(nie)Wysyłanie maili z terminala z wirtualizacją Proxmox

[IceManSpy 4]

Cześć

Mam pewien problem z postfixem. Kupiłem Kimsufi a na nim zainstalowałem Proxmoxa.

Na tym Proxmoxie mam utworzone kilka kontenerów w tym kontener jako "serwer pocztowy".

Poczta ogólnie działa w obu kierunkach dla utworzonych kont pocztowych.

Niestety nie działa mail z terminala na Proxmox na adres, którego poczta jest skonfigurowana na "serwerze pocztowym".
Tzn na "serwerze pocztowym" mam mail@moj_adres.pl , a z Proxmoxa chce wysłać maila na ten adres.
Z zewnątrz mogę bez problemów wysyłać i odbierać na powyższy adres.

Jak mogę skonfigurować postfixa na Proxmox, aby działała "do środka" ? Potrzebuję wysyłać sobie maila o wykonaniu jakiegoś zadania w Cronie.

 

Funkcja mail z Proxmoxa może też wysyłać maile z terminala na zewnątrz (na adres nie zdefiniowany w "serwerze pocztowym".

Potrzebne porty mam przekierowane na ten kontener (iptables - REVERSE_DNS to adres serwera matki):

DNAT tcp -- anywhere REVERSE_DNS tcp dpt:pop3 to:192.168.0.100:110
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:imap2 to:192.168.0.100:143
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:ssmtp to:192.168.0.100:465
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:submission to:192.168.0.100:587
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:imaps to:192.168.0.100:993
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:pop3s to:192.168.0.100:995
DNAT tcp -- anywhere REVERSE_DNS tcp dpt:smtp to:192.168.0.100:25

Konfiguracja postfixa na Proxmox:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

myhostname=REVERSE_DNS

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

alias_database = hash:/etc/aliases
#mydestination = $myhostname, localhost.$mydomain, localhost
#mydestination = localhost.localdomain, localhost
mydestination = $myhostname, localhost.localdomain, localhost

Konfiguracja postfixa na "serwerze mailowym" - do zarządzania kontami mailowymi używam ISPConfig 3:

biff = no

# appending .domain is the MUA's job.
