POSTFIX Installation/configuration

Does anyone know of a good postfix tutorial?
I'm having trouble getting it to work on my server.
I'm using Ubuntu 8.10.
I have a working SMTP but I need POSTFIX for php mail()
I recently moved to a VPS and installed Postfix onto it as my mail server. But I have following problems with its consistent working:
1. I experience that every now and then (once in 2 weeks) , it stops sending mails and put them in the mail queue with the following error:
Host or domain name not found. Name service error for name= type=MX: mysite.com not found, try again
I am not sure why it says so. However if I try to restart my mail server /etc/init.d/postfix restart and then try to flush the mails out of queue they are sent successfully. I am not sure where the problem is.
2. Secondly, I see that the header of my mails contains the hostname of my VPS machine "gospel" which is ofcourse not intended. How can I have my domain name in the mail headers?
I have my postfix server configured to allow me to send email without authentication whenever my ip matches a value in my config. Only problem is, i have it open to accept anyone in my subnet, and i'm kind of weary of letting anyone in this area send mail through it.
I have a script on my server that gets my ip address whenever i send an http-based request to my winamp now playing script. When it gets my ip address, it updates a file called ip.txt with my ip address. What i'm trying to do is config my postfix main.cf file to grab the ip from ip.txt, and add it onto the mynetworks variable. Then when i try to send the email, i want it to recognize me, and let me send the email.
I got and apt-get dependencies error while installing Postfix. At the end the log told me, to ask for free support - thats what I am trying to get here.
My system is Debian Wheezy with Plesk 12.0.18
How can I re-enable my Postfix?
Reset postfix configuration in plesk 12? I have some misconfiguration on smtp banner and hostname so I prefer to reset all.
View 6 Replies View RelatedI run a virtual server (Ubuntu 12.04, Plesk 12, Postfix 2.9.6) using plesk to manage multiple domains. The server address is server.domain1.com. I use plesk to also manage domain1.com regarding all services, including DNS and mail.
What I just found is that postfix sometimes issues the following warning:
server postfix/trivial-rewrite[7397]: warning: do not list domain server.domain1.com in BOTH mydestination and virtual_alias_domains
The essential part of my main.cf is:
myhostname = server.domain1.com
mydestination = localhost.$mydomain, localhost.localdomain, localhost
virtual_mailbox_domains = $virtual_mailbox_maps, hash:/var/spool/postfix/plesk/virtual_domains
virtual_alias_maps = $virtual_maps, hash:/var/spool/postfix/plesk/virtual
virtual_mailbox_maps = , hash:/var/spool/postfix/plesk/vmailbox
virtual_transport = plesk_virtual
And /var/spool/postfix/plesk/virtual_domains contains amongst others:
domain1.com domain1.com/
I do not have any issues with receiving or sending e-mails right now, but would like to get rid of the error message however.
Could it be the problem that postfix automatically sets mydomain to $myhostname with skipping the first part (i.e., mydomain is implicitly set to domain1.com)? Should I manually set mydomain to server.domain1.com instead? Any other recommendations? Since mydomain seems to be used in multiple options [URL] ..., I wonder what I might destroy with changing this? As all mail services run without any further troubles at the moment, I don't want to break this...
As I assume that quite some people use a plesk-based server to manage the domain to which the server itself belongs to, I would assume that there should be a general fix/check to updated mydomain accordingly?
I just installed a new server and I would like to transfer all virtual-hosts on new Apache installation.
I updated all IP addresses in each .config file and simply uploaded the edited conf files into new /etc/apache2/sites-available folder. I rebooted Apache, but through Webmin I can not see them on Existing virtual hosts list. Why? Do I need to manually re-add all the 30 sites?
My issue started ince a couple of months seemed to increase with update to Plesk 12.0 (though I can't guarantee it).I am using Centos 6.5, all updated. What happens is that postfix usage starts to increase without any apparent reason (during week-ends for example). Then postfix is not responding anymore.

i'm running postfix on my mail server.
Is it possible to make each user/domain only send out 100mails per hour or less?
I'm currently having trouble with Postfix. I recently installed some new web hosting software (ispCP) and so some new configs were written for all my software. Postfix was one of them and I can't figure out what's wrong with it.
Whenever I send e-mails to my server, Postfix denies it saying "Unknown address error 554: Relay access denied". The logs say NOTHING about it and I've been trying the old configs on Postfix and still nothing works.
Here are my configs:

I tried following the directions about 'The Perfect Setup' for SuSE 10.1 for my email server and finally got it to work, but now I am having issues with error messages!
In my /var/log/mail file I get tons of:
Jul 6 18:15:17 <server> postfix/qmgr[8226]: warning: connect to transport error: Operation not permitted
and in my /var/log/messages file I get tons of:

My server's running Debian Etch, Postfix and spamassassin.
Spamassassin works: it flags spam messages correctly.
Currently I have set it to discard messages marked as spam and messages that doesn't have a proper ascii header (Eliminates mail from chinese & japanese spammers). But how do I make postfix to move spam to "Junk" (or such) folder, not to discard it.
Current /etc/postfix/header_checks:
Code:
/[^[:print:]]{8}/ DISCARD
/^X-Spam-level: *******.*$/ DISCARD
I did found something that could help, but didn't know how to apply it to my configuration, and it seems to be Php code for ispconfig.
I'm having some SMTP server security issues. I am running Postfix on my Debian VPS and I am trying to disable Postfix from being publically used by anybody except those with webmail.
I read Postfix's configuration at Postfix.org, but I couldn't find anything that I thought to be relevent to this situation. Do any of you have suggestions or ways to fix this? Besides disabling e-mail all together?
As another detail, I'm running Postfix on its original config, not through a MySQL database config.
I've got virtualmin installed and configured and working beautifully, and I'm able to add email accounts and have them checked by dovecot. Now I'm trying to work the SMTP side of things, but I'm stuck.
What's happening here is that when I attempt to send an email through Postfix, it replies with 'relay access denied'
I've searched google and tried various things, but none of them have worked so far. I can post any configuration files you need. After I get this working, I get to add another domain and see if the settings work there too
I'm trying to iron out this huge bug with Postfix. Right now I am stuck in a hole. I am trying to disable Postfix from relaying e-mail sent to my server. When I send e-mail without "relay_domains", I get a "554 Relay Access Denied" error. When I supply a "relay_domains" variable to Postfix, I get "mail for example.com loops back to myself" for an error.
I was skimming over the Postfix docs and it said you can make these errors go away with a "virtual_mailbox_domains" or "virtual_alias_domains" variable. My config has "virtual_mailbox_domains" but still these errors appear.
Is there a way to fix this, or a way to disable Postfix from relaying e-mail?
I am running postfix on my server. This server is used by me only Here is what I want to do for this server:
1. Receive email: I want to receive emails for some of my virtual domains host in this server
2. Check mail: I check email by using a web client which install in the server
3. Send mail: I send email by using a web client which install in the server.
4. Don't want to let any remote user to send email through my server.
Here is my config:
alias_database hash:/etc/aliases
mynetworks_style host
myorigin $mydomain
inet_interfaces all
mail_owner postfix
mydestination $myhostname, localhost.$mydomain, localhost
mydomain example.com
myhostname mail.example.com
queue_directory /var/spool/postfix
setgid_group postdrop
unknown_local_recipient_reject_code 550
virtual_alias_domains somevirtualdomains.com
virtual_alias_maps hash:/etc/postfix/virtual
Is my server secure enough? Can people spam email through my server?
I see people suggest to use smtp auth or pop before smtp to increase the security, Do you think it's necessary to do so in my case?
I'm using Postfix as my mail agent. I was wondering how to forward incoming emails to a script.
I did a search in google and couldn't find anything relevant only this.
create a alias like this.
email@example.com: "| php -q /home/user/full/path/to/script.php"
But is not working not forward nothing. I have tried everything but nothing works and the logs not show me any errors.
I installed recently Postfix + Dovecot (yum) on a CentOS 5.1 test box. The configuration went OK, I can telnet on port 25, 587 and 465 with no problems.

i am confused about setting up mail server.
1.Postfix or sendmail or exim as MTA? which is best?
2. which SMTP/POP3 is best? dovecot or courier or any other
3. or which MTA/POP3 combination is easy and works best?
i am looking for easy installation so that i can use webmail and outlook for emails.
what do you suggest? and of course not commercial ones.
How can I change port of postfix?
View 8 Replies View RelatedI have a server which runs suse linux on it. Postfix is already installed on it.
But, the problem is i am not able to send mail using root. I mean using mail -v command.
I could see the following in mail logs. I know 2 files main.cf and master.cf are there.
Not, sure what to change and how.

I have postfix running on a backup mx server for a plesk box. The backup mx does a very good job of reducing spam and virus to my plesk box thanks to mailscanner.
The problem i have now is i have to manually update postfix transport and relay_recipients file everytime a new domain is created in plesk. Do any one know how i can create a custom script that will pull domain information from my plesk box and will update postfix on the backup mx server. Maybe a website with information that can help.
i can always set a cron to run the postmap command to update the tables but i will need to update the respective files (transport, relay_recipients) first.

View 1 Replies View RelatedI have been trying to determine if I should use Postfix or Exim for our new SMTP gateway. My biggest obstacle is in trying to determine if Postfix can handle the processing as efficiently as Exim.
Basically we have hundreds of domains that will have email going through the gateway. I need to know if Postfix can be configured to perform different actions based on the recipient domain (i.e. block receipt of message or add a header and deliver). It looks like this functionality is handled by using a 3rd party tool like "amavisd".
The problem is that it looks like I have to wait for the DATA to be received before I can send the mail to the filtering tool rather than just waiting until the last RCPT command. It is also unclear as to whether the message will be denied during delivery with a 550 error being returned or whether the message is accepted and a postmaster message is sent. Obviously I would prefer the 550 error.
I didn't know where to post this question since VHCS has no official forum (that I know of), so I decided to post it on sitepoint. I'm sure some of you use VHCS and maybe someone can help me with my problem.
I am setting up a hosting server for the sites I develop for my customers. This server is intended to host only websites (no email). The MX records for the hosted domains will mostly be directed to Google Apps.
My problem is that VHCS automatically adds all hosted domains to postfix as local domains. This in turn means that I cannot send email to these domains from the server itself (e.g. from PHP scripts).
I believe that local domains are listed in the file /etc/postfix/vhcs2/domains. Now, I could just delete them from this file and it would probably work, but I would really rather see if there was a way to convince VHCS to not add them to the list in the first place. There are several reasons I am reluctant to do this manually: I have extra work every time I add a domain; there is a chance I'll forget to do this; it says in the file "Please do NOT edit it manually", which probably means that VHCS will overwrite my changes at some time,...
Does anyone know, how to configure VHCS to not serve as a mail server for any of the hosted domains, bearing in mind that I cannot simply shut down postfix, because I need a way of sending email through PHP?
I have both sendmail and postfix installed. Which Should I install?
DK-MILTER-1.0.0?
or DKFILTER?
