Postfix - distribution of mail users not working

Question

I have problem with distribution emails, I need email from domain @cokdeje.cz send to user forexample info, from domain @surfujeme.cz to another, etc.

/etc/postfix/main.cf

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = no
readme_directory = no
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
myhostname = mail.surfujeme.cz
virtual_maps = hash:/etc/postfix/virtual
alias_database = hash:/etc/aliases
mydestination = $myhostname, /etc/postfix/domains
relayhost =
mynetworks =
mailbox_size_limit = 0
recipient_delimiter =
inet_interfaces = all
myorigin = /etc/mailname
default_transport = smtp
relay_transport = smtp
inet_protocols = all
home_mailbox = Maildir/

My virtual users (it's probable not work):

/etc/postfix/virtual

webcreating.cz  DOMAIN
@webcreating.cz         info

surfujeme.cz    DOMAIN
@surfujeme.cz           info

frosty22.cz     DOMAIN
@frosty22.cz            info

e-lekce.cz      DOMAIN
@e-lekce.cz             info

cokdeje.cz      DOMAIN
@cokdeje.cz             info

zujimode.cz     DOMAIN
@zujimode.cz            zujimodecz

And my virtual users,

/etc/passwd

info:x:1001:1004:Vít Ledvinka,,,:/home/info:/sbin/nologin
zujimodecz:x:1002:1005::/home/zujimodecz:/sbin/nologin
...

And /etc/postfix/domains

zujimode.cz
surfujeme.cz
cokdeje.cz
frosty22.cz
e-lekce.cz

I add user to file virtual, run postmap /etc/postfix/virtual but still all messages are in info mailbox, but when I delete some row from virtual file (example I remove: @zujimode.cz zujimodecz email cannot send to this domain, but when I write anything like username (info/zujimodecz/elekce/..) still all emails are in info mailbox.

Thanks so much for help! I work with it for one week, but I can't solve it ;(

Answer 1

I make some corrects, and now all emails are stored by $mydomain:

main.cf

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = no
readme_directory = no
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
mydomain = surfujeme.cz
myhostname = mail.surfujeme.cz
alias_maps = hash:/etc/aliases
virtual_alias_maps = hash:/etc/postfix/virtual
alias_database = hash:/etc/aliases
virtual_alias_domains = /etc/postfix/domains
mydestination = $myhostname localhost /etc/postfix/domains
relayhost = 
relay_domains = $mydestination
mailbox_size_limit = 0
recipient_delimiter = 
inet_interfaces = all
myorigin = $mydomain
default_transport = smtp
relay_transport = smtp
inet_protocols = all
home_mailbox = Maildir/

virtual

webcreating.cz  DOMAIN
@webcreating.cz     info

surfujeme.cz    DOMAIN
@surfujeme.cz       info

frosty22.cz DOMAIN
@frosty22.cz        info

e-lekce.cz  DOMAIN
@e-lekce.cz     elekcecz

cokdeje.cz  DOMAIN
@cokdeje.cz     cokdejecz

zujimode.cz DOMAIN
@zujimode.cz        zujimodecz

---

When send email to some domain:

anything@surfujeme.cz
anything@zujimode.cz
anything@cokdeje.cz

Postfix ignore domainname and use domain from main.cf => setting myorigin which is from mydomain and in virtual file find correct user info.

How I repair it? I don't need ignore domain name ;( I try it for 1 week, still nothing.

Answer 2

You should have virtual domains in the virtual_alias_domains and virtual_maps_domains configuration settings, not in mydestination as you currently do.

Answer 3

Did define the domains in the virtual-file?

it needs to look like this:

example.com  ANYTHING
foo@example.com some-user
bar@example.com some-other-user
@example.com catch-all-user
