Server :: Unable To Send Mail Using Postfix
Jun 10, 2010
I have recently installed the ISPCP web hosting control panel. It seems that after a while running and testing I can receive but I cannot send e-mail. basically I get an error which goes
Code:
postfix/smtp[5939]: connect to alt1.gmail-smtp-in.l.google.com[72.14.213.27]:25: Connection timed out
I have, in the recent past, been able to send e-mail so I know that there is something that has gone wrong with my configuration, which I cannot. I post here my master.cf and my main.cf files as well as the mail.log file and the mail.warn....
Ubuntu Server 8.04 LTS 64x

i am trying to set up a mail server that will support users in a LAN in my school. I am using postfix on a Mandrakelinux distro.
I can send mail when I am root to the other user on my (same) machine both when in command line (mail command) and on Graphical mail client (Kmail ) but the user (sam) cannot send mail to the root account on either interfaces.
I followed the postfix configuration settings on John_Wiley_-_Redhat_Linux_Networking_and_System_Administration_3rd_Edition.

I have a server with a domain running and im trying to resolve the mail server but i can't see where to start. I use OpenSuse 11.2. Basically, for starting, i want postfix to send incoming emails to a php script or perl. for outgoing emails i guess that i could use php mail function and i will see what else to have. I configured the dns. I do a dig.mydomain.tld MX and i get the following:
mydomain.tld3600INMX0 mail.mydomain.tld
mail.mydomain.tld 3600INAmyNumericalIp
So now my system is receiving MX content but i dont know what to do.

I'm on Ubuntu 10.04 and using Postfix 2.7 with Dovecot's SASL. The issue is when sending e-mail it takes a bit of time to send. LIke for it to get connected it takes around 15.20 seconds. How can I reduce this delay so it can be sent faster?

I have spent the last 24 hours searching the internet for an issue to resolve my problem. I have tried the verious solutions posted by people and followed endless amounts of tutorials
In the end i followed [URL] line by line
This allowed me to recieve email fine, but only send email locally.
I either get a "Relay access denied" message, or as of last night is is now "Recipient Address Rejected"
Below is a link to my Main.cf file

Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:
telnet localhost 25
ehlo localhost
(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?

I'm running a server with Ubuntu 10.04 and I have installed postfix and courier. The server can recieve mail and I can fetch them using POP, but when I try to send mail it doesn't work. Postfix itself can send email if i telnet from localhost and I am using my ISP as a relay because they block port 25. I'm using outlook 2007 on my client computer and it just says that the server rejects the login attempt and tells me to check my username and password. Postfix listens on port 12 as well because the client connection also has outgoing on port 25 blocked. I have tried to use telnet to connect to the server, and I can connect. This is what I get:
[Code]....
Now what? I've tried searching for the answer but all I can come up with is AUTH PLAIN or AUTH LOGIN, but I don't know what to type after that.
