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.
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'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
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
I 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.
I have an odd issue with postfix 2.5.5 trying to relay email internally to a range of mail servers and it keeps ignoring the transport map [ ] and instead always doing mx lookups.
Essentially the server is only allowing connections from an internal network and only for certain domains that it will relay to other mail servers.
It has no local delivery and yet every time I get email passed to it, it will check the local network DNS server for MX information or with diable_dns_lookups enabled (as below) the A record for the domain, and try to deliver to that instead of the transport map destination.
Here's the main.cf # See /usr/share/postfix/main.cf.dist for a commented, more complete version smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no disable_dns_lookups = yes # appending .domain is the MUA's job.
I have a Ubuntu server running in my house.Server name UshaMain PC name HomeLaptop 1 Named BooLaptop 2 Names Bobevery one is running Ubuntu 9.10The server is running Bind9 and Samba and is working from any other PC i can type ping usha and it will give me teh ip address of the server.This has been working for 4 months now.I just installed PostFix and nowthe only PC that is working with i ping the name USHA "server name " Is the server.The other three pc come back with the IP address of the domain for USHA.I have removed the Postfix from the server but the DNS is still not working for the other pc on the network.Ho do I get Bind working again form the rest of the PC.
I can ssh to my server which is on a LAN accessing the'Net through a Linksys modem/router.I want to be able to configure the Router by using the it's web interface, but the server only has a Command Line Interface and I can only run text browsers like Lynx,hich, although I can log onto the router, the Javascript routines mean that I can't configure the router.I can't access the router's web interface from the 'Net because the router is set up to pass any requests on port 80 to the server.Is there any way I can communicate with the router by sending HTTP requests from my browser external to the LANhaving these relayed to the router by the server and then the server relaying the responses back to my browser.
I'm just getting started with postfix for the first time (using courier pop) and everything is working well. However I can't seem to figure out how to only allow some system users to have mailboxes?
For example I have a few accounts which are FTP only accounts but they still have mailboxes under postfix? Is there any way to tell postfix the accounts that I actually want mailboxes for?
Also on a side note, I notice that mail seems to be stored under the user's home directory. I'm scared they may accidentally delete them.
is there any HOWTO for configuring Webmin Postfix server with multiple postfix virtual hosts? Seems to be a tough challenge to set it up without any easy manual..
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 recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile. Here is also the cat of my makedefs.out:
I am using postfix as spam Mailscanner to protect my mail server running sendmail. The problem is that when I forward an email from MailScanner mail me back with the following error:
<postmaster@localhost.@mydomain.com.>... Real domain name required for sender address (in reply to MAIL FROM command)) Jul 27 13:15:59 smtp postfix/local[28465]: C68AC1000001: to=<root@smtp.mydomain.com>,
my postfix to send and recive external emails, but many recive in trash folder.Other programer say me that is need some configurations in postfix with and dovecot to work, but i dont know what!This is my first time configuring a linux server at this week.
my main.conf sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
i need to configure postfix on centos to relay email from the internet to the Exchange Server and i also need that emails sent from the exchange within the same domain be sent to postfix then resent to exchange because i have spamassassin and clamav installed on centos to filter all incoming and outgoing mails ...
I did a a basic install of postfix and dovecot instead of using courier-pop and courier-imap. This is only send and receiving e-mail locally within the test network 10.7.0.X and 10.0.0.X. I used:
[URL]
my postfix.conf is;
PHP Code:
[code]....
This is the error when I send an email from a local machine on the 10.0.0.X network.
PHP Code:
Jan 20 17:05:48 testbox postfix/smtpd[2491]: warning: Illegal address syntax from unknown[10.0.0.111] in MAIL command: <test@10.0.0.112>
I've got an uber simple test mail script in php on my awesome new dev machine running Ubuntu:
PHP Code:
Unfortunately, something is preventing mail delivery. I can't tell from this error log whether it's the remote machine rejecting me or whether it's my machine rejecting the self-signed cert on the remote machine:

I'm wondering what I could change in my postfix configuration to remedy this problem.
I tried setting smtp_tls_security_level = may = may but this did not change anything.
i compiled and install postfix, and i using relayhost that point to my ISP. but my "DNS server" is on the same server where is installed postfix. and there is running apache with vhosts so i have domain that hosted on same server and in zonefiles of my domain my MX records points to Google Apps, to google's MX servers. But when i try send E-mail via sendmail to mail@mydomainonsameserver.com it not deliver mail to Google Apps totally, if i try to send to another E-mail everything fine it deliver it. so finally i done research this problem in Internet. And find that need to disable deliver mail to localhost(localdelivery)as i think postfix understand that the domain point to the same server where postfix have itself. and try to deliver mail local. but zonefile MX record even the domain on same server can point to another server outside. So i disabled localdelivery in postfix. and problem not fixed
I am running CentOS 5.4 and Postfix. So when I start Postfix server than immediately maillog is starting to grow. And the first lines that I see in it are:
[Code]...
Server is already in several blacklists and I desperately need to do something.
I am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.
I recently had the need to relay SMTP mail through our organizations hosted MS Exchange server. I had to do a little troubleshooting, so I wrote a concise summary of the procedure I followed.
I 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.
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only.I had follow this how-to http://www.linuxmail.info/squirrelma...o-in-centos-5/ and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works.I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, i install VM player on it and run CentOS inside the VM Player.I want to do testing on Windows 7 side by installing Thunderbird email client program, i want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How ?
Do i have to do any other configuration on CentOS ? any DNS ? port number for IMAP,POP3 or SMTP ?
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.
I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.
My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.
I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.
I have been trying to set up a home mail server with postfix ever since I can remeber. Im yet to find a good tutorial for this. I dont have a static ip address or anything so this has to be done with the help of dyndns free account. good and convincing tutorial in order for me to do this. OS- Redhat5 or fedora
