View 10 Replies View RelatedI am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages.
2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.
Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.

I have a postfix relay running in RHEL 5. It serves as an SMTP server. Mail traffic is delivers to the exchange server/Active directory system that is handled by another admin. So far postfix serves [URL] I am asked if it's possible to configure the same server to relay inbound and outbound email for the domain [URL]
View 4 Replies View RelatedI'm running CentOS 5.4 with sendmail. My computer hostname is bob.domain.com. Whenever I would nc -v 127.0.0.1 25 into sendmail I would get bob.domain.com on the banner. Whenever I send out email the emails would be user@bob.domain.com. I wanted the email to show up as user@domain.com. So in the etc/mail/sendmail.cf file I changed the line
Code:
Dj$w.hostname.com
to this
Code:
Djhostname.com
Now when I enter sendmail I see domain.com in the banner so I know the change took place. However, when I send email using
Code:
mail -s "test" xxx@xxx.com
then email still goes out as user@bob.domain.com. What other changes do I need to make?
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
View 2 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.

I'm configuring a postfix server for the company I work for and have a question about limiting access by IP address.
First off, we're not using this for SPAM. We're a manufacturing/direct marketing company and will use the email server to contact our salespeople. We do not send UCE. That said, we have had problems in the past with our legitimate email being labeled as spam by a few carriers. This email server is being setup specifically to avoid future problems on that type.
Because of the nature of our business we operate several domains. We want to be able to limit outbound email for a given domain to a single IP Address. For example, say we have have 3 domains - a.com, b.com and c.com - and 3 IP addresses - 1.2.3.1, 1.2.3.2 and 1.2.3.3. We want to set things up so that a.com can only send out email on 1.2.3.1, b.com can only send out email on 1.2.3.2 and c.com can only send out email on 1.2.3.3.
My first impulse is to set these up as virtual domains on the Postfix server but I'm not sure that's the best method. Are there alternatives? What are your recommendations for doing this?
I am looking at setting up a multiple postfix SMTP servers for a single domain. Below is my requirement, I would appreciate if someone out there could guide me to achieve this using postfix..
1. Want to setup 2 postfix SMTP Server with 1 POP3 Server.
2. Server1 will host POP3 & SMTP services for domain "metallica.one".(IP: 1.1.1.1, MX: mx1.metallica.one)
3. Server2 will host only SMTP services for domain "metallica.one" (IP: 1.1.1.2, MX: mx2.metallica.one)
4. Server1 & Server2 will be used as load balancing for sending mails. (either manual settings in email client, or auto-loadbalancing is still preferred).
5. Mail received for domain metallica.one on Server2 should be pushed/forwarded/relayed to Server1 where POP3 services are running.
6. Outgoing mails for other domains from Server2 should be sent directly to the other-domain-recipients without relaying to Server1.
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

View 2 Replies View RelatedIm trying to get postfix to filter my outgoing mail and basically drop everything that is not in my hash table.
So far I managed to get this going
Code:
Code:
Unfortunately those rules also apply to incoming messages. My goal is to disallow users on my host to change their "MAIL FROM" to anything they like and restrict them to domains I specify. I'm aware that the local part still is variable and a user of domain "foo.com" could use a email of domain "bar.com", but still some of my troubles would be solved if I get this running.
I'm using Ubuntu Server 10.04 and I can successfully relay mail generated by php scripts through an Exchange server.What I want to do is accept incoming mail from the Internet through postfix and relay it to the Exchange server but I want all mail that is not addressed to ...@mydomain.edu to be discarded.

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
I have a mail server taking care of mail for my 4 domains; the first is used for virtually all mail, the second rarely used anymore, the third is virtually 100% spam the past year(?), and the fourth isn't in use (and never has been, so no spam). What I'd like to do is to reject all mail to the third domain. Right now this is what I get (I tried to send to a nonexistent address from gmail):
[code]....
Since my username (xyz@) is the same for all domains, I could (or so I hope) change the reject message to give a hint to replace [URL] with [URL] and try again.
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.
View 3 Replies View RelatedI've setup postfix using mysql tables and all works except for sending to an alias. The mysql logs show that postfix is only looking at the mailbox table for where to deliver the mail for the alias. However it is not looking in the virtual alias maps table. There are no complaints from postfix on startup to indicate that there is anything wrong, and if I send to a virtual domain listed as a relay on the server it does look up the virtual alias table... even though the domain is not hosted on the server....
So the question I have is where to look next? The mysql log shows the expected lookups from postfix EXCEPT for the virtual alias map queries.... why would it not be checking the table? Since it is not looking up the virtual alias it bounces the addresses back to sender complaining that the user doesn't exist... It does deliver to a virtal mailbox, however again it never checks the vitual alias table.... so it only delivers since there's a mailbox for it rather than needing an alias...
While in YAST2, everything seems to save fine except for the information in the "Host Name and Domain Server Configuration" screen. I have two servers side by side, the one works perfectly fine, the one does not. I can save the IP address and changes to DHCP and Static, but when I enter in the information for the Domain Name and Host Name, I click next, it saves, but when I go back in to it, the items I set are blank again. The boxes are not greyed out, you can type information in without error. When entering YAST, it requests the root pw which also works fine. I am not using any strange characters other than letters/numbers. I am going in to the screen by clicking network devices-->Netword Card-->Host Name and Name Server.
View 1 Replies View RelatedI have a server which runs postfix. The same physical server is running web and mail services for several (3) domains, which I have reserved for future use (nothing serious or valuable, just freetime activities). Server "physical" address (also static IP) is myhost.domain.com. Lets say the other domains it serves are first.fi, second.net ad third.com. I can receive mails OK sent to all of these, I have added those 3 "extra" domains to the mydestination line in main.cf. Sending e-mails also works fine, but the sender is [URL].. I want the sender to be firstname@first.fi
I tried setting sender_canonical_maps = hash:/etc/postfix/sender_canonical in main.cf, and sender_canonical contains:
user1 Firstname1@first.fi
user2 Firstname2@first.fi
and I run postmap /etc/postfix/sender_canonical, and e-started postfix. But if I send e-mail as user1, the sender becomes [URl].. so it re-writed the username part, but hot the hostname/domain part. I also tried setting smtp_generic_maps = hash:/etc/postfix/generic but the results were similar. What do I need to do to re-write sender for user1 (regardless of host/domain) to Firstname1@first.fi?
I have an OpenSuse 11.2 system that is running 2 BBS systems independently, both of which are capable of receiving smtp mail on prot 25. What I would like to do is set up Postfix on the OpenSuse OS to receive all mail for both those domains and then send the relevant mail to the correct BBS. I would therefore have Postfix listening on Port 25 External and the 2 BBS applications listening on different ports on the localhost address. At least that is the plan.
how to do this. I want to do it and still make sure Postfix is secure and not accidentally open up any nasty relay holes etc etc.
I am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.
I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable, sendmail.cf, virtusertable, local-host-names, sendmail.cf, and submit.cf and most of these files are empty (except the .cf files), and the sendmail.cf and submit.cf make no reference to the domain in question.
Here is the output from a sendmail test that was was not received. (Private data omitted of course).
sendmail -v xxx@yyy.com
test email from yyy.com webserver. please ignore.
