настройки почтового сервера ubuntu и файл/etc / hosts

Это мой файл/etc / hosts

127.0.0.1       localhost.localdomain                   localhost
127.0.1.1       ubuntu-server.xx.com                ubuntu-server
193.77.xx.xx   mail.xx.com                         mail

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

это правильная конфигурация для моего почтового сервера. Я за маршрутизатором, поэтому я не знаю, можно ли использовать мой IP для mail.xx.com и 127.0.0.1 для localhost

проблема заключается в том, что я могу получать почту, но когда я посылаю его, я получаю

Oct 17 21:29:32 ubuntu-server postfix/smtpd[2453]: warning: SASL authentication failure: Password verification failed
Oct 17 21:29:32 ubuntu-server postfix/smtpd[2453]: warning: my.router[192.168.1.1]: SASL PLAIN authentication failed: authentication failure
Oct 17 21:29:34 ubuntu-server postfix/smtpd[2453]: warning: my.router[192.168.1.1]: SASL LOGIN authentication failed: authentication failure

EDIT:

может быть проблема порта. я ловлю эти порты.

POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
Secure SMTP (SSMTP) - port 465
Secure IMAP (IMAP4-SSL) - port 585
StartTLS - port 587 
IMAP4 over SSL (IMAPS) - port 993
Secure POP3 (SSL-POP) - port 995

Cannot find the smtp_sasl_password_maps parameter in main.cf.
Client-side SMTP AUTH cannot work without this parameter!
