similar to: help with sendmail closing relay

HI folks, I've an up-to-date CentOS 5.x box on a small intranet (<20 users). We did a reboot over the weekend and all appears well except that clients on the LAN can no longer send email. Just hangs/times out. No clear identifiers in the /var/log/maillog or /var/log/messages. We're not setup for ESMTP as it's a closed network and I'm really hoping for a kickstart as to

Hello everyone, I tried to configure sendmail so that I can use mail() in php. I don't host my email server, my ISP does. I just want to configure sendmail so that it uses external email server (my ISP) to send mail. When I executed mail(), i got no error report from php. I checked /var/log/maillog and it indicated that the message was accepted for delivery. However, it didn't

The mail server is running fine since 5 years and is based on :- sendmail- dovecot- roundcube It serves 2 differents domains. I've recently installed pigeonhole for fc17, and managed to configure managesieve plugin in roundcube

All; I installed sendmail via yum, but if I test it like this: echo "Subject: sendmail test" | sendmail sbob at quadratum-braccas.com I get a local mail on the server with this every time: Message? 1: From MAILER-DAEMON at kdb-bugs.example.com?

Gents, I have added the following to /etc/mail/sendmail.mc and rebuilt it trying to control spam. I still get about 25 spam messages a day. Is there something else that can help control spam?

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 - OK not really an Asterisk question but it is affecting one of my favorite features - emailing voice mail! I've posted on some Linux forums and sendmail.org but no response so I'm hoping someone will take pity on me ;-) My ISP requires SMTP authorization and I'm having a heck of a time getting it to work. I've included the following below: Asterisk 1.4.21 CentOS 5 Sendmail

Hi all, I've been trying to hit on the right configuration combo to allow relaying from specific users and/or domains to an internal box running Sendmail. Reading the docs at http://www.sendmail.org/m4/anti_spam.html#relay and http://www.sendmail.org/m4/anti_spam.html#access_db_fine I would appear that I should be able to all per-address relaying in /etc/mail/access by enabling

I'm new to dovecot and sendmail and my server doesn't forward mails to 'dovecot deliver' at all. I was reading http://wiki.dovecot.org/LDA/Sendmail and this http://www.dovecot.org/list/dovecot/2009-June/040353.html from the mailling list but I could figure it out myself. I someone could point me into the right direction. I'm confused with the config for LDA. Basically what I

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

Apologies for resending this, I am not sure it made it through the first time.. --- Included below are my config files: sendmail.mc, dovecot.m4, dovecot.conf, dovecot-sql.conf.

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

hi, i have installed sendmail+mailscanner+clamav+spamassassin and work fine, but my telnet localhost 25 is not authenticates. i read a lot of docs but something i don't do it. i have installed centos 4.3 with: sendmail-8.13.1-3 sendmail-cf-8.13.1-3 dovecot-0.99.11-2 mailscanner-4.50.15-3.9 clamav-0.88.4-1.9 spamassassin-3.0.6-1 cyrus-sasl-2.1.19-5 cyrus-sasl-plain-2.1.19-5

Hi I need to set some of our boxes to send mail through our smarthost. In the sendmail.mc file i have set the smarthost and rebuilt the sendmail.cf file. When i send a mail locally on the box though i get this error Diagnostic-Code: SMTP; 553 5.1.8 <root at localhost.localdomain>... Domain of sender address root at localhost.localdomain does not exist What else do i need to edit as

By default, sendmail only listens on the localloop: DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl But by default to allow sendmail to even work the iptables entry is: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT Without this, sendmail can't even connect to localloop. But should I handedit this line to something like: -A

Recently, I added the below line to my sendmail.mc and rebuilt. Everything was working just fine until sometime today. In looking over the maillog, it seems if almost every piece of mail was rejected because of this configuration - mail that I know is OK, valid, and not a source of spam, like tamu.edu. Not only that, but the mailing list from centos was being rejected as well. Anyone know
