can send email, but i can't receive mails..

[arginafi]

i installed dovecot-postfix, and squirrelmail and i can't receive emails...

First thing is to ask your provider whether they are blocking inbound traffic on port 25, the SMTP port. Many ISPs block that port to enforce their "no-servers" rule on residential connections. You did read your Terms of Service to determine whether you can run servers, right?

[darkod]

And very close to the first thing is: have you configured the domain to send the emails to your mailserver? Simply installing postfix is not enough, for people to send you emails the DNS has to know where to send them.

Are you using the registrars nameservers or your own?

Either way, do you have a host created pointing to your public IP?
Do you have MX record pointed to that host?

Have you purchased a domain at all?

[SeijiSensei]

Oh, and postfix and dovecot are configured by default to listen only on the 127.0.0.1 "localhost" interface. You need to change the "mynetworks" entry in Postfix's main.cf and the "listen" entry in dovecot.conf to allow them to accept traffic over the network.

[arginafi]

it's ok, my ISP has no rules for that.It worked until today, but i reinstalled ubuntu, and now i can't manage to fix it.

[arginafi]

I can send emails for example to my gmail account, i can connect from a client-side to mail-server, i configured outlook... all ok... just i can't receive any email...

[darkod]

Look above what Sensei said about the postfix listen configuration. And also at DNS. Postfix will always send emails, to receive them properly you need the DNS setup correctly.

Is it possible your public IP changed?

[arginafi]

no, my ip doesen't changed... i think DNS is configured propertly...

My local ip is 192.168.1.101 , my public ip is 86.106.196.139 , and my domain is bluetree.ro

so ... my hostname is ArgiLinux

This is my dns configuration..

Did you make sure port 25 on your router is forwarded to 192.168.1.101?

And that postfix can accept mail on 192.168.1.101 too, not only 127.0.0.1?
