[SOLVED] [Email] I can't send email from my server

thomas2004ch · 03-30-2015, 06:30 AM

Hi,

As I try to send an email with following command:

Code:

 echo "this is a test" | mail -s "Test" thomas.2004@mycom.com

I got nothing.

I check the postfix and it's ok. I check the port with

Code:

netstat -ntpl  |grep "127.0.0.1"

and I get:

Code:

tcp        0      0 127.0.0.1:2528              0.0.0.0:*                   LISTEN      30157/java
tcp        0      0 127.0.0.1:4449              0.0.0.0:*                   LISTEN      30157/java

tcp        0      0 127.0.0.1:3447              0.0.0.0:*                   LISTEN      30157/java
tcp        0      0 127.0.0.1:6999              0.0.0.0:*                   LISTEN      30157/java
tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      2741/master

This must be OK, right?

Check /var/log/maillog and see if there's anything in the logs.

You have to set configuration files of postfix for each email address. Search web it has many examples.

I've checked but there is no any log.

By another linux server where I can send email succeffully, I can see log in the /var/log/maillog.

what's the output of:

Code:

postqueue -p

thomas2004ch · 03-30-2015, 07:48 AM

The output look as follow:

Code:

...
C93CE700D8*  223216 Mon May  5 04:02:04  root@s001is35-test.ad001.mycom.grp

D96DF701B0*  114259 Fri Dec  5 04:02:02  root@s001is35-test.ad001.mycom.grp

DBB887009C*  114444 Tue Jan  6 04:02:03  root@s001is35-test.ad001.mycom.grp

EB6BF70132*  114052 Sun Aug 10 04:02:03  root@s001is35-test.ad001.mycom.grp

187C8701A5*  184203 Tue Apr 29 04:02:03  root@s001is35-test.ad001.mycom.grp

The date are quit strange.

Ok, so mails are sitting in the queue, you might find the test mails you tried to send at the end of the queue.

And you say there's NOTHING in /var/log/maillog? Do you mean that it's empty or that you couldn't see anything related to the mails you tried to send?

thomas2004ch · 03-31-2015, 01:59 AM

Sorry for the late reply.

I mean there is no any log written in to the mailog.

But as I use the following command:

Code:

echo "Test mail" | mail -vvv -s "Test mail" thomas.2004@mycom.com

I see follwoing in console:

Code:

Mail Delivery Status Report will be mailed to <root>.

and following in the maillog:

Code:

...
Mar 31 08:58:53 s001is35-test postfix/cleanup[28285]: fatal: open database /etc/postfix/recipient_canonical.db: Invalid argument
Mar 31 08:58:54 s001is35-test postfix/master[4081]: warning: process /usr/libexec/postfix/cleanup pid 28285 exit status 1
Mar 31 08:58:54 s001is35-test postfix/master[4081]: warning: /usr/libexec/postfix/cleanup: bad command startup -- throttling
...

Seems the db is corrupt?

Fix that first and then keep trying and checking maillog

thomas2004ch · 04-08-2015, 03:20 AM

I solved the porblem now. I did as follow:

(i) stop postfix:

# service postfix stop

(ii) remove the hash map file:

# rm /etc/postfix/recipient_canonical.db

(iii) generate the hash map file:

# postmap /etc/postfix/recipient_canonical

(iv) start postfix:

# service postfix start

Cool, glad you got sorted.
