Server :: Setting Up Email Address For Outgoing Mail
Dec 1, 2009
I have setup mail server on Ubuntu 9.10 and it's is working fine.I am using Webmin to addministrate my mail server.My Ubuntu server name abcs.I send a test mail from Wedmin for user gom.Why it keep adding InfoNet. What I would like is setup as email@example.com.
I just set up a new router for our home office. I've enabled traffic logging, and I'd like to have the logs emailed to me. However, in order to configure email-notification, the router needs and outgoing mail server. Forgive me, but I don't really understand the terminology being used here. I've googled this a bit, but I'm not sure I now what "outgoing" vs "incoming" mean in the context. I tried using my gmail account as the outgoing mail server (smpt.gmail.com) but it requires TTLS encryption, and there's no option for that on my router.
So I figured I'd setup a simple mail server on my local network. I have a dedicated server machine, so I'd just configure a mail server there. But I got stumped at the first input box (in the yast module):"Outgoing Mail Server".That's what I wanted to use this server for. What is this "outgoing mail server"? I understand it in a normal emai context (I think) but this is confusing me. I've read through the HowTo on the openSUSE wiki, but it still doesn't answer this question.Isn't there some way to have a simple, local mail server (without MX records and the like) so I can send email from a local machine?
I'm setting up a server and trying to make it *very* secure. Before I configured my web stack, I was about to install some security packages, Tiger and Samhain, but these packages wanted to install sendmail so that they can send outgoing notifications. From the reading I've been doing, I believe I want postfix instead of sendmail. It is my (perhaps mistaken) belief that installing postfix first will prevent them from installing this sendmail I do not want.
I want to install postfix with the following goals in mind:
* let PHP scripts send mail using the mail function.
* various system notification functions (cron, etc.) will be able to send their emails
* emails destined for root@localhost will be redirected to firstname.lastname@example.org
* let tiger and/or samhain send their notification emails
* NO INCOMING OR LOCAL MAIL IS PERMITTED. Because mail for my domain is handled by google apps, nobody will be checking mail on this server. Also, this server has very limited disk space. It is therefore very important that we don't have mail accumulating in boxes that will never be checked.
* no unnecessary ports, services, or cron jobs are running.
I've been reading a variety of pages that describe postfix setup on Ubuntu but these articles are imprecise, incomplete, and describe installation of things I don't want like POP/IMAP/etc.
There's also one final wrinkle. I will be setting up postfix to send via Amazon SES.
I would like to be able to have email sent directly to my computer at home (i.e. run some kind of mail server on it) instead of having to rely on Gmail, Yahoo or someone else. From what I've read it should be possible, but most of the guides out there seem to be oriented to enterprise-class setups, or at the very least a small business, and I think that a lot of that would be overkill for just getting my personal mail. The minimum *I think* is
- register a domain name, with the DNS pointing to my public IP (which is dynamic, so one question I have is whether I would have to use DynDNS or is DNS at any registrar going to be flexible enough to modify if/when my IP changes?)- something about MX records (I'm really unsure here, what exactly are these and where do I set them up? I don't think a free DynDNS account lets one handle this, does someone know which of their account types supports setting this up?)
- Install sendmail and postfix (which seems like a PITA, but much documentation appears to be available)
I just discovered View > "All message headers" in the Evolution email client and am quite concerned that all my out going emails contain my personal IP Address. I know that this is standard email protocol but i'm wondering if it is possible to hide or modify this header information? Or would i be better off using a webmail client?
I have a small home network running mail agents Evolution and Thunderbird, and connected to the internet via Comcast. Originally I used my campus office computer as a mail server, but encountered problmes because Comcast started blocking port 25, allegedly because of span problems. I need to change the setup on my campus office computer so it uses port 587 when functioning as an outgoing mail server.
Can anyone recommend a tutorial which tells me everything to do in order to accomplish that?
At present I'm, using Comcast's outgoing mail server, but I started having problems with sporadic blokage of outgoing mail with attachments, which Comast can't explain.
How do I check/setup that only the server can send mail (maybe by IP or hostname)? I have a debian server that sends mail through the PHP mail() function with no problems. The server uses sendmail. My concern is how do I make sure only the server itself can send mails through that server. Because it would be bad if spammers would use it as a relay server.
How could we bcc all outgoing / incoming email through my Sendmail (8.14) Server? I tried this /etc/procmailrc :0c ! email@example.com But this get looped and backupmail received multiple emails of each for domain.com while sending locally from one user to another user.
i have a linux box at work that was configed by some that has left the company. we have an email add: e.g firstname.lastname@example.org, if you enter that mail add to a new email it then sends the mail to several email accounts the are on the server.i would like to remove and add new users onto that email address, is there anyone out there that can help?
I have a postfix system that sends allot of emails to customers and web site visitors. A lot of visitors just enter an invalid email in the WEB form just to download some files or do other tasks. Is it possible to BLACKLIST specific email addresses so the system does not send to those addresses? I can grep from the postfix mail log all those fake emails and place them somewhere.
Is there a way of allowing only certain domain to send e-mails to certain specific e-mail address. I am using Sendmail, and I have an alias which translate to certain members of staff within my organization. I don't expect e-mails from outside our domain to be sent to this alias e-mail address.
i have ip's which are 188.8.131.52 and 184.108.40.206. If i log into 220.127.116.11 the outgoing ip shows up as 18.104.22.168 and if i log into 22.214.171.124 the outgoing ip still shows up as 126.96.36.199. I need to set it so that when i log into a 188.8.131.52 to shows up as 184.108.40.206 as the outgoing. Same for when i log into 220.127.116.11 it shows up as 18.104.22.168 on the outgoing end. I need to know how to set it like this. Anyhelp would be greatly appreciated. I am using my VPS as an SSH tunneling. I would to have it set up so that if i log into 1 account the ip will be x.xx.xx.1 and if i log into another account it would be x.x.xx.2 ect. I have been searching for hrs on thsi stuff and no luck at all.
I am trying to figure out how if it is even possible to set up my centos server to email messages to gmail account I have tried mail -S Test email@example.com but every time it say in my log files that Connection refused by [127.0.0.1]
Im 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
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.
As a part of migration I am proposing different scenarios to my organization. One which is asked to prepare is to configure multiple mail servers to handle incoming and outgoing mails. Say I have -[URL], I need to have accept mails from [URL] and send mail from [URL].
We run a service in which a customer types in a form and gets a confirmation email after submitting the form. We are on a server with no control panel. We are running CentOS 5.
When we did our testing sendmail sent mails just fine and I was able to receive them. After we went live we found that 75% of our emails are being rejected by other mail servers. Doing research is seems that the headers indicate the emails are coming from 127.0.0.1.
We need to correct this problem, as well as do everything we can to reduce the risk of our mails being marked as spam. We do not receive mail on this server, but rather send mail. We have another email server on another server for receiving mail for our domain, which is already configured with cPanel (which doesn't have a problem).
We can not use cPanel on this server because of certain security restrictions.
I know that sendmail is cryptic to configure. We are willing to switch to Exim if necessary.
As far as installing Exim, I understand it's as easy as:
One of our client having issue with the qmail. The issue is if any one send email to firstname.lastname@example.org (email@example.com the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.
Is there a way to control all email address in one server manage all email application software either win OS / MAC OS or Linux Distro. I have experience about email when the pc crashed i dont have any backup for their email data also email address.
I have users [URL] unable to send email to [URL]. [URL] user also unable to send email to [URL]. But both email addresses are fine as they can receive email from others or from [URL] and [URL]. I able to telnet mail server 110 and 25, no problem. Version: ESMTP Sendmail 8.12.10
Feb 23 11:36:35 mail sendmail: o1N3aZxt016215: to=<firstname.lastname@example.org>, ctladdr=<email@example.com> (501/501), delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=442918, relay=gas.com, dsn=5.1.2, stat=Host unknown (Name server: gas.com: no data known)
I've come across a strange issue where any email address that I email with mail returns an error "Bad Address"
Fairly new Centos 5.4 Install, sendmail is the MTA. Linux 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux DNS is working fine so there isn't a problem. [root@hn1 /]# host -t mx iol.co.za iol.co.za mail is handled by 10 mg1.iol.co.za. iol.co.za mail is handled by 10 mg2.iol.co.za. iol.co.za mail is handled by 30 vulpix.iol.co.za.
Yet when I try to use mail it fails: [root@hn1 /]# which mail /bin/mail [root@hn1 /]# ls -lrth /bin/mail -rwxr-xr-x 1 root mail 83K Jan 7 2007 /bin/mail [root@hn1 /]# mail -s "test" firstname.lastname@example.org Bad address Nothing in the maillog.
