General :: Setting Up SMTP Authentication In Sendmail
Dec 22, 2010I need to send authenticated mails from a RHEL machine to a relay that only accepts authentication mails from domain users. I've never done this so I'm a bit lost. I read some sendmail docs and I uncommented these optins in sendmail.mc file
define(`confAUTH_OPTIONS', `A p')dnl
...
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
and then regenerated the /etc/mail/sendmail.cf file and restarted senmaild, and started saslauth service. Still I can't send an e-mail.

General :: Safe To Remove Sendmail By Running "yum Erase Sendmail" And Let Postfix Handles "mailx" Also?
Sep 5, 2010I have installed postfix and dovecot on my server and thought postfix will not only take SMTP connection from my e-mail client like Outlook, but also handles "mailx" commands from the server. However, it looks like sendmail is still responsible for sending mails from "mailx". I tested this by turning it on/off using "service sendmail stop" and "service sendmail start". Mails sent using "mailx" will only be sent when sendmail is up. When I did "yum info sendmail", it lists sendmail as an installed package. Is is safe to remove sendmail by running "yum erase sendmail", and let postfix handles "mailx" also?

The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect.

Server :: Sendmail Not Reading Default Sendmail.cf ?
Apr 1, 2010I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.
So in other words, the following works great:
However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:
I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.
Why sendmail is not reading my sendmail.cf?
I'm running Sendmail version 8.14.2 on Fedora Core 8.

Jan 17, 2011I need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.

Jan 15, 2011I have a apache server installed on my system which I use for testing out stuff like wordpress and forums. I use the server for learning stuff only. I would like to know what do I have to do so that these blogs, forums etc can send an email when someone registers. I guess most of these use sendmail to send email. So how do I configure sendmail so that it sends email using my gmail address and smtp. Also I think there is a php mail option (or something called like that) that allows us to send email without having sendmail installed.

Jan 24, 2011Can connect to our mail server using telnet onto port 25 and this works correctly, 'ehlo whatever' shows output as expected.
However using a mail client to connect it gives an authentication error and the following appears in the maillog file;
did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
what to look for in the config, this works correctly on our development box but not on our production server. Could it be another program is interfering with the connection?
Sendmail is running in standalone mode not through the xinetd daemon.
I am using the PLAIN AUTH method as to try and avoid getting more errors.

General :: Add PHP User As Trusted Sender In Sendmail?
Jul 7, 2010I have a mail script that has been running on my website for several years. One problem I had with the script was when a bad address was put in, the mail was rejected to the server rather than to the sender. I have now recently added a fifth parameter to the mail script using the -f sendmail option to set the return path.
PHP Code:
$mailsend=mail("$email","$subject","$emess","$ehead","-f$adminEmail");
The PHP manual says this:
Quote:
The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a 'X-Warning' header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is /etc/mail/trusted-users. I do have the 'X-Warning' header on e-mails sent with this script and have asked my server administrator for some help in adding "the user that the Web server runs as" as a trusted user.
