Server :: Zimbra - Restrict Mail Sending For Subdomain?
May 4, 2011
I am having trouble configuring Zimbra to restrict sending for some users. A subdomain has been added in the ZCS web page for the domain, resulting in two potential mail addresses:
The subdomain needs to be restricted from sending mail to the outside world and to other users on the same subdomain. It should only be able to message users on the main domain. The users on the main domain should be able to email anyone in the world. Is it possible to configure this without installing Zimbra on two machines?
I want you help me to configure the Zimbra mail server. I want install system mail server Zimbra, about 8000 user then How configure server ?( RAM, CPU, HDD) (account email 100MB - 300MB). forward to the help from everyone and Administrator Linux
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.)
I'd like to have anything that tries to send mail locally on my machine (including crontab reports for instance) to be handled by my ISP's smtp server instead of my machine acting like it's own SMTP server. I've spent around 15 hours trying to figure out how to do this and I keep either getting into things that I don't understand, or hitting brick walls (for instance, I found nullmailer, but after installing it, it seemed like it would only work on Unix) Is there an application like nullmailer which I can use as my MTA to forward all internal mail to a different SMTP?
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: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name Jan 7 12:03:08 postfix/sendmail: fatal: root(0): unable to execute /usr/sbin/postdrop -r: Success
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.
Sendmail isn't sending mail for some reason and keeping it in the Queue. I attemped to flush them but it deferres the connection to the server in which it is trying to relay the message to. I have checked to see if there is a DNS error or anything like that. I attemped to flush the messages through webmin.
This is the result.
I am not finding anything in the logs to let me know their is an error. I can ping the mail servers that it is trying to send to. Now it has started delaying when ping MX servers. So I knew something was starting to mess with it. I have checked the /etc/hosts. It is correct. The server isn't black listed. Mail to root just gives me.
My ISP blocks outgoing email if it does not login properly with a valid account. I successfully configured sendmail to use SMART_HOST and confAUTH_OPTIONS with confAUTH_MECHANISM set to LOGIN PLAIN.
It successfully sends email because I tested it with evolution sending through 127.0.0.1, but I need to specify firstname.lastname@example.org as the email address for root.
But it doesn't work for logwatch because it sends as from email@example.com, and my ISP's smtp server rejects it. The message I get back in root@localhost account is the following:
----- Transcript of session follows ----- ... while talking to smtp.mydomain.com.: >>> MAIL From:<firstname.lastname@example.org> SIZE=581 AUTH=<> <<< 550 5.7.1 Client does not have permissions to send as this sender 554 5.0.0 Service unavailable
I thought that I should masquerade all emails from this domain, so I configured sendmail as specified in  section "126.96.36.199. Masquerading", but it doesn't work. It seems that masquerading in sendmail is broken or something is wrong in the documentation.
I have sendmail 8.13.8-2 and centos-release-5-4.el5.centos.1.
Is there a way to specify the "From:email@example.com" in logwatch ? or Is there a way to make it work the masquerading in sendmail so I can masquerade everything as coming from a specific account?
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: NOQUEUE: reject: RCPT from unknown[188.8.131.52]: 554 5.7.1 <Recipient email>: Relay access denied; from=<Sender> to=<Recipient email> proto=ESMTP helo=<[127.0.0.1]>
in Lucid ive been trying to get the mail applet to light up green by sending myself mail. Does this applet only light up when IMs r received or does this also work with evolution and if so what might i have done wrong in evolution, ive tried it with evolution open and evolution closed.
I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
I have two servers relavant here: mail.domain.com (184.108.40.206) - which is the nameserver and the mail server for domain.com. www.domain.com (220.127.116.11) - which is the www subdomain for domain.com domain.com (cname www.domain.com) - an alias for www.
The zone file for domain.com lists mail.domain.com as the MX server for domain.com. 18.104.22.168 is actually being served web pages as a virtual host. It's real hostname is www.anotherdomain.com. Mail for domain.com works pretty well, in general. However, if I attempt to send mail from www.domain.com (or its alias domain.com), I get "mail for domain.com loops back to myself" in the postfix logs. On 22.214.171.124 /etc/postfix/mail.cf has mydestination = www.anotherdomain.com, localhost. How do I tell postfix on 126.96.36.199 that mail for domain.com needs to be delivered to mail.domain.com?
BackgroundI have registered a domain name "abc.mobi" with domainit. abc.mobi is pointed to our mail server which is running at 188.8.131.52 (fake address).All mails that are being delivered to firstname.lastname@example.org have no problem getting delivered. We can also send emails out to other domains.I have recently configured BIND 9.3.6 on the same server (running CentOS) that is running our mail server. The purpose is to make sub domain dynamically without getting domainit involved. These subdomains will have incoming and outgoing emails as well. For example, I would want to make a usable subdomain "xyz" under abc and have email@example.com email address.
I have configured abc.mobi.hosts file as follows (/var/named/chroot/var/named/abc.mobi.hosts) $ttl 38400
creating independent sub-domains on my VPS.To describe this in clear words below is the example:I have a domain named as demo.com and k it as test1.demo.comand i have only one IP address assigned to me, which points to demo.com.So how can i set this sub-domain so that I will serve as a separate entity
I am completely new to Ubuntu so please make your answers really simple ! I want to set up a mail server for a home network and have been suggested I use the Ubuntu solutions. I am fairly proficient with Windows programs and even construct databases but I am a complete novice when it comes to command line instructions. Yes, I know I have been spoon fed!
I have been told that it is possible to install Server programs from the Desktop version and that they provide a GUI in most cases. Is that so? I have the desktop version running and up to date but I am unsure what to do next. Starting the Server ISO CD from Desktop seemed logical but when I did I was not sure if it was correct and backed out. I have also read a thread on this forum that suggests the use of Zimbra as a Mail Server, it sounded like my kind of solution so I think I would like to try that.
One last factor. I have an existing P2P network (2 Vista, 1 Mac Book and this Ub' desktop/server) running already which uses the Router for DNS. I suspect I am going to have to do things in a certain order if I am not going to go backwards and ruin the families email and surfing!
I've run into a strange issue with a DHCP/DDNS setup whereby when the DHCP server asks the DNS server to add a new host, the forward map is added correctly but the reverse map has the subdomain added twice (e.g. 192.168.25.192.168.25.250)I'm running ISC DHCPd version 3.0.1 and BIND version 9.2.3 on SuSE 9.2 - 32bit.Here is my dhcpd.conf file:
# dhcpd.conf authoritative; include "/etc/named.keys";
Got a Zimbra server FOSS edition running on CentOS5.5. Everything was running fine until couple of days just found out that web administration interface just does not give the proper status. Web console says that none of the services are running which infact is not true. Only service that is not running is logger. This is the zmcontrol status output
Just the logger service is not running all the others are. But web admin interface shows all are stopped. Also it can be seen that zmlogswatchctl is not running. Starting it manually does not do any good. It does not start and it dies out by itself.I tried to google and found a couple of bugs related to logger and web interface but those were old and should have been done in this version 6.
I want to setup either Zimbra, qmail or sendmail. i have no idea of these three mtas (i am new to these mail servers)but give me the suggestion that which one is better in case of security, fast routing the messages, scalibility and portability and cost.
