Hi, all I want voicemails to be delivered to recepients by e-mail. I have set up voicenail, and I can see asterisk is using sendmail to send messages out. Using Ethereal, I can see that messages are leaving my network, but receipeint mail server never replies back. As a result, mail delivery is timed out. I got a book on sendmail and it looks quite complex. It will take quite a bit of time

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

Greetings, I'm refining a CentOs configuration installation, now just over one month old running on a colocated production server. Previously, we ran a version of Fedora for over seven years. Specifically, I'm reviewing our sendmail configuration, both with respect to authentication and port usage. Previously, we had the following line in the sendmail.mc line:

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

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, 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'm probably missing something obvious, but I can get sendmail to give me AUTH PLAIN and LOGIN options. What I have is fairly standard configuration. The relevant part of sendmail.mc looks something like this: define(`confCACERT_PATH',`/etc/ssl/certs') define(`confCACERT',`/etc/ssl/ca-bundle.crt') define(`confSERVER_CERT',`/etc/ssl/smtp.crt')

Hello. I am scratching my head about sendmail for a simple thing: I have a CentOS 4 box on which I would like to receive e-mails. when I type 'telnet localhost 25' I can connect successfully to the sendmail service. Now if I type: 'telnet 192.168.0.30 25' on the same host the connection is refused. It also refuses connections from another host. I have edited the

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

Dear List, I recently spent some time out of the USA, and found myself in a hotel that blocked port 25 which prevented my laptop's ability to connect to my office mail server. I did a scan on the internet and made the observation that this was a common problem. I had port 22 available so I was able to get my office server set up to accept mail on 25 and 587 without difficulty. The command

Hi. Apologies to the list for sending this twice as I forgot to enter a proper subject line, I wanted to write the content first and then make up the subject line ;-) -------------------------------------------------------------------- I am trying to configure sendmail that is looks up the users credentials to allow them to send email via that server via an imap server on the same machine

I have a user who has Mac OS 10.4.8 with Entourage X. The email server is sendmail 8.13.8 and is setup to use STARTTLS on a CentOS 4.4 system. It appears from everything I have googled that only Entourage 2004 will properly function with STARTTLS. Has anybody any experience with Entourage X ... specifically is there something I am missing regarding the CentOS server setup or are all Entourage

Hello, I'm trying to set up a sendmail server on 4.8 that supports auth-based relaying. I followed the procedures at http://puresimplicity.net/~hemi/freebsd/sendmail.html, and aside from having to run makes manually in the library directories, I had no difficulty. I did not use the rebuild world recommendation, though. Everything is up and running, but whenever I try to send mail
