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@xxxxxxxxx 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@xxxxxxxxxxxx>, 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@enum-server.localdomain> 550-The mail server could not deliver mail to root@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. ---------------------------------------------- El 04/03/14 15:40, Rodrigo Pichiñual Norin escribió: > Hola a todos: > > Tengo la siguiente interrogante: > > Resulta que tengo centos 6.4 > > al ejecutar el siguiente comando: > > 1) MTA > > alternatives --config mta > > la salida es la siguiente: > > ----------------------------------------------- > + 1 /usr/sbin/sendmail.postfix > * 2 /usr/sbin/sendmail.sendmail > > Lo cual indica que esta usando postfix. > > pero NO TENGO configurado postfix. > > 2) ENVIAR MAIL > > echo "prueba" | mail -s "asunto de prueba" cuenta@xxxxxxxxx > > esto funciona enviando mail a GMAIL YAHOO...etc > > pero no funciona enviando mail a mi cuenta personal o de empresa. > > > 3 ) chequear log > > > localhost postfix/smtp[16415]: A33747AC93: to=<rodrigo@xxxxxxxxxxxx>, 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@enum-server.localdomain> 550-The mail > server could not deliver mail to root@enum-server.localdomain.
