แก้ไขข้อผิดพลาด Exim: โฮสต์ทั้งหมดสำหรับ ‘domain.tld’ ล้มเหลวมาเป็นเวลานาน (และเวลาลองอีกครั้ง)

O eroare intalnita pe serverele de e-mail private, atunci cand se incearca trimiterea catre adrese de e-mail de pe un anumit domeniu sau pe o adresa de e-mail specifica.
Scenariul este cat se poate de simplu.
Avem o adresa de e-mail privata (adica nu apartine Gmail, MSN, OutLook, iCloud, Yahoo!, etc) de pe care nu putem sa trimitem mesaje catre o alta adresa de e-mail privata. Mesajul returnat va fi acesta :

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
all hosts for ‘domain.tld’ ล้มเหลวมาเป็นเวลานาน (และเวลาลองอีกครั้ง)

In cele mai multe situatii aceasta ข้อผิดพลาด apare atunci cand ฐานข้อมูล “Exim Retry” มันคือ corupta. Deci problema este pe severul de pe care se incearca expedierea mesajului-

Rezolvarea erorii consta in stergerea Exim Retry Database และ restartarea serviciului EXIM pe server.

Executati in server urmatoarele linii de comanda, pentru a sterge baza de date Exim Relay:

cd /var/spool/exim/db
rm -f retry retry.lockfile
rm -f wait-remote_smtp wait-remote_smtp.lockfile

Dupa executarea acestor comenzi prin care vor fi sterse fieserele: retry, retry.lockfile, wait-remote_smtp si wait-remote_smtp.lockfile, restartati serviciul “exim”-

service exim restart

Pentru executarea acestor comenzi trebuie sa aveti acces la consola serverului (sau acces SSH) si permisiuni suficiente.
