<p>Suatu ketika, salah satu server Zimbra Excellent mengalami sedikit masalah dimana port 25 yang digunakan Zimbra MTA tiba-tiba connection refused, kemudian di cek telnet port 25 email server ternyata connection refused juga. Dugaan awal saya yaitu service zimbra mta nya stopped, namun setelah di cek ternyata seluruh service zimbra running semua.</p>
<pre>zimbra@mail:~$ zmcontrol status 
Host mail.namadomain.com 
	ldap Running 
	logger Running 
	mailbox Running 
	memcached Running 
	mta Running 
	proxy Running 
	service webapp Running 
	stats Running 
	zimbra webapp Running 
	zimbraAdmin webapp Running 
	zimlet webapp Running 
	zmconfigd Running</pre>
<p>Kemudian saya coba cek log pada zimbra.log, pada log tersebut ternyata terdapat pesan error yang menyatakan bahwa service postfix not running.</p>
<pre>Jan 28 10:30:40 mail zmconfigd[1259]: All rewrite threads completed in 2.16 sec 
Jan 28 10:30:40 mail zmconfigd[1259]: All restarts completed in 0.00 sec 
Jan 28 10:30:45 mail /postfix-script[13453]: <span style="color: #ff0000;">fatal: the Postfix mail system is not running</span></pre>
<p>Saya coba cari referensi dari forum Zimbra, ternyata untuk hal itu biasanya dikarenakan ketika proses reboot server, seluruh service zimbra tidak di stop dahulu, sehingga ketika server sudah up dan service zimbra up kembali, untuk service mta nya sendiri masih menggantung dengan file pid yang masih berjalan ketika server di restart.</p>
<p>Untuk mengatasi hal tersebut kita harus hapus dahulu file master.pid tersebut. Berikut langkah-langkah nya</p>
<h4><span style="color: #0000ff;"><span style="color: #000000;">Baca Juga :</span> <a style="color: #0000ff;" href="https://rizkypratama.id/blog/2018/11/29/mengatasi-error-400-bad-request-setelah-upgrade-zimbra/" target="_blank" rel="noopener noreferrer">Mengatasi Error 400 Bad Request Setelah Upgrade Zimbra</a></span></h4>
<p><strong>Stop service Zimbra MTA</strong></p>
<pre>su - zimbra -c "zmmtactl stop"</pre>
<p><strong>Rename file master.pid menjadi master.pid_ori</strong></p>
<pre>mv /opt/zimbra/data/postfix/spool/pid/master.pid /opt/zimbra/data/postfix/spool/pid/master.pid_ori</pre>
<p><strong>Silakan di start kembali service Zimbra MTA nya</strong></p>
<pre>su - zimbra -c "zmmtactl start"</pre>
<p>Kalau tetap belum bisa, silakan restart all service zimbranya</p>
<pre>su - zimbra -c "zmcontrol restart"</pre>
<p>Silakan cek log kembali dan mestinya service Zimbra MTA sudah berjalan normal kembali</p>
<p>Mungkin cukup sekian, semoga bermanfaat</p>
