I'm having a problem with a new install of postfix... it won't relay mail to external domains. Internal mail is fine.I'm using virtual_mailbox_domains so that I can have multiple domains, and I've set dovecot to use local files with encrypted passwords.Here's my main.cf
Code:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
[code]....
i have configured postfix to deliver mail from an internal mail server to external domains... however i keep getting this errors
Code:
un 10 23:23:59 smtpserver postfix/local[28831]: 7800CF0058: to=<root@smtpserver.domain>, orig_to=<postmaster>, relay=local, delay=0, status=sent (delivered to mailbox)

I have Postfix + Unix Accounts + Virtual Domains. I have a bunch of domains hosted on my machine, let's call them [URL] [URL] and [URL]... etc Until know, domain2.com, domain3.com were mapped in virtual domains to [URL] So this is how /etc/postfix/virtual looks like:
[URL]
Like I said, all mail accounts are unix accounts, so, if for example I have the user "paul" this user will receive e-mail for ALL DOMAINS. [URL]But as it turns out, I now need a COMPLETELY ISOLATED domain... let's call it [URL]. So If I create a new user, let's call it "steve" I want steve to receive e-mail ONLY on [URL] and not on all others.
I would have to redo the whole thing from the beginning. I'd have to comment out the $mydestination parameter in the main.cf file and start using only virtual domains. So if I have the following users: paul, steve, sally, megan, jenny and I want paul and steve to ONLY receive mail for domain1.com, sally and megan to receive mail for domain2.com and jenny to receive mail for domainX.com, my /etc/postfix/virtual file would have to look like this:
[URL]
I'd have to create the unix account and then start modifying the /etc/postfix/virtual file.
setting up DKIM AND POSTFIX FOR UBUNTU 9.10 WITH VIRUAL DOMAINS
View 1 Replies View RelatedLet 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 have a setup wth postfix, dovecot and sasl. It is setup to relay all my email through my gmail a/c mainly because my port 25 is blocked by ISP. I just setup postfix and dovecot with ssl/tls and according to docs I read it will now be connecting on port 465 for smtp. If I need to test if my setup is working do I need to change anything anything other than commenting out the relay line in main.cf. Am hoping I don't have to deletehe sasl_password file in case I need to revert back to old setup.

However, I can't send email to external domains (like gmail, yahoo, etc) different than mine. I've tried sending from a remote connection using Evolution and I get the following message on mail.log

When I use sendmail (or, most commonly, a PHP or Perl script uses it) to send to any other domain except my own, it works great. When I use it to send to my own domain, however, it's trying to deliver it to localhost. Problem is, all our mail is handled by an Exchange server on a different machine, so I really don't want If I run sendmail manually for a test message to myself, here's how it comes up after the message is closed out:
Code:
echo "Subject: test" | /usr/sbin/sendmail -v me@domain.com
354 Enter mail, end with "." on a line by itself
>>> .
050 <me@domain.com>... Connecting to local...
[code]...
The message then gets dropped into my box at /var/mail/xxxx, but that's really not helpful to me -- I need to to connect to that other machine to deliver the mail there. This machine isn't used as a mail server at all. Also, if it's trying to send to a username that doesn't have an account on this server (we have many), it just fails entirely with "user unknown" (that makes sense, as there are only a couple of user accounts on the web server). how to get sendmail to connect to our mail server instead of "local"?
Does anyone know if it is possible to set up Postfix to receive all email coming to mydomain.com and forward them to 2 different spam filters? All mail needs to go to both spam filters then onto our Exchange server
View 1 Replies View RelatedI have a RHEL 4.5 with Postfix 2.2.10 configured as a smart host for an Exchange 2003 server. Its been running well for three years like this. We have some users that are configured with alternate SMTP addresses for a secondary email domain in Exchange. One user is not getting his email for the secondary SMTP. All the others are. After some digging, the maillog indicates Postfix is not relaying his email to Exchange but to the Postfix local mail folder under /var/spool/mail. What in the configuration would cause this? His email is in the relay_recipients file as the others are.
View 1 Replies View RelatedTwo 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.
i have setup mailrelay using postfix and relay email to exchange server. The problem is how can i relay email to multiple exchange server. For example: -
domain aa.bb.com relay to exchange server 10.10.10.10
domain 123.test.com relay to exchange server 192.168.10.5
I have been running an email server on a Red Hat 9 system for 5 years, and wanting to upgrade it to the latest Fedora OS. A few days ago it crashed. The server is running Fedora 11 (up-to-date). Clients are Fedora 11 and Windows XP machines using Thunderbird for accessing email. The server is running Postfix and Dovecot. Within my local network I can send and receive emails. I can also send email to addresses outside of my local network. The only problem is that I cannot receive any email from outside the local network. I cannot think of anything aside from my firewall (iptables) or postfix config that could be causing the problem.
Below are my iptables file, and the postfix main.cf changes that I have made.
Iptables (the same file I was using on Red Hat version 9 with one minor deprecated syntax changed):

who manage Postfix servers, what do you recommend is the best way to refuse all incoming and outgoing mail to specific domains? I want a blacklist of domains such as:
- AOL
- Yahoo
- MSN
- Hotmail
- Gmail
Is there a proper way I can tell Postfix to please deny sending and receiving SMTP traffic to and from those specific domains I specify? I see no need in my corp. mail server has to communicate in any way to those. I allow access to all those accounts via port 80/443 so they can just login to the web and send non business related junk this way.
I have a postfix mail server up and running. I've added more than one domains to recive mail by adding them to the :/etc/postfix/virtual and poiting to a UNIX user account. That works fine. But when users send out mails (From squirrelmail) all users send from the same domain. How do I add a $myorgin to a virtual domain?
View 1 Replies View RelatedI am setting up a Postfix MTA that will be only sending mail for 10 different domains. We have other servers that will be receiving the mail for the domains so I only need to set up for sending on Postfix.
What my issue is I am trying to configure Postfix so that when it sends mail the header shows what domain the mail came from and not the domain the Postfix server is set to. For example....
[URL]
When I send mail from domain2.com I want it to show in the header it was sent from domain2.com and not from domain1.com. What do I need to set in postfix so that this happens? Right now no matter what domain the mail is from the header always shows the server domain and I can't have that.
I am running a spam filter on debian lenny 5.1 with postfix, amavis-new, spamassassin, and clamav. It works pretty well but I would like to finish tweaking it to minimize the mail getting quarantined. It really isn't quarantining anything that isn't spam, except for an occasional list mailer. However, the quarantine is huge, and takes a while to go through. I noticed that much of the spam is coming from foreign country tld's like .cz is there anyway to have postfix run a check on the header and if the email, or smtp origination is from a server from a foreign tld have it just rejected. I can whitelist anything if need be in the future but as of now we don't do any business overseas and don't need to worry about blocking legit email.
I think this should be possible, however, I am unsure of the syntax for the file, where to put it and if wildcards are possible in domain blocking like
Code:
*.cz REJECT
I would like to set my postfix to reject any numeric domains. I am seeing in my mail queue mail from domains like 2212.com, 263.com, 29.com and others. Because there is a variety of these, I don't want to track each of them and block them one by one. What do I need to put in my access file to reject any numeric domain? Is it possible to have a numeric wild-card reject in the access db?

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.)
I am currently running a apache/postfix email service on my server. I am using aliases for two addresses for example:
trscookie@serverone.com
trscookie@secondserver.com
so the emails no matter which domain receives the email trscookie always will receive the email.
However I am unable to work out how to 'reverse' this process, for example.
If i was to go to secondserver.com/webmail I would like the emails to get sent from trscookie@secondserver.com however they are currently all coming from serverone.com. Is it possible to configure this so that it is sent from the correct domain?
Here is my main.cf:
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix

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?
To start off, I realize this type of question is very hard to answer and there is no general rule. My intention is to merely get an understanding of what others are doing. Models: 1) small piece of a big pie, but many small pieces 2) big piece of the pie, but few pieces. Which model do you guys do? If one can make $100 from a site which little or know effert, why not create 100 sites like it? Benits: diversified with multiple revenue streams, hard to manage so many etc etc. OR Work hard on 1 site, focus, narrow the niche and make loads of profits. drawbacks: all eggs in 1 basket Which model do you guys employ?
View 2 Replies View RelatedI've built a web hosting server with ubuntu 9.10 desktop edition at home and it's up and running.how to get and set subdomains. What I mean is that I have a purchased domain [URL] and I want to add as many sub domains as I want such as [URL] so on. And more importantly every single subdomain must belong to each account.
sub domain account name
-------------------------------------------
sub1.example.com john
sub2.example.com steave
sub3.example.com myname
In this case, there are three accounts for ubuntu and each account has a permission to the corresponding sub domain only. p.s My DNS is managed by my domain company and it provides a web page where I can forward(not sure, but there are fields that I can type my sub domains) subdomains and my external IP addresss up to 20(just in case this info matters).
I've tried to set up an old laptop with Ubuntu server - need to use it as a web server for a group of students on a local network only. I managed to get it working fine for just one user publishing webpages etc to a folder called VAR/WWW I could FTP files into the folder and access them again via FTP or a browser. I then decided to create some subaccounts (one for each student) I did this by typnig the following commands:
Sudo usermod -g www-data student1
Sudo chown -R www-data:www-data /var/www/student1
Sudo chmod -R 775 /var/www/student1
(In this example student1 is intended to be a subfolder of www and act like a sub-domain with write authority- at least that was my intention) Problem I then get is that if I use Filezilla to access each account I cannot see where to publish the files - wherevever I place them they are not accessible from the browser. Do any of you experts out there know the answer to my problems please.
