Mail in queue, cant send, 25 port blocked

Hello,

I am stuck, need help...
My mails are in queue, I guess my ISP is blocking 25 port, so how to bypass that?
Previously it worked with smtp when my mails were send trough gmail 587, but stopped working....

Been reading 3 days all sort of info, but no solution, so please someone help me out on this one!
For additional details please ask what do you need and were to look for it....

you should firstly contact your ips and then you can modify master.cf from the /etc/postifx folder to set the new port

I can send out mails from cwp roundcube to gmail and local mail.
But I cant receive the answer from anyone. Incoming mails dont come in. Thats why my ISP is blocking incoming mail from port 25.

How to bypass that? Is there an option?

I have heard that gmail could work as mail provider.

For an example, in cwp I create mails for my domains, my mail for an exapmle - mail@mydomain.lv
All mails are delivered to gmail, I only host the name of the email box but the workplace is gmail.

I dont know how to look for it, how to search, maybe someone knows?
That would be fantastic and it could work in my case maybe?

Anyone?

google:

use gmail with postfix

Your isp is blocking port 25 for security reasons, ask theen not to do that or solve it by using an external MTA

They will not unblock 25port, I need to register as a company then the port is opened, so how to bypass that.... I am using smtp, but all my incoming mails cant be delivered to my hosted mails.....

What did you mean by external MTA??? Whats that???

google it my friend!

I mean u are right that this is a support forum, but googling is way faster for simple questions ))

External mta mean that u configure Postfix to send email via other mail service
