CentOS 5 :: Set Mailx To Use External Smtp Server?
Jan 14, 2011
In Red hat i used the nail command to send mail using an external smtp server without sendmail or other mail services active. My question is: In Centos 5 nail is not present but is present mailx in version 8.1.1-44.2.2
Is there a way to set mailx to use external smtp server ? because in many forum i get the string mailx -S smtp= etc.etc. but in my case the -S parameter generate mailx: invalid option -- S antoher question is there a an official repository to download rpm nail for centos ?

I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.

In order to have greater control over the emails sent out the company I imagined the following scenario.ScenarioDescribing in words what I need.ser sends an email to user@hotmail.com for example, using the smtp of my isp (is the internet).Before the email is sent, the firewall checks if the recipient is blocked transparent, if you are locked out rejects the email.I searched several forums and mailing lists, but did not find scenarios similar to mine.Where found situations in which the mail servers were internally in the company, which is not my case.

I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.
How do I tell php to send an email with mail() using an external mail server?
The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.
I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.
I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?

I'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :
Code:
relayhost = [myMailServer.localhost]
smtp_sasl_auth_enable = no
smtp_use_tls = no
disable_dns_lookups=yes
smtp_never_send_ehlo = yes
code....
I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.

I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.
After that I ran the same command with the verbose option:
/usr/sbin/sendmail -v root <prueba.txt
And this is the output:
root... Connecting to [127.0.0.1] via relay...
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600
>>> EHLO localhost.localdomain
250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you
250-ENHANCEDSTATUSCODES
[code]....
For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?

I have a dedicated server running CentOS 5, Plesk 9.2.2, SMTP Postfix and Courier-IMAP.The issue I have is that on all domains on the server receiving email works fine however sending email never seems to work. This is from email programs, my phone, webmail and PHP. None of them seem to be able to send email. If it is of worth Spam Assassin is running however I don't feel it is causing any problems.

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?

I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
test problem:
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).

I've tried googling this, and am having trouble finding something that doesn't end up being dizzying or confusing.
I was wondering if anybody could provide me with a concise, conclusive answer/guide.
I have a set of servers which require redundant SMTP relay. The first two of their SMTP relays are their own SMTP servers, and as such, are not dependable in the event that their network/servers go down. Their monitoring software runs on their machines as well, and uses the SMTP servers they themselves host.
I need to set up an external SMTP relay box that they can use to relay their monitoring alerts/admin notices in the case that their mailservers go down.
I have a company exchange server with pop/imap support @ my disposal but, unfortunately, that box runs Windows and does not permit any changes to services or additional software to add for the purposes of relaying clients.
So now, I need to create a dedicated linux box that can act as a relay to send email coming from the monitoring/admin/alert software in case their first two smtp servers have gone down.

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

I am trying to run though the qmailrocks setup on a centos 5.5 and I am running into an issue when trying to telnet to port 25:
telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
Everything else seems to be working (telnet to 110), and I turned off the firewall entirely, but I still cannot telnet to port 25. I also get a blank error within squirrelmail when attempting to send mail out (ERROR:Message not sent. Server replied: ). I apologize for not going directly to the qmailrocks forum, but they are currently closed down (due to lack of funds). I also am a newbie, so I apologize for the lack of needed information. If anyone has any ideas, please let me know what information you would need.

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.

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 myacount@mydomain.com as the email address for root.
But it doesn't work for logwatch because it sends as from root@localhost.localdomain, 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:<root@localhost.localdomain> 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 [1] section "24.3.1.4. Masquerading", but it doesn't work. It seems that masquerading in sendmail is broken or something is wrong in the documentation.
[1] [URL]
I have sendmail 8.13.8-2 and centos-release-5-4.el5.centos.1.
Is there a way to specify the "From:myacount@mydomain.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 am running CentOS 5.5 and am trying to get Nagios to send out Emails.
After a bit of reading I have the following in my /etc/mail.rc file:
Code:
[root@linux ~]# cat /etc/mail.rc
set ask askcc append dot save crt
ignore Received Message-Id Resent-Message-Id Status Mail-From Return-Path Via
set smtp=172.29.1.76
You have new mail in /var/spool/mail/root
[root@linux ~]#
I have Nagios setup correctly and introduced an error to generate an Email but nothing has come through.I suppose I have two questions:
1. Is mail.rc setup correctly?
2. Can I test to see if mail.rc is working correctly?
