Eu hospedo 2 domínios da web (domain1.com e domain2.com) em um servidor Linux do CentOS 6.6 com 4 endereços IP.
O postfix 2.6.6 aceita e-mails para [email protected] e [email protected] e os encaminha para [email protected] e [email protected] . Aqui trechos dos arquivos de configuração:
/etc/postfix/main.cf
inet_interfaces = all
inet_protocols = ipv4
virtual_alias_domains = domain1.com domain2.com
virtual_alias_maps = hash:/etc/postfix/virtual
smtp_generic_maps = hash:/etc/postfix/generic
/ etc / postfix / virtual
[email protected] [email protected]
[email protected] [email protected]
Meu problema é que a primeira pessoa (meu pai, cujo negócio é desde 1990 na internet) se torna um monte de mensagens de spam. Eu uso o Spamassassin para rejeitar esses e-mails, mas alguns ainda chegam e, quando encaminhados para o [email protected] , fazem com que o Google estrangule o meu servidor:
DFC32800849 3412 Fri Jan 30 11:40:38 [email protected]
(host alt1.gmail-smtp-in.l.google.com[74.125.130.26] said: 421-4.7.0

[email protected]
Isso afeta a segunda pessoa, que recebe e-mails para [email protected] depois de longos atrasos.
Minha pergunta é se é possível configurar o Postfix para que ele use diferentes endereços IP (já que meu servidor possui 4 deles) para encaminhar os e-mails?
Obrigado e abaixo está a saída atual "postconf -n":
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
header_checks = pcre:/etc/postfix/header_checks
html_directory = no
inet_interfaces = all
inet_protocols = ipv4
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man

myhostname = www.domain1.com
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtp_destination_concurrency_limit = 2
smtp_destination_rate_delay = 40s

unknown_local_recipient_reject_code = 550
virtual_alias_domains = domain1.com domain2.com
virtual_alias_maps = hash:/etc/postfix/virtual
ATUALIZAÇÃO:
Eu modifiquei meus arquivos de configuração como sugerido por undefined (obrigado!) e, em seguida, execute postmap /etc/postfix/transport e service postfix restart -
/etc/mail/master.cf :
smtp unix - - n - - smtp
smtp-1 unix - - n - - smtp -o smtp_bind_address=my_ip_3
smtp-2 unix - - n - - smtp -o smtp_bind_address=my_ip_4
/ etc / mail / transport :
[email protected] smtp-1:
[email protected] smtp-2:
Infelizmente, ainda vejo a antiga problemática my_ip_2 nos cabeçalhos de e-mail entregues.
Como posso verificar se os novos "transportes" estão sendo usados?
Aqui está o extrato do log após a alteração:

Não é o IP que eu especifiquei para smtp-1 ou smtp-2.
UPDATE 2:
Eu adicionei "-v" ao /etc/postfix/master.cf :
smtp inet n - n - - smtpd -o content_filter=spamassassin
....
smtp unix - - n - - smtp
smtp-1 unix - - n - - smtp -o smtp_bind_address=144.76.184.155 -v
smtp-2 unix - - n - - smtp -o smtp_bind_address=144.76.184.156 -v
....
spamassassin unix - n n - - pipe user=spam argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}
