sendmail is unable to get access to the outside world? unable to send email?

cyberdome · 03-29-2014, 02:37 PM

Hello everyone,

I have done everything I can in my Sendmail configuration. I am using Fedora 20, I used Yum to install sendmail and sendmail-cf.

I added port 25 in my IPtables. I have added 192.168.1 RELAY in my access file,

I have forwarded the port on my ROUTER. check and verified with port scanner. http://www.whatsmyip.org/port-scanner/server/

Done everything I could. Still when I am sending email to my personal yahoo email address. It shows up in my local user mail directory.

Does not show up in my yahoo inbox.

Code:

for example --> $ mail - "Hello" boss@yahoo.com  ( control+D )
this is test email (control+D)

I do get a message after executing the mail command to my yahoo email., that I have mail in my /var/spool/mail/user

I have added port in my IPTABLES. I have not mess with the sendmail.mc file yet. In the fedora tutorial, it says not to mess with the file. I may have to edit the sendmail.mc possibly.

http://docs.fedoraproject.org/en-US/...ndmail-changes

I did try some changes in the sendmail.mc file but it is still not sending out email to my yahoo inbox.

https://fedoraproject.org/wiki/Archi...erver/Sendmail

In my httpd.conf file my SERVERNAME directive is set to 192.168.1.3:80 which is my local ip given by my router.

I am stuck at this now. I have no idea where to look from here?

Any help is greatly appreciated.

Hello Cyberdome,

1. Presumably after editing the sendmail.mc file you have rebuilt the sendmail config by performing /etc/mail/make?
2. At the time of attempting to send mail have you checked /var/log/maillog for error messages?
3. Many ISPs in an attempt to reduce the volume of spam being relayed through them require that you specify an SMTP server through whom you are relaying mail. Most will require that that you specify the SMTP server of the ISP that you are connected to. Thus in your sendmail.mc file yuo should have an entry that corresponds to : dnl define(`SMART_HOST', `smtp.SMTP_SERVERNAME.com')dnl where SMTP_SEVERNAME relates to the SMTP server name of your ISP. If you are not sure of the STMP server name for your ISP simply Google "SMTP YourISP"
4. Oops - forgot to add - I am also assuming that after adding the Relay entry to the Access file you rebuilt the file using: makemap hash /etc/mail/access.db < /etc/mail/access

Regards,

Rawcous!

Okay, thanks, I am setting up a Joomla Blog website. So, when anyone visits my blog and wants to register a account (just like setup at these Linux Forums). When they register, they will get a activation email from my server. But right now, It is not sending out emails. I register a dummy account on my blog and put my secondary email I have. did not go through. This is the end goal I am trying to do. So, changing the SMART HOST to my ISP.net , Would I need to provide my username and password, my ISP email address, and PORT # provided by my ISP?

thanks for the reply,

I noticed your running a EMAIL server yourself. Sendmail is very complicated and powerful program.

Hello,

Your ISP account details would only typically be required if say for example your server was connected to the internet via ISP A and you had user "JOHN" with your domain account who was trying to send / receive mail remotely whilst connected to the internet via ISP B - hope that make sense... In your case [B]SMART_HOST/B]would simply refer to the SMTP of your ISP - no account details would be required.

... and yes Sendmail is very powerful, along with Postfix being the most popular MTA's used - especially in real-life production environments.

See the following links, for example:

I have made the change in the sendmail.mc file, it is still not sending out emails to my YAHOO or GMAIL inbox. I am confused as to what I am doing wrong.

Hello,

1. As mentioned after editing the sendmail.mc file perform /etc/mail/make
2. Whenever you have any issues in Linux, i.e things don't work always check the log files - in this case /var/log/maillog - post a segment here obtained at the time of attempting to send mail.

Hello,

define(`SMART_HOST', `smtp.isp.net')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl

Connection timed out with smtp.isp.net

- entry from your maillog file

1. via the command prompt can you ping smtp.isp.net? or do you also receive a timeout? If it's smtp.verizon.net then I also receive a timeout - however this could simply be due to the servers being configured to block responses to ping requests.

2. If smtp.verizon.net is your smtp server see here: http://www.verizon.com/Support/Resid...sone/86782.htm This page indicates verizon are using port 465 - so replace 587 above with 465

1. As mentioned after editing the sendmail.mc file perform /etc/mail/make

I have done that.

2. Whenever you have any issues in Linux, i.e things don't work always check the log files - in this case /var/log/maillog - post a segment here obtained at the time of attempting to send mail.

I don't have a /var/log/maillog file. That is why I am unable to post output of a log file. I am running Fedora 20 with SELinux. So, I don't know where the file is? The only thing I found /var/log/mail/statistics file? when I do cat statistics. it shows nothing but jibberish.

3. How are you trying to send mail from your mailserver?

I am using the command shell from the linux server terminal window. I run the command.

mail -s "hello world" user@yahoo.com (control+D)
hello (control+D)
EOT

sorry about this. I changed it to 465, I send a email using command line. it says connection reset by isp.net.

I have no idea what I am doing wrong. If using 465, does my server need to setup SSL certificate. I have not setup the server for SSL.

cyberdome · 03-30-2014, 05:43 AM

here is the output for my sendmail port

netstat -ntlp | grep sendmail

Rawcous · 03-30-2014, 07:17 AM

Hello,

As per the link 465 is a direct replacement for 25. SSL would typically be on port 587.

You mentioned you don't have a /var/log/maillog but indicated that you have /var/log/mail/statistics file containing:

nothing but jibberish.

so presumably it's this file that contains:

As you have amended and rebuilt the sendmail.mc to include the change of outbound smtp port from to 465, I recommend that you restart the sendmail service to reflect the change if you haven't already done so - otherwise the 2 may conflict.

systemctl restart sendmail.service
