Jan 18, 2011
i have configured mail server with postfix with dovecot with no encryption:When connecting with Thunderbird imap is working fine. when sending email from another domain to this domain again it is fine. but when i want to send mail frommy domain to another it gives me error and this is /var/log/maillog:
I have configured mail server with postfix with dovecot with no encryption: When connecting with Thunderbird imap is working fine. When sending email from another domain to this domain again it is fine. But when I want to send mail from my domain to another it gives me error and this is /var/log/maillog: Quote:Jan 18 18:23:09 srv1 postfix/smtpd[3991]: NOQUEUE: reject: RCPT from unknown[95.81.67.120]: 554 5.7.1 <Recipient email>: Relay access denied; from=<Sender> to=<Recipient email> proto=ESMTP helo=<[127.0.0.1]>
My postfix is ok with receiving emails but i can send mail to my domain only [URL] When I want to send to other domains i receive this error (in the maillog):
my server is Redhat as 5 + postfix +Dovecot .when i use smtp to send mail，it can't to send,the system return "relay access denied" ? This is my maini.cf
Code: # Global Postfix configuration file. This file lists only a subset # of all parameters. For the syntax, and for a complete parameter # list, see the postconf(5) manual page (command: "man 5 postconf"). # # For common configuration examples, see BASIC_CONFIGURATION_README
Postfix is not sending mail, I did a basic test of sending an email locally using the Linux mail command, and nothing was delivered, and I couldn't find an error either.
Where is the log for postfix located?
In main.cf I changed: myhostname mydomain mynetworks home_mailbox (I want to use Maildir/)
i have been working on setting up an email server over a ddns. All seems to be working (i can email me@my_ddns_domain.com to me@my_ddns_domain.com) except that when i try and send to another email address (some_other_me@other_host.com) i get the error "5.7.1 Relay access denied". The way i tested this is as follows: Code: me@my_ddns_domain:~/$ netcat my_ddns_domain.com 25 220 my_ddns_domain.com ESMTP Postfix (Ubuntu) ehlo localhost 250-my_ddns_domain 250-PIPELINING
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.)
One of my mailservers running postfix has suddenly stopped sending mail and has been generating the following errors:
Jan 7 12:03:08 postfix/sendmail[3560]: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name Jan 7 12:03:08 postfix/sendmail[3560]: fatal: root(0): unable to execute /usr/sbin/postdrop -r: Success
[Code].....
Things I have tried to fix this problem, but didn't work.
1) Stopped postfix, uninstalled and reinstalled.
2) Did a complete filesystem relabel with a touch /.autorelabel and reboot.
3) Did a restorecon -F -R on /etc/postfix, /var/spool/postfix and /usr/sbin/post*
Nothing above has worked and have no idea why with selinux disabled postfix works and with it on it fails.
I'm a bit lost with the PHP/Sendmail configuration, maybe somebody could help me getting back on the right track. Following situation:
Postfix:
* accepts smtp on port 25 but from his own domains. Some policy and spamchecks through amavisd are made.
* accepts submission on port 587 and 465 from authenticated users only. Quota and spamchecks prevent outgoing spam.
So I'm enforcing a very strong outgoing spam-policy but the users are still able to use the php mail() function to send spam through the /usr/sbin/sendmail command. My users have access to their own php.ini so my idea was to somehow enforce the delivery through the local postfix on port 587 or 465 and just let them enter their user/pass in their php.ini. (I suppose, their might be a cleaner-solution ).
Unfortunately, my configurations like smtp_host, port, user etc. are getting ignored if the sendmail_path line is active. But if I comment this line out, php just uses the default, which is the same as configured in the sendmail_path line - so it's active whether i use the line or not (setting it to an invalid command breaks the mail() function completely).
how can I enforce my anti-spam policy on the php mail() command?For my ssh users I just blocked the outgoing connection to localhost on port 25 which seems to work so far, but somehow the postfix-sendmail-wrapper just ignores this.
Two 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 installed FC10, and configured everything to work with my static IP address [URL]. As far as email goes everything works except for the php script on my website. This script worked fine on my previous install, and it appears to actually submit the email as shown in the maillog:
Aug 12 14:21:02 myhome postfix/pickup[27581]: 37406BFDD9: uid=48 from=<apache> Aug 12 14:21:02 myhome postfix/cleanup[27783]: 37406BFDD9: message-id=<20090812192102.37406BFDD9@www.myhome.com>
[code]....
I also created the following php script to test
<? (mail ("test@myhome","Test message","this is a test")) ?>
And I was able to send successfully with this script with the only difference being it was sent by root rather than apache. This leads me to believe it's some sort of rights issue with the apache user. I wouldn't be surprised is SELinux was behind it all. I spent days and days after installing wordpress trying to get it to connect to mysql, and that turned out to be a SELinux issue.
I have an issue with postfix and my server.One account (mine) is not considered as spam by no one. But all the other users are treated as spam by yahoo, and hotmail. And I can't understand why.Here are the header from one user who sent an email to my yahoo account (treated as spam):
Code: From userNAme Sat May 22 01:52:27 2010 X-Apparently-To: me@yahoo.ca via 98.136.183.25; Fri, 21 May 2010 14:52:55 -0700
I set up my mail server using the guide here: [URL] I am able to receive mail, I can send mail locally, but I can't send to external addresses. This is in my mail.log: Quote: Jun 30 14:40:43 Server postfix/smtp[10725]: 2FD9322015BF: to=<myemail@gmail.com>, relay=none, delay=1634, delays=1484/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.65.27]:25: Connection timed out)
The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:
When attempting to check my postfix install by using telnet to send an email to an address outside my local network, I get a relay access denied error.
This is how I attempted to send an email
Code: telnet my_server 25 helo my_server mail from: me@my_server rcpt to: me@gmail.com
This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
xx@xx.com SMTP error from remote mail server after initial connection: host [URL] [ip address]: 550 Access denied...
how can i configure my server to send mails from about ten different domains i use google apps and want to know if its possible. Because it sends mail but all goes to spam and i have a static ip
I just setup a mail server on my web server and I cannot for the life of me figure out how to send emails to external (as in outside my LAN) emails or receive from external emails. I'm using Postfix with Dovecot and Squirrelmail. I get this delivery report in Squirrelmail when trying to send an email to my hotmail address.
Final-Recipient: rfc822; example@hotmail.com Action: failed Status: 5.0.0 Remote-MTA: dns; mx3.hotmail.com Diagnostic-Code: smtp; 550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. [URL] maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit [URL] for email delivery information and support.
I'm not sure if this is a server problem or a PHP problem. I've tried the code on other servers and it seems to work - so I assume it's a server problem. I am running it on Ubuntu 10.10.
When run this code, it does not render in HTML on my OSX mail reader:
PHP Code:
<?php$to = "xxx@xxx.com";$subject = "HTML email";$message = "<html><head><title>HTML email</title></head><body><p>This email contains HTML Tags!</p><table><tr><th>Firstname</th><th>Lastname</th></tr><tr><td>John</td><td>Doe</td></tr></table></body></html>";// Always set content-type when sending HTML email$headers = "MIME-Version: 1.0" . "
I have a problem relate to posttfix.I want to mirgare postfix mail server to exchange 2010 mail server but I can't do it,u can help me.You can show me have to do configure postfix and exchange how to?
I am trying to install a mail server (postfix). I followed the instructions (up until SMTP, I do not want that) on ubuntu pages, without any result. I can send mail, but I can't get any.
I'm having a problem with my webdav share. I have a secure webdav folder that gets accessed via a non-standard port and requires basic authentication. I can connect and interact with it fine via cadaver. However, when I try to connect from nautilus, it says "Access was denied." To make it even stranger, sometimes I can click on the folder in nautilus (it still mounts) and access it. Sometimes not (just repeats the error message and won't show me the contents). I may not even un-mount it, but just look at other folder, then click it again and be able to access it, but again - only rarely.
I asked a friend to try connecting from his windows vista computer and it would not work. It would not work from my windows XP virtual computer either. However, it mounts and works just find from my work computer (also Windows XP).
So it seems to be a 50/50 chance that the drive will mount on any given computer/system and work. Do anyone know what the problem may be? I'm guessing user permissions, but I can't figure out what.
I've made sure the webdav folder is owned by www-data and www-data has read access to the password file as well.
When I try connecting from nautilus, I get this in the log file:
Code:
Here is one of the (many) sites I've tried looking at: [url]
at first, sendmail was installed and everything was working great. all the email sent from forum and webform I host as been sent correctly in the reception box of the recipient. But I want postfix as MTA to do my delivery to all my virtual domain I host.
when sendmail is uninstalled and postfix installed and all services configured(php included) and restarted(apache included), when I send a email from command line or from web form, the email goes in junk mail for some ISP email address and for gmail and the email did'nt show at all for hotmail. but email sent from forum (phpbb) still goes in reception box like normal email do.
I tried do change the headers, who was working with sendmail, of the email sent from web form without success.
so I tried to uninstall postfix and reinstall sendmail, restarted all service and every thing was back to normal... email sent goes in reception box.
I tried it twice.... sendmail, postfix, sendmail, postfix and now back to sendmail for a working solution until I get postfix working.
I tried with spf entry in my dns, I tried allowed icmp packet from outside with iptables, I tried many different headers for my email. My ip is not blacklisted anywhere.
