My project up and beta running on google compute engine. I want to set-up email server. For that i followed http://www.krizna.com/centos/setup-mail-server-in-centos-6/
/etc/postfix/main.cf exactley how they mentioned and here is few more details
myhostname = mx.audiworld.com mydomain = audiworld.com mynetworks = <compute-instance-ip>,127.0.0.1/8
when I issue
telnet localhost 25 I am getting below error
[root@myinstance-1 ~]# telnet localhost 25 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused
namp localhost gives me
Starting Nmap 6.40 ( http://nmap.org ) at 2014-11-06 09:48 UTC Nmap scan report for localhost (127.0.0.1) Host is up (0.000011s latency). Other addresses for localhost (not scanned): 127.0.0.1 Not shown: 992 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 80/tcp open http 110/tcp open pop3 143/tcp open imap 465/tcp open smtps 993/tcp open imaps 995/tcp open pop3s Nmap done: 1 IP address (1 host up) scanned in 2.42 seconds
so the smtp port is 465 right ? then
telnet localhost 465 finally got it working
Ok this what google is telling
Google Compute Engine does not allow outbound connections on ports 25, 465, and 587 but you can still set up your instances to send mail through ports 587 and 465 using servers provided through partner services, such as SendGrid. This document discusses how to set up your instances to send email using SendGrid.
but I don't want
sendgrid to manage email . without using sendgrid how to setup Email server.?
