By default, CentOS 7 will use postfix as MTA. That was an excellent decision I welcomed the day RedHat made it. Beginning with my firat RedHat (it was somewhere around RedHat 5 IIRC) I always have been replacing venerable

What makes Postfix superior in fighting spam? How do I integrate MIMEDefang, SpamAssassin, and ClamAV with Postfix? Are there migration guides for moving one's Sendmail anti-spam and AV

Hello Everyone, We are using CentOS 5 system for certain application. Those are VM guests running in VMware. There is datastore issue occasionally, causing all file systems becoming read only file systems. So application stop working, and opened files cannot be written either. We cannot even ssh login to the system. Typically we had to power cycle the VM. We are trying to add reliability to the

Hello All, I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I?m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you, Xinhuan Zheng

I am using Asterisk to send Voicemail out as Email. I am running into a problem I believe to be caused by the exchange server requiring SMTP authentication. I cannot get the sys admin's to turn it off. Does anyone know enough about sendmail to help me. I am assuming that the default mail client is sendmail. It will also send to other non-SMTP authenticated servers. Your help is much

Hi, I am recovering a CentOS 5.4 system. I've copied all partitions into the recovery system. I've installed grub boot loader. However, the original system is using /dev/sdb1 for root (/), while the recovery system is using LVM (/dev/vg0/lv1) for root (/). When recovery system boots, I got the panic error: * Mounting /dev/sdb1 on /sysroot * Mount: mounting

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with,

I have a problem getting spamd and sendmail (both stock CentOS4 rpms) to work together on a couple of smtp relay machines. This is clearly a configuration issue and no doubt revolves around my lack of comprehension of how this is to work. Basically, the setup consists of two frontend public smtp transports that redirect all email through a firewall to an internal imap server for final

Dear CentOS Community Is totally clear there's no support sendmail platform today, but I need to stop SMTP brute-force attack on sendmail. My server is attacked today, my maillog look like : 4624 at myserver.com>, proto=ESMTP, daemon=MTA, relay=myserver.com [127.0.0.1] Jun 14 19:07:01 at6412 sendmail[24627]: q5EN71jC024627: from=<>, size=3958, class=0, nrcpts=1,

Running CentOS 4.2 with all updates. I've been using sendmail for my MTA since forever. I've grown used to it and I can make it do what I want it to. However (there's always a catch, isn't there)... Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to

What's the reason for the burst of sendmail complaints below? My CentOS 4.3 server only handles internal mail for my small network. It doesn't handle Internet mail at all, so I guess I can't blame a crack attempt for this. IPTables rules should prevent external connections to everything except SSH's port 22. I've looked through the other logs hoping that some other activity

Guys, I've had a weird problem with Sendmail misbehaving in a way I don't really understand. I've worked round the problem but I'd like to understand what was going on. The MX for one of our domains, blah.com, pointed at an internal Exchange server. Mail relayed to a Sendmail MailScanner which then delivered to Exchange for this domain. The domain expired leading to all its mail

Hello CentOS list, I have a requirement that I need to use encryption technology to encrypt very large tar file on a daily basis. The tar file is over 250G size and those are data backup. Every night the server generated a 250G data backup and it?s tar?ed into one tarball file. I want to encrypt this big tarball file. So far I have tried two technologies with no success. 1) generating RSA 2048

Ok, so a bit of a long subject line there... I'm running an email server using postfix, but a critical third-party package being used requires 'sendmail' the package.? No, I can't uninstall that package, please don't suggest that, and I don't have control of its requires.? So both postfix and sendmail are installed, and that's just the way it has to be.?

I know this is a "generic" question, but fully CentOS related. I attempted to set up i386 v.4.1 on my primary computer at the co-located site, and thought I had everything squared away till I discovered the machine was refusing mail connections. AFIK, I had no firewall or other objects blocking port 25. It has been my experience that with most arch's and versions where sendmail is

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably

I have two CentOS-6.4 servers, in different places. I am running postfix/amavis on one, and sendmail/procmail on the other. I don't recall having any difficulty setting up sendmail many years ago using sendmail.mc . But I found postfix very complicated to setup last year. (It's working fine now.) I recall that when I asked for advice one person advised me to read 2 books on postfix, and

hi all, running centos 4.7 i686. I seem to have an o pen r elay sendmail server. How do I close it? I have the STRAIGHT centos install sendmail.mc file. Only thing I changed was: dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl so as to allow incoming email and not just localhost. however this seems to relay everyone. I looked at http://www.sendmail.org/tips/relaying but it

I have almost zero experience with sendmail. I'd be willing to pay someone to set this up for me, interested? KNow of someone?
