CentOS 5 Server :: Sending Logwatch To External Mail Address?

Nov 4, 2009

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, 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 " 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?

Software :: Logwatch Not Sending Emails - No Mail

Jun 8, 2010

I'm trying to get logwatch to email me. I think my logwatch.conf file is okay. I have postfix installed. The mailer as far as I can tell is set correctly ("usr/bin/mail"). When I run logwatch - I get "no mail for aubrey"

Heres my logwatch.conf file:
linux-qwkb:/home/aubrey # edit /usr/share/logwatch/default.conf/logwatch.conf
# This was written and is maintained by:

CentOS 5 :: Logwatch Not Sending Reports?

Aug 31, 2010

When I installed Cent before I got my logwatch messages sent to me. for somreason this new server I built I am not getting them. can mail off the server and there is no mail in the Q or in root. I also put in a .forward file in my root to mail to my external account and it works fine. I get mail from fail2ban and denyhosts but not the logwatch.Thoughts on what I could be missing? I check the link and the files are all there. I changed the config file to give me a High level of detail. Thats about it. If I use the command line for logwatch it sends mail fine. logwatch --detail high --logfile messages --mailto yourname@domain.com

CentOS 5 Server :: Sending All Internal Mail To The ISP's SMTP?

Mar 27, 2009

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?

CentOS 5 Server :: Postfix No Longer Sending Mail?

Jan 7, 2010

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


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.

Security :: Centos 5.5 / Rkhunter Result In Logwatch Mail

Apr 20, 2011

I have a server, running Centos 5.5. It runs daily rkhunter and logwatch. From both I get a daily mail.

I have a desktop computer, running Fedora 13 (almost 14...). It runs also a daily rkhunter and logwatch. But I get ONE mail from logwatch, which contains the result of rkhunter.

On the server, I want also only mail from logwatch, containing the rkhunter results. But so far, no luck.

How can I get the rkhunter results in the logwatch mail on my Centos server?

Ubuntu Servers :: Sending Mail To External Email (Outside LAN)

Apr 14, 2010

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.

General :: Logwatch Configure To Use SSH Tunnel Into Mail Server To Send Log Reports

Feb 28, 2011

We have following setup,

1. Webserver (Centos 5.5)
2. Mail server (Centos 5.5)

We have configured autossh successfully to create/manage the ssh tunnel into mail server in order to dump all emails to localhost port.

To auto start autossh in boot time we have included following into /etc/rc.d/rc.local,


So whenever our web application wants to send out emails it dump all emails to localhost:33465 port, easy piecy, all are working great

Now we have a requirement that logwatch reports should get delivered via the same ssh tunnel rather than installing postfix and configuring as a relay.

In logwatch is there a way to achieve that?

Networking :: CentOS Mail Setup - Sendmail Via External SMTP Server

Jul 30, 2011

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.

CentOS 5 :: Not Sending Some Mail Through Wordpress?

Dec 23, 2010

I am very new to CentOS and running a server in general. I managed to get a server setup with CentOS, and it's running a wordpress driven social networking site. Everything is fine except sometimes my server won't send registration/activation emails to some email addresses. This is a huge problem because people signup but then can't activate their account. I don't understand why its sending some and not sending others based on the email domain? The guys at wordpress said "it's that your server does not support SMTP or at least wp_mail() in its normal form" but that doesn't mean much to me.

Server :: Setup An MTA To Pass Mail Onto An External ISP/mail Provider?

Jul 1, 2009

I have a Fedora 10 machine that I want to setup to send email. However I don't want it to be a full blown SMTP setup.What I am looking to achieve is when something sends email from the local machine (e.g. from cron) to an address I want it to use an MTA on the local machine which will then connect to, and authenticate with, my e-mail providers SMTP server this will then take care of actually sending the e-mail.I don't want, or need, to setup a full blown SMTP service (i.e. only the local machine should be able to use it) so sendmail seems a bit over the top for my needs. Nor do I want to mess about with MX records (am I right in thinking this will mean I have to manage all mail for my domain?).

Server :: Postfix: Sending Mail From Multiple Domains?

Jul 20, 2009

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.)

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?

Server :: Sendmail Isn't Sending Mail For Some Reason And Keeping It In The Queue

May 14, 2011

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.
