E-Mail / IMAP Settings Problems

« on: July 21, 2018, 04:54:36 AM »

I've setup Postfix with DKIM & SPF using host.domain.com and MX record has been set for mail.domain.com

I wasn't able to use email app to access using the domain, but it works using IP address on port 110 or 143. So I'm guessing I have some DNS issue?

Gmail is even stricter, I'm only able to get it working on port 110 but not on 143/993. I'm able to telnet to all those ports and get:

25: 220 host.domain.com ESMTP Postfix
110: +OK Dovecot ready.
143: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.

All ports have been added to firewall config. Any suggestion to get them working at 143/933 and using the domain mail.domain.com or host.domain.com?

CSF Firewall / Firewall blocks FTP passive mode

For those who cannot establish PASSIVE mode on FTP due to CSF firewall block, I recommend using this guide: https://corpocrat.com/2010/01/01/howto-enable-passive-mode-in-ftp-server-with-csf-firewall/

MySQL / Cannot run mysqltuner

I keep getting errors running mysqltuner. Even when I tried with sudo or passing on the username/password.

Code: [Select]

[root@home ~]# perl mysqltuner.pl

The only difference when I pass on credentials is and server/port:
