postfix - not getting any emails. I can send out emails to outside from postfix

[ELY_M]

my server is on amazon aws service. I made sure smtpd ports are open.
I am able to use thunderbird to check my emails and send out emails.

I sent many test emails in my gmail and yahoo accounts to admin@my-domain.biz
They never show up in mailbox for user admin.
I do not see any errors in maillog

I have postfix 2.66 and dovecot installed

I see no error in maillog
so I think emails get lost somewhere.....

[White]

when you send the emails, do you get postmaster emails saying "could not send" or "retrying" to send in your gmail and yahoo accounts?

[ELY_M]

finally they came after like a day .......
took long time for the error mails to come....

[White]

is the server yours?

is it behind a router?

is the router setup to allow traffic to ports 25 and 10025 in the NAT - Virtual Server ? for the server?

[ELY_M]

it is my server. it is vps I think.
The firewall is already set up to allow smtpd's port.
I am using different port for smtpd.
I said I am able to telnet to the postfix from diff box.

[White]

i dont know, if they were getting lost then they would be being delivered somewhere and so theoretically you should have no postmaster error emails saying "The recipient server did not accept our requests to connect".

I had these errors which is why i asked the questions as it was my router which was refusing to connect the incoming emails requests to my server.

whats the result of

netstat -tap

[falko]

The problem is that you are not using port 25 for smtp. How should Gmail and others connect to your server if you use another port?

[ELY_M]

blah.... I tried falko's suggestion about port 25
I opened port 25 in firewall and open it in master.cf
restarted postfix...
now, I am getting test emails.
I sent new test email and I got new test email fast.....
