Sentora/Postfix SMTP Email Problems

[x17andrew71x]

Good day to you all,

 

I have tried nearly everything from every different website I can find, none resolve my issue. I have the latest version of Sentora web-hosting control panel installed, I have created an email account and am able to receive mail through roundcube webmail.

I however send mail and it shows as sent successfully and drops it into the sent box, but upon checking mail logs and it shows as timed out and not sent, no matter what email I send to. Here's the latest:

Oct 21 13:30:41 login postfix/smtp[17110]: 77CB23C12D5: to= 
<x17andrew71x@gmail.com>, relay=none, delay=162982, delays=162890/0.06/93/0, 
dsn=4.4.1, status=deferred (connect to alt2.gmail-smtp- 
in.l.google.com[74.125.192.26]:25: Connection timed out)

Sometimes I will instead of get Timed out, it will show Network unreachable:

Oct 21 13:30:12 login postfix/smtp[17107]: 81AF93C16AB: to= 
<x17andrew71x@gmail.com>, relay=none, delay=73057, delays=72994/0.05/63/0, 
dsn=4.4.1, status=deferred (connect to alt2.gmail-smtp- 
in.l.google.com[2607:f8b0:400d:c00::1a]:25: Network is unreachable)

I've tried changing the sentora config on my panel to send through every different option and with or without smtp, etc. I have followed tutorial after tutorial as well on changing the port it is supposed to use. When I do this though, i try sending new mail and it still attempts to send it through port 25. no matter what i change it to, the log says :25 every time.

Please help me get this cleared up. I will be glad to provide any other information necessary. I've opened 25, 587, 2525, etc on my router and through Iptables.

I've tried: sudo ufw allow 25

I've tried: sudo iptables -I INPUT -p tcp -m tcp --sport 25 -j ACCEPT

nmap -p25 localhost shows:

Nmap scan report for localhost (127.0.0.1)

Host is up (0.00024s latency).

Other addresses for localhost (not scanned): 127.0.0.1

PORT   STATE  SERVICE

25/tcp closed smtp

 

Nmap done: 1 IP address (1 host up) scanned in 0.31 seconds

 

Why is it still blocked?
