How would one setup a header_check that would discard all emails that have more than 6 words in it? Such as, if there are more than 6 spaces in the entire message it would be deleted? I cannot find this out but it would reduce my spam intake by 50+ a day.
View 2 RepliesI've a mailserver based on postfix. I'm queueing all the emails that have to be sent. After that I'm managing the queue with the output of mailq.
But in this way I'm just able to have this details of the queued mails: sender, receiver, size, time. There is a way to see also the subject of that emails?
is there any way to put Disclaimer words on every outgoing emails (both HTML and Plain text email)? ..

View 1 Replies View RelatedI am newbie to postfix. I added a new domain to my postfix server in the main.cf under mydestinations variable and the relay_domains file. Also, added this domain to my backend exchange server. When I send a test message from the new domain, my messages from that domain appear to be stuck in the "queue active". What does it mean when you are stuck in this queue? Does this mean that my backend email server (exchange 2003) isn't allowing messages from this new domain OR that the POSTFIX server still needs configuring.

When a user entered a wrong recipient address, it will take almost an hour for the user to get the "Recipient address rejected" email. What can be done to let the user get the "Recipient address rejected" email quickier.
View 7 Replies View RelatedI'm building a replacement postfix email server and I'm getting intermittant loss of sent emails; where: sometimes mail ends up at the recipient (a hotmail address) and sometimes not. Having an offsite relay (or posting directly to the internet) doesnt help either. (Although using hotmail itself as a relay always works despite logged complaints about unchecked ssl certs) Most dissapointingly the log files for the smtp transations are the same for successfully received emails as for the "lost" emails.

I've recently followed a guide I found online [1] and installed Postfix and Courier on my server machine. I can send emails from the server to any email address but unfortunately I can only receive emails sent from the server - it's only accepting emails sent locally from the host.

I got a weird postfix setup question? This is a separate server to the one I posted about earlier today.
I need to setup a postfix server which will accept emails for local know address (full addresses) and deliver them straight to the users maildir.
Any unknown addresses (however for the same domain), needs to be relayed to another server.
This is a bit of a special setup as there is no fixed Internet connection to the server. So the plan is that local email get delivered straight away whilst emails to the same @domain, but that doesn't exist in the user tables get put in the hold queue and is later relayed to server number 2 when a connection is available.
I am using mysql to retrieve all my settings into postfix.
I have a server with a domain running and im trying to resolve the mail server but i can't see where to start. I use OpenSuse 11.2. Basically, for starting, i want postfix to send incoming emails to a php script or perl. for outgoing emails i guess that i could use php mail function and i will see what else to have. I configured the dns. I do a dig.mydomain.tld MX and i get the following:
mydomain.tld3600INMX0 mail.mydomain.tld
mail.mydomain.tld 3600INAmyNumericalIp
So now my system is receiving MX content but i dont know what to do.
How to seup nagios to send email to mails in MS Exchange server ?
View 3 Replies View RelatedI tried searching the posts and have come up empty handed. I need to find an email I sent to myself (actually a forward of several other emails) that did not get delivered. Otherwise I need the original emails themselves. I have been using pop with dovecot on my ubuntu server Jaunty machine. I searched the mail logs and found that the reason the message might not have been delivered could be because my permissions were not set to administrator for that user. I changed the permissions and still nothing came back.
I deleted the client mail account on the machine I used that had the messages but I was hoping they might still be somewhere on the server. Any ideas?
just followed the guide on how to setup Ubuntu 10.04 server + postfix from here: [URL]..ports 110, 143, 25 are forwarded on my router to LAN IP of mailserver.
postfix settings
hostname: server1.mydomain.com
example email: user@mydomain.com
I can receive emails in outlook, if they were sent from the mailserver using: mailx user@mydomain.com
However, external emails from hotmail.com to user@mydomain.com never arrive. I'm thinking this is because of the DNS host records for my domain. Here's what I have.

CentOS 5 box was just setup to replace a crashed old one. I have postfix.admin installed and working, added users (confirmed from mysql command line) and can login using telnet server pop3 with the user information. The problem I am left with is just receiving mail. I have both squirrelmail and roundcube installed, and can also authenticate using both (/var/log/maillog shows);From either webclient I can naturally send mail out and both yahoo and gmail client confirms, yet a reply shows nothing, and nothing ever shows in the maillog. Firewall is shut down but I don't know postfix enough to see how to test, or is something else grabbing the mail.
I can provide anything necessary, just let me know what. As I see it (just so far) Postfix should be the server that answers and receives the mail, dovecot is more the pop/imap the client would use, so I think it's a postfix issue. If so, can I turn up the debugging, etc. but again, I think all mail received should appear in the maillog file 1st as I see the outbound mail go fine!
How can I setup "reverse dns check" option in Postfix ?
View 1 Replies View RelatedI have a Postfix+Dovecot and virtual users setup taken from here. I've got virtual users authenticating using a password file. But I'd like to lock the service down further, so authenticated users can only email other authenticated users (those listed in the same password file) - so it's a closed community. I don't seem to be able to stop authenticated users mailing outside the community.
View 2 Replies View RelatedIt wasn't too long ago that I discovered Linux/Ubuntu (in terms of actually USING it) and I've been completely blown away by the capabilities it puts in the user's hands! To think that someone can take an old desktop from a trash pile (literally, in my case) and turn it into a web server for ZERO dollars is absolutely crazy.
Anyway, I've been using said desktop as a sort of "dummy" machine to learn Linux. I want to be clear that I've got another computer for personal use and that I understand that setting up server software on any computer poses a security risk. Having said that, I have a few questions regarding mail servers and their setup on Ubuntu. Again - I'm comfortable with what I've done so far in Ubuntu (installing packages, terminal interaction, basic usage)
My question is mainly this: if you have, say, a domain name through DynDNS (let's say example123.com) and it points to an Ubuntu system, does something like Postfix enable you to make your own email addresses such as user1@example123.com and have an email server from wherever the Ubuntu system is?
I've been following the basic Postfix setup here and have had success so far (down to the "Adding your local domains to postfix" section) bu wanted to make sure that what I'm intending to do is what I'm doing (haha... i hope that makes sense). That is: get domain name at DynDNS, host pages on LAMPP server, use Postfix to facilitate incoming/outgoing email for that domain name.
I have set up a couple of postfix servers for my domains, but the only thing I am missing now is this: How to block the public sending mail from my email to my email? I have managed it with SPF, but surely there must be a better way, that returns "relay not allowed" to the client. The SPF method costs too much, since it must make a dns request for each mail. So far, I have not gotten many of these mails, unless when testing my mailserver, but as I see it, anyone should not be allowed to send mail from abuse@mydomain.com to abuse@mydomain.com.
Somebody must have thought about this a long time ago, and there is simply that little line in main.conf that I'm missing.. My setup is this (virtual): I have a primary mx, with postfix, courier IMAP/POP3 server, a user database, and sasl via saslauthd. I also have a secondary mail server (backup mx) with no sasl auth, but with a copy of the mail users in the virtual tables, but added as relay_* users instead.
Spamassassin and SPF testing is replicated too, so most of the stuff should work, but I simply cannot find a setting in Postfix that denies someone to mail FROM my address TO my address. When mailing from my address and out in the open, they are required to authenticate, but not when using one of my my domain addresses, and also targeting my domain addresses.
As said, It is possible with a strict SPF setting, but that is at a cost for every lookup. It would be quicker for postfix to lookup the sender and the recipient in the relay/virtual tables, and deny if both addresses were in the recipient tables, and sender is not authenticated.
I have setup postfix and postfixadmin on a CentOS 5.5 server and the install appears to be ready to go. I have never used postfix and postfixadmin and I am having a hard time finding any documentation on how to setup and administer the postfix server with Postfixadmin. This is simply a test and alerting server and will not be hosting user mailboxes. I am only looking for the basics I am not going to need to setup anything complex

2. Do I need to forward any particular port in my router?
3. If I dont have a fully qualified domain, what are the configurations I need to do to send emails?
