How to / Re: How to Change your mail port (Some ISP Block 25, 26 port)

« on: April 14, 2018, 10:11:36 PM »

Hello Friends
Some ISP s is blocked 25 and 26 port ( i am from Turkiye, Blocked port 25)
solve this issue:
1-  you change your master.cf     path: /etc/postfix/master.cf

# ==========================================================================
smtp      inet  n       -       n       -       -       smtpd
#  -o content_filter=smtp-amavis:127.0.0.1:10024
#  -o receive_override_options=no_address_mappings

TO :

# ==========================================================================
smtp      inet  n       -       n       -       -       smtpd
587     inet  n       -       n       -       -       smtpd
26      inet  n       -       n       -       -       smtpd
#  -o content_filter=smtp-amavis:127.0.0.1:10024
#  -o receive_override_options=no_address_mappings

2- add this 587  and 26 ports in  your firewall incoming and outgoing ports
Your CWP panel --->> Security --> CSF Firewall
                                                 after click First Blue button Firewall Configuration
             find ports line and add your ports. if you use ipv6 add your ports there line too.

# Allow incoming TCP ports
TCP_IN = "20,21,2222,25,26,53,80,110,143,443,465,587,993,995,2030,2031,10011,30033"

# Allow outgoing TCP ports
TCP_OUT = "20,21,2222,25,26,53,80,110,113,443,2030,2031,587,993,995,10011,30033"

Note: i am not sure for add both in and out lines, but i use both

and finally you restart your services or restart your server
good luck

Will it work for Google Cloud?

Postfix / Re: Second SMTP port

« on: April 14, 2018, 09:57:47 PM »

Hello.

I want to configure postifx to use 2525 as second SMTP port.
I added in master.cf line

smtp      inet  n       -       n       -       -       smtpd
2525      inet  n       -       n       -       -       smtpd
  -o content_filter=smtp-amavis:127.0.0.1:10024
  -o receive_override_options=no_address_mappings

Problem is that every rebuild postfix configuration line
2525      inet  n       -       n       -       -       smtpd

is removed.

How can set up it permanently ?
Is ./usr/libexec/postfix/master.cf file
is used for rebuild ??

Why you want to change port?

E-Mail / Re: Can send email but not receiving email (gmail/yahoo)

« on: April 14, 2018, 02:17:20 PM »

if u cannot receive, i think mx record or hostname can be wrong in settings and records..

first check your mx about your domin mxtoolbox.com and try to fix problems first..

i installed cwp and centos 7 too and i can receive all mail but cannot send out with 25 port i dont know why..

Did you install CWP on Google Cloud?

E-Mail / Google Cloud Email sending problem

« on: April 14, 2018, 12:32:36 PM »

Hi
I setup CWP on google cloud. I can receive email but i can't send emails.
I find this article https://cloud.google.com/compute/docs/tutorials/sending-mail/. Here is mention that outgoing connections on port 25 (SMTP) are disabled, so you cannot use that for sending email programmatically.

Please suggest me best solution.
Thanks

E-Mail / Perfect Email Server

« on: April 13, 2018, 04:01:49 PM »

Hi
I just setup CWP successfully! and running my site.
Now i want to setup a perfect email server.
Right now i am with default email settings and i can only receive email but can't send. Even i can see  my sent emails in Mail Queue.
I want to setup my email in Apple mail.
It would be great if some one create a detailed post to make a perfect email server with great reception.
Where should be mention IMAP/SMTP ports with SSL and without SSL. And details about DKIM & SPF Manager.
If someone already created detailed post about perfect email server then please refer to that link.

Please suggest me best solution.
Thanks
