Is there anyway I can disable sendmail on my various machines and configure mailx on them to utilize my Postfix SMTP server? Thanks, Dan

I setup a kickstart file that contains only @core and several packages explicitely listed. postfix is listed, sendmail is not. And there's no package where I would think it needs cups. Nevertheless, after the install I now have postfix *and* sendmail on the machine and sendmail even being enabled. And cups is installed. How can I find out what forced them (and probably many other unwanted

I'm attempting to configure sendmail to relay outgoing mail to an internal smtp server. I found that the commented line in sendfile.mc that starts with 'dnl define(`SMART_HOST'... needed to be uncommented and a valid value inserted. No problem there, but when I attempt to 'make -C /etc/mail', I get WARNING: 'sendmail.mc' is modified. Please install package

hey friends, I have installed sendmail or it would rather say it comes default with the centos. I am using Centos4.0 and I am trying to configure sendmail with virtual users.

The problem I am facing is that if the user1 at example1.com sends the mail to the user2 at

My guys, My firewall seems to block an attack my Centos / Sendmail boxes on port 110. These servers require a reboot after each attack. My firewall says it's blocked? Do I need to patch something on sendmail? Or is my firewall not doing its job (Sonicwall)? This is not the first time this has happened. 11/20/2008 02:53:04.864 - SYN flood attack dropped - 75.2.205.141, 48102 -

Hi Folks, I have a couple of questions which I hope that you will be able to assist with, first some background.

I have a CentOS 5 machine at home, behind a NAT gateway. Among other things, I'm running mdadm in monitor mode to alert me to RAID failures. I want it to send messages to my main email address. Any messages I send from the home CentOS box to that email address are being rejected with this error: Deferred: 451 Could not complete sender verify callout My understanding is that the

I had the same question, and I want to make sure I'm clear..... This implies to me that Asterisk itself doesn't use SMTP, but rather dumps a message into some directory that Sendmail on the same box will see and process? I have no problem getting Sendmail to use a smarthost, but am I understanding the Asterisk part of this properly, or is there a way to get Asterisk to DIRECTLY use a

I have a stock CentOS 5 system as far as email (sendmail) is concerned that is on our corporate LAN. I am not trying to set up a mail server; I merely want our CentOS systems to be able to send out emails. This works as long as the recipient's domain is our local domain. Any email send to recipients that are not in our local domain get stuck in the queue: # mailq

I'm a bit baffled by this problem. Maybe there's a sendmail guru out there who can help me out here. We have some end-users who need to receive system-generated mail that originates from a java-based application on our network. The java app sends the mail through our sendmail cluster, which then sends the email on to the end-user over the Internet. The size of the emails can range from

Is there an easy way to configure sendmail to only send mail to addresses in one particular domain?

Hi All, I have a strange problem that I don't understand.

CentOS 4.6 Hi All: Is it possible to force sendmail to use a specified host name for outbound email to a selected domain name instead of the host name that can be found by looking up the DNS entry? The problem is that we have a client that uses the same ISP as we do and the IP addresses assigned to both of us are very close. This has resulted in connection problems specifically with our

We have an issue with some customers who refuse to accept ICMP traffic to their mail servers. It seems that they have put Mordac, preventer of information services in charge of their firewall policy (http://en.wikipedia.org/wiki/List_of_minor_characters_in_Dilbert#Mordac). My mail logs are showing that customers who specifically disallow ICMP traffic have many "Connection Reset"
