Hello, everybody.

I'll try to translate Rodrigo's message from Spanish to English:


----------------------------------------------

Hello everybody_

I have the following question:

I have installed Centos 6.4

when running the following command:

1) MTA

alternatives --config mta

This is the output:

-----------------------------------------------
+ 1           /usr/sbin/sendmail.postfix
*  2           /usr/sbin/sendmail.sendmail

It seems that I am using postfix.

but I DON'T have postfix configured.

2) SENDING MAIL

echo "proof" | mail -s "subject of proof" account at gmail.com

That works fine when sending mails to GMAIL YAHOO...etc

but it doesn't work at all when I send mails to my personal account or my work mail account.


3 ) checking the logs:


localhost postfix/smtp[16415]: A33747AC93: to=<rodrigo at miaccount.cl>, relay=
mail.miaccount.cl[67.20.125.184]:25, delay=4.4, delays=0.11/0.01/2.9/1.4,
dsn=5.0.0, status=bounced (host mail.miaccount.cl[67.20.125.184] said:
550-Verification failed for <root at enum-server.localdomain> 550-The mail
server could not deliver mail to root at enum-server.localdomain.  The account
or domain may not exist, they may be blacklisted, or missing the proper dns
entries. 550 Sender verify failed (in reply to RCPT TO command))


Why can I send mails to gmail.com but not to a personal account?


I ask for some suggestions


thans to everybody.
