I see in my firewall telenet/25 is blocked. However smtp/25 is allowed.
Not sure how do I debug..., Any idea...

Dear All Recently I just setup postfix, dovecot, roundcube etc in a dedicated
server.
From roundcuble, I am able to send mail to my gmail account.
But from my gmail account, when sent mail to my mail id, that I setup recently, I do not see that email in roundcuble inbox. Neither that mail bounced back in gmail. Not sure, how do I debug this.
Kindly let me know how should I proceed to fix this issue.
First look in your posftix log to see if there has been an attempt to deliver it. If it hasn't gotten that far, make sure that your DNS MX record is visible to the rest of the world and also the A record for the name in the MX. Then check that there are no firewalls blocking port 25 either from the internet service provider or your router, or your host.
These are easiest if you have some outside account where you can: dig -t MX your_domain.com then dig name_of_MX_host then telnet IP_address 25 and you should get an SMTP ready prompt from your postfix.
If your domain name did not resolve in DNS at all, gmail should have rejected it immediately, but it may resolve to the wrong address or the connection may be blocked somewhere and it would retry for a while.
