.

Ngubek2 exim config standar sih gampang, tapi ternyata di vestacp file konfigurasi di masing masing domain.

Alih2 sambil nunggu proses whitelist dan mencegah supaya ga di jadiin spam server ane ganti dah port SMTP nya.

masuk ke direktori /etc/exim4
standar nya file config exim4 ada di /etc/exim4/exim4.conf, ternya  kalo di ls isinya beginian.

dah ane coba bikin file exim4.conf, restart service, ampe restart server tetep masih jalan di port 25.
Alhasil ane ubek2 dah tuh semua file satu2 eh akhirnya ketemu juga, ternyata ada di "exim4.conf.template"
Kalo dilihat pake nano ini isinya :

Noh ada disono, ane ganti jadi port 5xxxxx, simpan terus restart service...(sekarang ga perlu restart server). Check port yg jalan "$netstat -tulnp"

Trus ane tes lagi coba kirim email lewat console (padahal udah di blacklist, tapi karna penasaran ya ane coba aja)...... 

dan hahahahahhahahhahahah nih hasil nya...
