CentOS 5 Server :: Send Mail From A Different Domain
Feb 12, 2009
I have a CentOS 5.2 server with hostname support.companyname.local It's used to run Request Tracker 3.8.1. I need to be able to send email from this machine and make it look like the email came from user@companyname.com instead of user@support.companyname.local
There is an requirement, intranet people they may not have internet access but they want to send mail to external domain(internet),but in that intranet network one machine can have internet access. Is there any solution for this requirement.
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. xxx@yyy.com... Connecting to [127.0.0.1] via relay... 220 my.server.com ESMTP >>> EHLO my.server.com 250-my.server.com ..... Closing connection to [127.0.0.1] >>> QUIT
Performing the same test and sending an email to a non-hosted domain works fine.
i'm trying to send a mail with "mail" on my cent os console , but without success. In Suse it's quite simple with "mail": mail -r sendersaddress@domain -s "subject" targetaddress@domain </tmp/filewithcontent
My server already installed and works well, but I can't send or receive mail with Squirrelmail, the error that appears is: Server replied: 67 Can not execute command '/ usr / sbin / sendmail-t-i-fteste@gabinetedeengenharia.com '.
i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.
For example, if i send one mail from user1@mydomain.com to user2@mydomain.com the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to user1@mydomain.com or user2@mydomain.com (for example), so please tell me what do i do to get the mail.
I recently purchased a domain and I have setup what I believe are correct dns records from the domain companies control panel. I have the domain pointing to my server and that's working fine. I also have an MX record for my domain. Now, I can send emails from my email account just fine however I cannot receive any emails coming in to my account. Heres an example:
[dalton@int-interactive mail]$ echo "hello world" | sendmail -v dalton@int-interactive.com dalton@int-interactive.com... Connecting to [127.0.0.1] via relay... 220 int-interactive.com ESMTP Sendmail 8.13.8/8.13.8; Sun, 21 Aug 2011 14:45:16 -0400
I recently install CentOS 5.5 on my small server. Unfortunately, I have problems with my mail configuration. I don't know anything about sendmail and dns configuration so I am just looking for something easy to set up. I use cron to perform automatic task. I set up the variable $MAILTO in cron to my regular mail. Cron send the mail but it is stuck in the queue.
I have one major problem in my mail server. I am not able to send mail to other domain yahoo and rediff. and my ipaddress is blacklisted. So Finally I checked logs. Mail queue is high. Log shows spam and junk mail created in my mail server. he following are the logs. Iam using qmail server. One more thing is in link is there when I click that link its go sex websites. I will try all mail queue logs. It shows the same website redirection. So I don't know its happen. My thought is spam create from that website.
I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being user@mydomain.biz it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name. The Debian default
I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.
I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.
I'm having a problem with my mail. When I send mail, it takes a long time for the send to complete.In the below, datestamp is just a simple script to put in a no-white-space date/time stamp.
Code: $ datestamp ; mail woodnt; datestamp 02-05-10@193844
I have set up postfix and dovecot as per the Ubuntu anual and appear to have a functioning mail server.Using the sendmail command I can send mail and I receive mail in ~/Maildir. Using Thunderbird I can read any mails received but I can't send any mail from Thunderbird. I have tried with both STARTTLS and SSL/TLS and whilst I get the prompt for a password I keep getting the message my password for my server is wrong.I have ports 25, 465, 587 and 993. Is that all the right ports?When I ping my domain name it resolves to my router name whereas I believe it should resolve to my IP. Could there be a problem with my host file? I've had a play but to no avail.Here's the error in mail.log.
I'm running SUSE linux Server version 11. I want to configure mail server with postfix & cyrus-imap. For that, i have read many documents in Internet by i met issues. I'm running DNS in this server & it's ok Now I cannont send mail through command line.
i have an server which have my site on it, server have an public ip and site works fine..the thing that i done to enable mail server is :
1.select sendmail option as mail server(in joomla). 2.install and configure sendmail in server (which ubuntu installed on it )
**if i use my website locally mail server works fine i can send message and receive , but when i use web site from Internet mail server seems not working at all
i basically had this system installed for our mail system.The setup is as follows:
1. Operating system installed is Debian ver. 5.0.3
2. Roundcube is installed as a webmail(if its right for me to say that)
3. The server is hosted right here at our offices
4.The server uses relay system to send mail i.e. relays all our mails to our ISP
That all i can say about the configurations becuase thats as much as i understand it.The problem now is that we are not able to send or recieve emails from both internal and external.I tried to send mail to a collegue in the office who is on our local LAN,Roundcube says sent successfully but the person does not recieve the mail.i tried to send to my yahoo address but nothing.I dont know where these mails have been trapped.
I have a bit of problem setting up sendmail on my server. I've gotten so far that I can send mail from my mail server and relay mail from my LAN computers through it. Also, local delivery seems to be working.The problem is receiving mail from other domains. When I send mail from my gmail account to any user in my domain the mail gets delivered back to gmail as it exceeds the max hop count.The mail gets bounced between my ISP mailserver which I use as smart host and between my server.The problem seems to be that my mail server won't accept any mail it is supposed to receive.
My question is: 1] i am able to send mails to localhost or any user of localhost..through any user... 2] able to send mails to extrnal domains like gmail yahoo rediff etc..
I am unable to send mail in internal domain..detail..Main mail server is exchange i configured 1 sendmail and another machine for nagios this both machine are not sending mails to me or on my domain mail id..
I had qmail installed using squirrelmail as the webmail. At first I can send email to any destination. After I have changed the domain, I am getting this error: ERROR: Message not sent. Server replied: Requested action aborted: error in processing. 451 Temporary local problem - please try later.
I'm trying to setup notification function for the Nagios Core which use Mail to send notification.I got an account from Rogers. I have SMTP server, email account with authentication information.My Nagios server is in a workgroup, there is now domain assigned to it, I just use nagiosserver.localdomain in /etc/hosts.I added Rogers SMTP server in /etc/mail/sendmail.mc and Future (AuthInfo) I created an /etc/mail/AuthInfo and add AuthoInfo:smtpserver "U:user" " P: pwd" "M:Plain"I added smtp server in /etc/mail/access for RelayI added root@nagiosserver.localdomain on /etc/mail/virtusertableI regenerated sendmail.cf by user m4 commandrestart sendmail service.When I ran: Mial -s test nagios4ccs@rogers.comIt did not prompt any error message , in the maillog it says the message is queued but It can not be sent out
My test messages from one mail server to another are getting sent to my spambucket and the only error in the logs is: warning: numeric domain name in resource data of MX record for [URL]: 74.63.64.42
I have a Slackware 12.1 box with mail server running on Postfix and Dovecot. My domain name is,say, [URL].. I have another domain, mail.xyz.net. I want to use both the domain for incoming. Like, someone sends mail to [URL]... otherone sends mail to user@xyz.net. Both the mail should be received.
