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
[code]...
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 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.

I tried setting smtp_tls_security_level = may = may but this did not change anything.
can i just copy/backup postfix mail queues in /var/spool/postfix and paste that folder back in after i done migrating all users and mails to a new mailserver?
View 3 Replies View RelatedI've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:

I'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :
Code:
relayhost = [myMailServer.localhost]
smtp_sasl_auth_enable = no
smtp_use_tls = no
disable_dns_lookups=yes
smtp_never_send_ehlo = yes
code....
I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.

View 4 Replies View RelatedI come back to everybody cause I don't find an explicit how to do this!In our internal network, I've created an email server with Postfix and Dovecot. (Just for internal domain, no needed to go outside)
But I've some server which use linux too. All are on CentOS 5.5.I would like to configure these servers to use my internal mail server for send email, and not configure sendmail or postfix on each server.
What I've to do exactly on each servers to use it? I search on the web but I don't find something very explicit

I have searched through piles of postfix and sendmail documentation but I'm not sure of the terminology to describe what I want to do so I'm never sure what solutions are workable. Null client, relay hosts. What I have already is a RHEL postfix server which sends and receives email. What I want to do is add a second postfix server to the network. The second server should accept only ssl smtp mail and forward it on to the main postfix server. Users shouldn't use it for normal internal sending/receiving. It's only to allow me to support ssl smtp from people working out of the office without messing about with the main postfix server. I thought a Null Client sounded likely but I don't think it will accept mail. Is it a relay host I'm trying to configure? Any pointers on configuring something to just accept secure smtp and forward?

View 2 Replies View RelatedI am looking at setting up a multiple postfix SMTP servers for a single domain. Below is my requirement, I would appreciate if someone out there could guide me to achieve this using postfix..
1. Want to setup 2 postfix SMTP Server with 1 POP3 Server.
2. Server1 will host POP3 & SMTP services for domain "metallica.one".(IP: 1.1.1.1, MX: mx1.metallica.one)
3. Server2 will host only SMTP services for domain "metallica.one" (IP: 1.1.1.2, MX: mx2.metallica.one)
4. Server1 & Server2 will be used as load balancing for sending mails. (either manual settings in email client, or auto-loadbalancing is still preferred).
5. Mail received for domain metallica.one on Server2 should be pushed/forwarded/relayed to Server1 where POP3 services are running.
6. Outgoing mails for other domains from Server2 should be sent directly to the other-domain-recipients without relaying to Server1.
I am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.

I have setup a postfix mailserver and it seems to be working ok, we are only using this to relay mail to our forum users. Its not being used to recieve any email only send them out to the internet.

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.

Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only.I had follow this how-to http://www.linuxmail.info/squirrelma...o-in-centos-5/ and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works.I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, i install VM player on it and run CentOS inside the VM Player.I want to do testing on Windows 7 side by installing Thunderbird email client program, i want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How ?
Do i have to do any other configuration on CentOS ? any DNS ? port number for IMAP,POP3 or SMTP ?
I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.
My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.
I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.
