I have changed over to AT&T U-verse. I need help getting my sendmail able to send out.
From AT&T website
Incoming mail port number: 995
(make sure secure connection (SSL) is checked)
Outgoing mail port number: 465
(make sure secure connection (SSL) is checked)
how to setup sendmail to use SSL , userid,password and port 465 ?
I have configured dovecot to use separate user and password file. Can I tell endmail to use it too? If not, then does postfix can this?

what should I add/change to set up port forwarding of port 1000 to ip 192.168.1.200. also how to get the answer sent by 192.168.1.200 follow the same route used by the data received through port forwarding.
Does anyone know the black art of configuring sendmail for proper authentication and SSL on submission port (587) ?

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.
In my "computer room" I have an ATT U-Verse TV decoder box and my computer connected to a Netgear Switch. The third port on the switch connects to the ATT router. I've just noticed that when I power on the U-Verse TV box I start getting a lot (200-250 KiB/s) of received packets on my Debian Lenny machine as shown in the System Monitor app. I don't show any outgoing traffic in response. That explains why the lights on the switch are blinking at the same rate for both devices. So, what, if anything, is this telling me? Is this normal, or is the ATT router spamming my Linux machine for some reason? Is this a potential problem?
Added: Or is this just telling me that the NetGear FS-105 is not actually an ethernet switch?
I wish to setup an email server, using sendmail and DOVECOT on F13 With no modification of the DOVECOT config file ( fresh installation ), I can see that :
service dovecot restart

and of course, I cannot connect as pop3

View 5 Replies View RelatedHow do I setup Self Port Forwarding on Fedora 13 x64 How Port Forwarding Works Port forwarding allows access to a local area network by a remote user through forwarding ports that provide ftp access and web server access. The operating systems use a kernel or ipfirewall to carry out the port forwarding process.
There are several different ways that port forwarding is accomplished. * Self Forwarding: Self forwarding is port forwarding that is accomplished on a local area network that has multiple computers connected to the network. Since all of the computers share the same IP address, the port forwarding must be conducted within each computer on its own system. If the local area network router has a network access translator then the computers that are connected to the router must also do port forwarding within their own system.Port forwarding can be accomplished with Unix systems however the port can only be accessed by the root administrator. This is a less common method of port forwarding due to the fact that using a root administrator poses risks to the system because the users will often take a detour to a higher port number to gain faster access to the server.Double port forwarding involves the use of multiple routers that join computers on a local area network. As a result, the ports on one router are forwarded to another router that acts as a gateway. The gateway router then forwards to a host on the local area network (LAN). This type of port forwarding involves the communication of several components which include the session server, session client, and session port. When the user establishes a connection the session server will connect to one of the session ports that are to be forwarded which will in turn, forward the port to the session client. Reverse port forwarding is used when access is required to a port that is protected behind a firewall.
While port forwarding is convenient, there are a few things to be aware of when using this type of technology. If you use port forwarding only one port can be used at a time and the machine that is receiving the port forwarding can only view the information as coming from the router instead of the original machine. Additionally, port forwarding can open up network access to other machines that may be able to find the port forwarding by gaining unauthorized access. I know how to setup port forwarding in my router along with Dyndns.org free ED, but my local area network has multiple computers connected to the network on my router. All of the computers share the same external (public) dynamic IP address; when I setup port forwarding only my Web Server can access the internet, so how do I setup Self Port Forwarding on Fedora 13 x64

possible to run Qmail and Sendmail on one server, both on another port? I need qmail for Plesk and sendmail for OpenEMM Now qmail is working for plesk, but if I install qmail ( I tried install it also from source) and try to run sendmail, I still get this error: Starting sendmails: listener sendmail: illegal option -- q chich probably means, that there isnt full sendmail version.

1. TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')
2. Define define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
3. DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
My problem is that when i try to open port 25 with telenet it takes lot of time like more than 1 minute to open session and another 30 - 40 seconds to respond to "ehlo" command.
Also when i try to open telnet session on port 25 in another server it hardly takes 1-2 seconds open session.
I have been trying all day today to setup a sendmail SMTP server on our Red Hat 5.5 dev box. We have 2 network cards, 1 to the local network with a 192.168 prefix and an external card which goes out to the web through a BT leased line through a Cisco router.
First I followed one of the many helpful tutorials online to setup sendmail, installed all the required packages and made a couple of small config changes to allow the service to listen on all IP addresses rather than just the localhost 127.0.0.1.
The main change is in the /etc/mail/sendmail.mc file where I have changed the following line;
DAEMON_OPTIONS(`Port=smtp,Addr=x.x.x.x, Name=MTA')dnl
I have tried removing Addr completely, setting to either the local or external IP and then rebuilding the sendmail file using 'make -C /etc/mail' and then restarting using 'service sendmail restart'
The SMTP port has been added into the firewall and it is showing to be listening on IP 0.0.0.0:25 which I believe means it is listening on all IP's assigned to the machine, sendmail is also in listen mode and running correctly.
Finally I have changed the /etc/mail/access file to include the local IP range 192.168 and external IP range and rebuilt this into the /etc/mail/access.db file and then restarted sendmail.
Googling the error all the sites I have found talk about making sure the 'DAEMON_OPTIONS(`Port=smtp,Addr=x.x.x.x, Name=MTA')dnl' line is uncommented and not much else in terms of what else might be incorrect.
I am starting to run out of ideas on things to change or check, telnet works correctly on other ports on the same server, ie httpd for apache on port 80. I have also rebooted the server to make sure that it wasn't something odd happening.
I'm writing a script that will send an alert email given certain conditions. I have the impression that sendmail is what I need to do that. I just don't know how to use sendmail at all. I assume I have to set it up like a typical mail client so that it has a mail server to log into to send from.
I've looked through the man pages, but I can't find anything in plain English there on how to set it up, or how to use it once it is set up.
I am trying to su from liveuser to root to run yum update. If I am not root, I get a message that says "need to be root to perform this command". I am logged in as liveuser. If I do an su root then it says that my password is invalid. Since I did not set up the root user, I do not know the password.

I have no experience with this and would like to know if anyone thinks there are issues that I should be aware of before going down this path.
Also, I have not been able to find any good, STEP BY STEP, documentation on how to set up DKIM with Sendmail.
I am also not sure if you need a certain network configuration for DKIM to work...this is what I am working with:
My webserver (centos 5.3, sendmail 8.13.8) sends outgoing mail and has a valid reverse DNS that matches a forward DNS. The MX records for my webserver's domain point to a third party email provider who handles the incoming mail for that domain. I added an spf record that signifies it that my webserver is authorized to send mail for mydomain.
