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 would like some help on securing my Postfix server and to block these mischievous emails being sent from my server.
View 2 Replies View RelatedI'd like to have anything that tries to send mail locally on my machine (including crontab reports for instance) to be handled by my ISP's smtp server instead of my machine acting like it's own SMTP server. I've spent around 15 hours trying to figure out how to do this and I keep either getting into things that I don't understand, or hitting brick walls (for instance, I found nullmailer, but after installing it, it seemed like it would only work on Unix) Is there an application like nullmailer which I can use as my MTA to forward all internal mail to a different SMTP?

I'm running a server with two sites which both need to be able to send emails. Currently I have Postfix set up to send email via Google Apps. This works fine, but Google's servers ignore the From: address I specify and substitute the one I logged in with. Is there a way to make Postfix log into Google Apps with a different username based on what site the email is coming from? The server does not recieve any mail itself; Google recieves it and we have it set to forward it to the appropriate person's real email address. I'm only worried about sending mail.
(Postfix is not a requirement here, so if there's another mailer that can do this better, I'm open to ideas. However, sending email directly from the server isn't an option as it's a residential IP address and blocked by most of the big email providers.)
One of my mailservers running postfix has suddenly stopped sending mail and has been generating the following errors:
Jan 7 12:03:08 postfix/sendmail[3560]: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name
Jan 7 12:03:08 postfix/sendmail[3560]: fatal: root(0): unable to execute /usr/sbin/postdrop -r: Success
[Code].....
Things I have tried to fix this problem, but didn't work.
1) Stopped postfix, uninstalled and reinstalled.
2) Did a complete filesystem relabel with a touch /.autorelabel and reboot.
3) Did a restorecon -F -R on /etc/postfix, /var/spool/postfix and /usr/sbin/post*
Nothing above has worked and have no idea why with selinux disabled postfix works and with it on it fails.

Where is the log for postfix located?
In main.cf I changed:
myhostname
mydomain
mynetworks
home_mailbox (I want to use Maildir/)
What am I missing?
How can I stop and cancel email which are sending? Is there any command? I'm using postfix.

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 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 1 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'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.
