Ubuntu Servers :: Can't Send Mail Using PostFix - Only Receive Mail
Jun 30, 2011
I set up my mail server using the guide here: [URL] I am able to receive mail, I can send mail locally, but I can't send to external addresses. This is in my mail.log: Quote: Jun 30 14:40:43 Server postfix/smtp[10725]: 2FD9322015BF: to=<myemail@gmail.com>, relay=none, delay=1634, delays=1484/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.65.27]:25: Connection timed out)
This is my main.cf:

nstalled Postfix + Dovecot + Roundcube on a plain CentOS 5.5 box, let say on "site.com".I cant send or receive emails. When I try to telnet from both localhost and from the outside world, it can not reach the mail server.Testing itself on port 25:
Code:
[root@srv-estudio:~]telnet mail.site.com 25

I do not know why I could send email outside but not receive. I use relay to my ISP that port 25 is blocked by my ISP. What can I doing with configuration when it should be works to receive mail? Okay, I have sent a test e-mail between localhost and it works. I can send from mailserver to my gmail without problem. So why I cannot receive email from gmail?

i basically had this system installed for our mail system.The setup is as follows:
1. Operating system installed is Debian ver. 5.0.3
2. Roundcube is installed as a webmail(if its right for me to say that)
3. The server is hosted right here at our offices
4.The server uses relay system to send mail i.e. relays all our mails to our ISP
That all i can say about the configurations becuase thats as much as i understand it.The problem now is that we are not able to send or recieve emails from both internal and external.I tried to send mail to a collegue in the office who is on our local LAN,Roundcube says sent successfully but the person does not recieve the mail.i tried to send to my yahoo address but nothing.I dont know where these mails have been trapped.

I have configured fetchmail, sendmail/postfix and mutt to act as a relay to receive mail. I can receive mail fine but I cannot send mail. Its working fine on my one box but on the one acting as a nat I am having issues. This is my mail log from the nat box.

Alright guys, I've looked over every thread regarding this issue on this forum, and many others; yet I cannot find out why my mail is being bounced without error from my external gmail account.From what I've seen, you guys need to start off by seeing my postconf -n
Code:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.

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.

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.

The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

I was running Ubuntu 9.04, no problems. I did a new installation of 10.04 and could not send or receive mail (Thunderbird). Both would time out. tried two other mail programs to see if Thunderbird was the problem, but they did the same.So I did dual boot installation, with 9.04 and 10.04. The same: mail OK in 9.04 but not in 0.04. So that seemed to eliminate everything as a problem outside of my computer.One night I remembered that ipv6 could be a cause, and toggled it in Thunderbird. It has been an "almost". I can now receive but not send.For example, the bottom bar will say: "Connecting to smtp.edicionescc.com" and after a while time out.I can ping smtp.edicionescc.com with no problem

so I'm really new to using Linux, and I searched the forums, but most people seem to have trouble sending mail, not receiving it. When I send mail from the CLI, it gets delivered fine (from travis@travishoward.net) But when I try to reply or mail to the server, I get this message back:
Code:

I've set up both Postfix and Dovecot on my server. I can currently send mail via Outlook to Postfix over Port 587 (rather than Port 25), and receive mail from Dovecot on Outlook. However, the only mails I am able to receive are those originated from within the server itself. If I attempt to send an e-mail to the address my Outlook listens to, the mail will never reach my Outlook. In other words, no one on the Internet is able to send mail to me.
Can someone tell me:
1) If setting Postfix to listen over Port 587 for my Outlook to send mail outwards is preventing me to have Postfix to listen to mails coming from the Internet? Would I have to turn on both Ports 25 and 587 in /etc/postfix/master.cf?
2) I have configured my Postfix to use saslauthd by authenticating those who are on /etc/passwd. This means I can enter my Linux account details into Outlook in order to connect and download messages. However, does this mean other MTA servers on the Internet who doesn't know my account details are unable to authenticate with my Postfix server and send mails to it?

I recently purchased a domain and I have setup what I believe are correct dns records from the domain companies control panel. I have the domain pointing to my server and that's working fine. I also have an MX record for my domain. Now, I can send emails from my email account just fine however I cannot receive any emails coming in to my account. Heres an example:
[dalton@int-interactive mail]$ echo "hello world" | sendmail -v dalton@int-interactive.com
dalton@int-interactive.com... Connecting to [127.0.0.1] via relay...
220 int-interactive.com ESMTP Sendmail 8.13.8/8.13.8; Sun, 21 Aug 2011 14:45:16 -0400

In my continuing quest to live without X most of the time, I am trying to set up fetchmail and Mutt to get and send mail. I only want to be able to send and receive text based mail, and so far I am running into trouble with what I think should be pretty simple. For receiving my mail, I believe I only need to create a .fetchmailrc file in my home directory with the entry:
Code: poll [URL] protocol pop3 username "myusername" password "mypassword" But I get:
2 messages for myusername at mail.myISP.com (7965 octets).
fetchmail: connection to localhost:smtp [127.0.0.1/25] failed: Connection refused.
fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching from wetumpka@mail.btopenworld.com and delivering to SMTP host localhost
reading message myusername@pop-smtp.ISP.mail.fy5.b.yahoo.com:1 of 2 (2734 octets)fetchmail: Query status=10 (SMTP)
It appears to me that it is finding mail but does not know where to deliver it and is refused a connection to my machine. Also, I cannot figure out how to set up my SMTP for my ISP in Mutt to send mail. Can someone point me to a simple tutuorial on how to do these things. I really only want to do what you would with Thunderbird, but from the command line.

recently i configure postfix on my fedora core 9 system i want to send mail from one user to another till now i did not create any user, i just configure the main,cf file with the help of some link i found on internet
here is my main.cf file
# Global Postfix configuration file. This file lists only a subset
# of all parameters. For the syntax, and for a complete parameter
# list, see the postconf(5) manual page (command: "man 5 postconf").

# For common configuration examples, see BASIC_CONFIGURATION_README
