Server :: Postfix Not Relay Mail Via Gmail Account SMTP
Feb 11, 2011
I'm trying to set up my postfix server to relay mail (via a php cms) using Gmail's smtp on my account, but for some reason, Gmail returns an error code that StartTLS must be sent first, my postfix main.cnf file can be found at pastebin, because of this forum's text length I cannot paste my postfix main.cnf file as can be seen I have everything set and configured for Gmail, but postfix (for some unseen reason) can not send StartTLS. [URL].
My issue is that i'm trying to send emails with postfix and gmail as the mail relay,i'm trying to send emails to my self by sendmail -bv user@gmail.com
In the logs, i can understand that it been delivered to the destination, taken from: /var/log/mail.log: Apr 30 00:05:23 moni postfix/pickup[10490]: 9C7552170C: uid=0 from=<root> Apr 30 00:05:23 moni postfix/cleanup[10495]: 9C7552170C: message-id=<20110429210523.9C7552170C@moni.localdomain> Apr 30 00:05:23 moni postfix/qmgr[10491]: 9C7552170C: from=<root@moni.localdomain>, size=283, nrcpt=1 (queue active) code....
When login in my gmail account i can't see nothing under the sent / inbox / spam folder.
it's seems like the mail are been sent.. but nothing is happening.
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.
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
I'm using Ubuntu Server 10.04 and I can successfully relay mail generated by php scripts through an Exchange server.What I want to do is accept incoming mail from the Internet through postfix and relay it to the Exchange server but I want all mail that is not addressed to ...@mydomain.edu to be discarded.
I would like to setup postfix to act as a relay for the outgoing mails of a couple of servers each serving it's own domain.The mails we are talking about are standard administrative emails like user registration, password reset request. The volume of those mails will naturally grow as the site grows. Which for me poses the problem that depending on the growth of the site you will sooner or later hit the quotas imposed by (my otherwise preferred) providers like GMail or smtp.com.
So what I need is a mail relay that will only accept mails from authenticated clients from hosts in its access list and relay their mail without restrictions. Is that possible with postfix? What has to be changed in the config and what are the pitfalls?
my server is Redhat as 5 + postfix +Dovecot .when i use smtp to send mail，it can't to send,the system return "relay access denied" ? This is my maini.cf
Code: # 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
I just finish install & setup postfix & spamassasin. I can send & received email from my local area network. i already install webmail client & I can send received. When using my pda from outside my network I can received but I just can send email to my domain only. For other domain it's error relay access denied. Here my postfix configuration.
I've search high and low.. does anyone know how to configure Postfix/Dovecot to use another SMTP server (i.e. smtp.comcast.net) as my ISP blocks port 25?
My postfix is ok with receiving emails but i can send mail to my domain only [URL] When I want to send to other domains i receive this error (in the maillog):
my postfix to send and recive external emails, but many recive in trash folder.Other programer say me that is need some configurations in postfix with and dovecot to work, but i dont know what!This is my first time configuring a linux server at this week.
my main.conf sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.
After that I ran the same command with the verbose option:
/usr/sbin/sendmail -v root <prueba.txt
And this is the output:
root... Connecting to [127.0.0.1] via relay...
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600 >>> EHLO localhost.localdomain 250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES
[code]....
For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?
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:

Mutt can only read email's from my gmail account, but no emails can be send through gmail to the Internet. I need some guide for Mutt , don't know how to configure it , for sending emails via my gmail account. I tried many muttrc conf files from the Internet and even tried to configure my own muttrc file , but still no luck. My windows xp box ( Outlook Express ) is configured and works with gmail account , but I would like to explore the power of Linux.
On my opensuse 11.4 box (although I assume the version is irrelevant), I'm trying to figure out how to do something with the mail command. We have multiple smtp relay servers and sometimes I have to test to verify that mail is bouncing off of them successfully. On my laptop, in my main.cf file for postfix, I've got the relay server listed. But to test multiple servers, I have to change the main.cf, restart postfix, send message, and then repeat for each test.
I'm trying to figure out a way to specify the smtp relay on the command line. I've been playing with the -S option which is supposed to allow variables and one of the variables in the man page is 'smtp'. I've tried several different syntaxes but nothing seems to work.
The closest I've come is: mail -S smtp 10.1.0.63 -s "test" user@email.com < main.cf
That syntax doesn't give me an error but it still routes the message off the smtp server listed in main.cf which is not 10.1.0.63.
I recently created a webserver to host my website, using a Ubuntu 8.10 based system. (With some help from my experienced brother of course).I now want to create a mailserver to go along with my website. In setting up postfix to work with gmail smtp servers, I ran into a lot of permission errors.
I want to send mails via gmail with php. I need to know how to configure main.cf, php.ini, postfix,smtp... and all what is necessary. I tried a lot but no results.
I have been trying to configure the mailcheck in gkrellm to check and notify for new mail on my gmail account. I have activated pop of course...
These are the pop info taken from gmail:
Quote:
Server for incoming mail (IMAP) - needs SSL: imap.gmail.com Use SSL: Yes Port: 993 Server outgoing mail (SMTP) - needs TLS: smtp.gmail.com (use verification) Use verifiering: Yes Use STARTTLS: Yes(some clients call this SSL) Port: 465 or 587
I'm running ASSP on Ubuntu 10.04.1 it's mostly working fine. I have one problem which has been bugging me for some time. I don't want to filter outbound mail, but if I can relay (proxy) my outbound mail through ASSP, then it can automatically add to the whitelist.
As ASSP is a proxy, I need a server to send it to once ASSP receives it. I've tried my ISP, but this failed and they weren't willing to confirm if a connection attempt was received at their end.
Can anyone help me with troubleshooting steps or a better suggestion for how I can set this up. I'd love to know why my ISP setup didn't work, but I don't know a tool for monitoring IP traffic in Ubuntu SE, in windows I use Wireshark is there any equivalent I can setup for Ubuntu or a tool I can use in windows which will show all traffic, Ubuntu and windows server are on the same netgear switch, not sure it's smart enough to copy all traffic to another port for monitoring.
I'm trying to configure postfix on an ubuntu virtual machine to use gmail as a relay client. For the past two days I have been in and out of the logs, changing parameters and blindly following tutorials but I can't get anything to work properly. So far I've narrowed my problems down to tls connection establishing and a failure to authenticate, judging by the local emails I've received from "The mail system".
I am trying to configure sendmail to use GMail to send emails. I followed the instructions at[URL]lay-howto.html but it failed.After I was done with these instructions, I think I "cooked" sendmail... Can no longer configure it and it seems that I will have to start from scratch again...How to get sendmail to send emails using Gmail's SMTP server?
I have the 11.4 Gnome Distribution.everything is setup except my email sending.I have never been able to setup evolution correctly with gmail.I have followed the gmail settings of setting the smtp server to be smtp. gmail. com:465 and folowed the instructions here Evolution/FAQ - GNOME Live!to setup smtp.gmail.com with no port change.if there is no port specified the sending message window doesn't report an error it just hangs.
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd[1432]: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[166.137.139.3]: 450 4.1.8 <eppo@customconnexions.com>: Sender address rejected: Domain not found; from=<eppo@customconnexions.com> to=<xxxxxxx@aol.com> proto=ESMTP helo=<[10.25.15.47]>
I have a mail server running Postfix and the problem I'm running into is that when trying to send mail, I get a "relay access denied" error.Inside my main.cf, I did not specify 'smtpd_recipient_restrictions' so by default, the variable is:
Code: smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination The 'mynetworks' variable looks like this:
I'm trying to use different MTA servers (one for each domain) on the same public IP and port (25). Here I attach a graphic of my idea, to have a Postfix server that receives all incoming mail from internet, and relays to different local servers. esquema_mta-dns.jpg How can be configured the "Relayer MTA" ?
