Helo command rejected: Host not found: retry timeout exceeded

Email tidak bisa terkirim ke alamat tertentu dan saya mendapatkan error seperti ini 

agratxxx@wahanakarsa.co.id
host mail.wahanakarsa.co.id [150.107.149.228]
SMTP error from remote mail server after RCPT
TO:<agraxxxx@wahanakarsa.co.id>:
450 4.7.1 <server1.ph.gs>: Helo command rejected:
Host not found: retry timeout exceeded
hajxxxx@wahanakarsa.co.id
host mail.wahanakarsa.co.id [150.107.149.228]
SMTP error from remote mail server after RCPT
TO:<hajxxxxx@wahanakarsa.co.id>:
450 4.7.1 <server1.ph.gs>: Helo command rejected:

rikxxxxxx@wahanakarsa.co.id
host mail.wahanakarsa.co.id [150.107.149.228]
SMTP error from remote mail server after RCPT
TO:<rikxxxxx@wahanakarsa.co.id>:
450 4.7.1 <server1.ph.gs>: Helo command rejected:
Host not found: retry timeout exceeded

Kesimpulan yang diambil dari baris berikut ini <server1.ph.gs>: Helo command rejected: Host not found: retry timeout exceeded Artinya hostname tidak bisa diakses dari luar.

Cara Pengujian

Ping server1.ph.gs dari komputer anda atau dari jaringan lain. Jika tidak bisa di ping maka itulah penyebab errornya.

Solusi

Ubah setting dns dan pointing server1.ph.gs ke ip server email tsb.
