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].

OpenSUSE :: Postfix Relay Denied On 11.4

Jun 4, 2011

I was never confident with postfix, but used it for several years now on my own server. I even noted the exact config used. But my old server crashed and I have to build fast a news one and I don't receive mails anymore. Here is the log message when trying to send to me from gmail:

Jun 4 08:06:34 ks3095514 postfix/smtpd[4008]: connect from mail-pw0-f50.google.com[209.85.160.50]
Jun 4 08:06:34 ks3095514 postfix/smtpd[4008]: NOQUEUE: reject: RCPT from mail-pw0-f50.google.com[209.85.160.50]: 554 5.7.1 <jdd@dodin.net>: Relay access denied; from=<lesrevesdeness@gmail.com> to=<jdd@dodin.net> proto=ESMTP helo=<mail-pw0-f50.google.com>
Jun 4 08:06:35 ks3095514 postfix/smtpd[4008]: disconnect from mail-pw0-f50.google.com[209.85.160.50]

The main.cf file is the openSUSE default one (see below). Part of my problems seems to come from the reverse. I *could once* receive one test messsage to " ks3095514.kimsufi.com" (the default reverse/domain name) (below, commented out), but not for my own domain (dodin.org). Most of the time the only necessary lines are mydomain, myhostname, myorigin and mydestination, but this don't work anymore. New defaults??. local (from and to the server) mail works, root can send to jdd and I read it from home.

mydomain = dodin.org
inet_protocols = all
biff = no
mail_spool_directory = /var/mail
canonical_maps = hash:/etc/postfix/canonical
virtual_alias_domains = hash:/etc/postfix/virtual
relocated_maps = hash:/etc/postfix/relocated

CentOS 5 :: Postfix Mail Server Will Not Start Tried To Change Postfix Smtp Port?

Oct 4, 2010

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

Fedora Servers :: Set Up An External SMTP Relay Box?

Jun 29, 2011

I've tried googling this, and am having trouble finding something that doesn't end up being dizzying or confusing.

I was wondering if anybody could provide me with a concise, conclusive answer/guide.

I have a set of servers which require redundant SMTP relay. The first two of their SMTP relays are their own SMTP servers, and as such, are not dependable in the event that their network/servers go down. Their monitoring software runs on their machines as well, and uses the SMTP servers they themselves host.

I need to set up an external SMTP relay box that they can use to relay their monitoring alerts/admin notices in the case that their mailservers go down.

I have a company exchange server with pop/imap support @ my disposal but, unfortunately, that box runs Windows and does not permit any changes to services or additional software to add for the purposes of relaying clients.

So now, I need to create a dedicated linux box that can act as a relay to send email coming from the monitoring/admin/alert software in case their first two smtp servers have gone down.

Security :: Secure Webmail - SMTP Relay In DMZ?

Apr 11, 2010

When you set up a webmail solution these days, either on your home LAN or at a small business. What steps do you take to make the solution as secure as possible? A couple of years ago it was sufficient to port forward both port 25 and 80/443 to you server located on the internal LAN. Today you're more likely to have a SMTP relay in a DMZ of some kind. But the webmail, how do you solve this? Do you place a dedicated webmail frontend in the DMZ and open ports towards the internal LAN, or do you just place the entire server in the DMZ? I'm looking for input for a small network/home LAN so it shouldn't be to complex.

Software :: How To Setup Sendmail As SMTP Relay?

May 15, 2011

I want to setup sendmail using my username and password on my ISP to be able to send out messages.This is actually true as the mylocaldomain is not a public Internet domain. Just a localdomain for our local network. However, I was expecting that to change to the username in my authinfo "myusername@myispdomain" since this account is authorized to send out email with my ISP.

Ubuntu Servers :: Setting Up Authenticated SMTP Relay?

Jun 15, 2010

I am new to the Ubuntu Community and just starting to build my Ubuntu 10.04 Server. I am a novice in Ubuntu, though maybe not a full n00b any more

I travel around a lot with my laptop, (also Ubuntu 10.04). However, my ISP does not allow me to send email via their SMTP when I am not in their IP range.

Since I have this little server I am building, I thought it would be nice if I could have my own SMTP relay. The objectives would be simple:

- I do not need a mailbox or POP server (yet).
- I wish to send email from any place in the world. I can not use a filter on IP ranges or local networks only.
- If my server could do this, I just configure Evolution on my laptop to send mail to my home IP address, using some sort of authentication and/or security/encryption (whichever is easy to implement).
- My server then just forwards my mail to my ISP. Since the server is inside the IP range, it can be handled as usual.

I have been digging through several howto's and the ubuntu server guide, searching some forums etc. Even while I don't fully grasp the things explained, I can't get the idea that one of those is "Just what I need".

Even still, if there is some other service outside my own that can do this (a public SMTP relay maybe?) I would also be happy to consider as long as it is safe and does not "eavesdrop" on my messages.

OpenSUSE Network :: Specifying Smtp Relay On Commandline Of Mail Command?

Aug 9, 2011

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.

Ubuntu Servers :: Mail SMTP Relay / Copy All Traffic To Another Port For Monitoring?

Sep 2, 2010

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.

Current setup

Inbound

mx -> router -> ASSP -> Exchange 2003

Outbound

Exchange 2003 -> mx

I'd like to setup outbound as either

Exchange 2003 -> ASSP -> <ISP> SMTP relay
Exchange 2003 -> ASSP -> <relay running on Ubuntu eg postfix>

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.

Ubuntu Servers :: Noob Setup Simple SMTP Relay Contradiction In Terms?

Jun 7, 2011

Is the term a 'simple SMTP relay' a contradiction in terms?!I have an elderly Dell server on which I have just made a fresh install of 10.04 LTS server. I had 8.04 running on it for a long time, but I haven't tried an SMTP server before. It is a headless server with CLI (no GUI) and the latest version of Webmin installed.I have a basic LAMP server installed for a few websites using PHPbb and Joomla, and also I run a Mediatomb server for our household. When I installed I also chose to install mail services, but these remain masked behind NAT at the moment

I now want to set up an SMTP relay server so when I am working away and using different wifi points or my notoriously unreliable 3G dongle I can always send emails through the home server (from my iPhone and my laptop) rather than having to look up the SMTP server for each ISP of the place where I am working.

What I want is an authenticated server which takes my email and redirects it to my home ISP's SMTP server. I need only 3 authenticated users to have access (myself, my wife and my son). I don't need (or want) any incoming mail services at all.

Useful modules installed are: Dovecot, Postfix, Procmail mail filter, PAM - but how do I set them up?

Is there any simple setup that I could do, preferably through Webmin, but I can handle CLI if necessary?

I have looked at the Ubuntu help pages, but it looks so complicated to set up something that seems like it should be so simple to me.

Ubuntu Servers :: Relay Access Denied 5.7.1

Setup an Ubuntu LAMP server to house a Wordpress site. Everything is gravy but I am having some troubles getting emails to route outside my local network. I have setup Internet and also added my ISP SMTP as a smarthost - either way I get the dreaded Relay Access Denied 5.7.1.

I am using DynDns as I do not have a static IP - not sure if this makes a difference?

Ubuntu Servers :: Nullmailer Relay Through The Postfix?

Feb 21, 2011

I currently have a postfix / dovecot server running on one ubuntu server with nullmailer relaying webmail on a different server. This is currently working except the mail server is rejecting incorrect addresses which results in the messages being stuck in the nullmailer queue on the webmail server. Is it possible to force postfix to accept and manage all relayed messages from webmail, or is it possible for the nullmailer to manage the bounced messages correctly?

I have setup up an Opensuse as a simple we/application server.It handles requests for various things and will need to send out email on occasion for things like password reset requests, information / warnings etc. etc.This is a standard OPenSuse 11.x install with defaults so it comes with Postfix as the mta.I do not want a mail server I just want to send out via my clients mail server which is hosted exchange rackspace, which simply requires SMTP auth to do so.What would be the proper way to do this so ALL e-mail send from this machine, regardless of account like WWWRun or when logged in and sending from the command line has the same sender all the time.
