Sending Mail From Command Line

I'm trying to send all root's mails to an external e-mailaddress, but for some reason I can't get it to work.

I've edited /etc/aliases with the following rule:

root: <myexternal@email.address>

and run newaliasses after, which would run without any errors.

I can run: echo "Testing" | mail -s "Server Testing" <myexternal@email.address>
just fine without any issue and it's being delivered correctly to my external address.

But when I run: echo "Testing" | mail -s "Server Testing" root

I (first) get a "Deferred: 451 Temporary local problem - please try again later" error and when I then run: "Sendmail -OTimeout.hoststatus=0m -q -v" to flush the mailqueue it says everything is ok, but I then get a message saying I have new mail in /var/spool/mail/root and I don't get the mail on my external e-mailaddress.

I have no clue where to look next, hopefully you guys can point me in the right direction.

Just for completeness: I use mageia release 4 (x86_x64).

Hi all,

I am trying to configure sendmail on my OEL 6.5 running on VM.

I did below to set it :

1. # yum install m4 telnet mailx
2. # yum install sendmail sendmail-cf
3. # ps -ef | grep -v grep | grep -i sendmail
root 3805 1 0 05:58 ? 00:00:00 sendmail: accepting connections
smmsp 3815 1 0 05:58 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue

4. # netstat -an | grep :25 | grep tcp
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN

5. vi /etc/mail/sendmail.mc

From:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

To
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

6. # m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

7. # service sendmail restart

8. # vi /etc/mail/local-host-names
oracle.com

Now if I am sending mail from 1 user (root) to other user (oracle)

$ mail -s "Test mail from root" oracle
Hello this is the test mail
.
EOT

and checking mail log under /var/mail/oracle, its passing successfully.

But when trying to send the same from root user to my company outlook account not gtting any mail.

mail -s "Test mail from root" abc.xyz@aaaa.com (trying to send to my outlook account)

Getting below error on /var/log/maillog :

Please suggest if something I missed out or any other problem

Hi All,
We have some shell scripts which will send emails about backup, alerts etc using mail command. Example.
Code:

echo "Test Mail" | mail -s "Test" me@mydomain.com

I guess the above command just connect port number 25 of our mail server even if we do not define any port number. Now I would like add smtp port number as 587 in all of the bash scripts. I googled for this but could not get whatever I am expecting. So expecting your kind reply to define smtp port number as 587 in all of the bash scripts.

Thanks in advance.

Hi All,

I am trying to send email using telnet to smtp as mailx and other functionality is restricted by administrator.

I am not able to figure out as how to attach any text or any file using the below.

I am following all instructions and steps as shown at http://exchange.mvps.org/smtp_frames.htm

1. telnet <servername> 25
2. helo <your domain name><enter>
3. mail from: <your Email Address><enter>
response should be as follows
250 OK - mail from <your Email address>

rcpt to: <recipient address><enter>
response should be as follows
250 OK - Recipient <recipient address>

data<enter>
response should be as follows
354 Send data. End with CRLF.CRLF

To: <recipient's display name><enter>
From: <your display name><enter>
Subject: <Subject field of Email message><enter>
<Enter you body text><enter><enter> . <enter>
response should be as follows
250 OK

quit<enter>

I congifured postfix,dovecot and squirrelmail in my server. Now I am able to send mail from my webmail ( squirrelmail ) to my office email address, while I am trying to reply for that mail I didnt face any error. Mail logs also show that mail has been deleivered. But I didnt get any emails in my inbox, all the folders except inbox( sent, trash and drafts) were working fine. But I dont know what is the issue with inbox. I have checked all the configuration files.
I am using Ubuntu 12.04.5 LTS .any one have idea about this issue?

Hi All,
We have qmail server running on RHEL6.5. We have already made sure that our server is not acting as an open relay with the help of http://mxtoolbox.com/diagnostic.aspx.
But still anyone can telnet to our domain and send fake emails to anybody@ourdomain.com. For example Code:

telnet mail.ourdomain.com 25
helo mail.ourdomain.com
mail from: unknown@anyname.com
rcpt to: anyemailid@ourdomain.com
data
from: "Any Unknow name" <unknown@anyname.com>
to: "Some user Name" <anyemailid@ourdomain.com>
subject: Testing MTA with telnet

Hi,
This way anybody can fool us.

Regards,

.
quit

So can anybody pls help me to prevent this. I meant to say, we should not block port 25, instead it should verify whether or not "from email id" is exist in our domain, if it is exist then it should ask for the password also or if it is not exist then also it should not take us to next step. Because as per above example anybody can fool us as the mail is coming from outside but it is just from our domain to our domain without any authentication!!!
Expecting your kind help to block sending mails in this way.

I'm new to Sendmail and I want to be able to grab various stats from the Linux servers that I manage to monitor them.

Sendmail is running on my main Linux server and I can go thru the motions of sending an email to my MS Outlook client, which is what I use at work.

However I never get the email and if I check /var/spool/mqueue, I don't see any email queued up, and if I put a tail -f on /var/log/mail, this is what I'm seeing:

Code:

Feb  3 10:20:38 computername sendmail[31432]: t13GKcri031432: from=cmmiller, size=77, class=0, nrcpts=1, msgid=<201502031620.t13GKcri031432@mailserver.com>, relay=cmmiller@localhost
Feb  3 10:20:39 computername sendmail[31433]: t13GKcVO031433: from=<cmmiller@mailserver.com>, size=425, class=0, nrcpts=1, msgid=<201502031620.t13GKcri031432@mailsever.com>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]
Feb  3 10:20:39 computername sendmail[31432]: t13GKcri031432: to=myemailaddress@com, ctladdr=cmmiller (602/602), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=30077, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (t13GKcVO031433 Message accepted for delivery)
Feb  3 10:20:39 computername sendmail[31435]: t13GKcVO031433: to=<myemailaddress@com>, ctladdr=<cmmiller@mailserver.com> (602/602), delay=00:00:00, xdelay=00:00:00, mailer=smtp, pri=120425, relay=smtp.server. [192.138.40.216], dsn=2.0.0, stat=Sent (+OK message queued for delivery.)

Not sure what to troubleshoot here, and if anyone can point me to better information, thanks.

hello

first year of learning linux and bash script
Now i wrote a bash script with a function.
Today i recieved a email from my teacher that 1 function only can have 1 command and no more then 1?

thats a part of the script

Code:

function tx_unreachable_msg()
{
LOGLINE="[$DATE] no ip service unreachable"
typewriter "$NOIPSERVICE niet bereikbaar" .1
sleep 1 
typewriter "Mail wordt verzonden naar $email" .1
mail -s "NO ip mail error" "$email"<<EOF
dynupdate.no-ip.com niet bereikbaar @ $DATE
EOF
}

it's part dutch part english but the point is that the first LOGLINE is forbidden in the function because i use the functie to send a mail end not to write a logline but that's a part of the command in my case?

So what does this function?
If the no ip service is unreachable then it's write to /etc/var/log/no-ip and after the sleep it's send a simpel mail to the adres in the variabele mail.

i read here at the first line:
Quote:
Shell functions are a way to group commands for later execution using a single name for the group.
so is it true that my function is wrong and so no can someone point me to a website where it's say that more commands are allow in 1 function0

grts b

I am having some strange issues with sendmail at the moment.

When a mail comes into my sendmail server, where it is then relayed onwards, the sendmail server for whatever reason tries to forward it a hostname that it shouldn't.

Have no idea where it gets this hostname from in the first place as it should be sending it to a mail.full.domain.name server.

So my question is, does anyone exactly know how sendmail performs a hostname or DNS lookup and where it's cached. The strange thing is though that a restart of the sendmail service fixes this, yet it reappears sometimes, usually when we have some network issue in the back-end.

One would think that sendmail would clear its cache every few minutes. Or does it leverage something else to perform this lookup.

Hello Guys,

I set up a mail server in a LINUX environment using iRedMail.The users can only send and receive e-mail throughout the local network, not from the Internet. I would like to know the steps to follow for the configuration. Also i want the windows users to be able to send and receive e-mails through that mail server.
Thanks to help...
