Postfix wrong domain appending problem to @
 

Here is my main.cf:

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = all
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
mydestination = $myhostname, $mydomain, localhost.localdomain, localhost
mydomain = dom1.com
myhostname = mail.dom1.com
mynetworks = 127.0.0.0/8
myorigin = /etc/mailname
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject _unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = dom1.com
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous
smtpd_sasl_type = dovecot
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_domains = /etc/postfix/virtual/vhosts
virtual_alias_maps = hash:/etc/postfix/virtual/valias

/etc/mailname:

dom1.com

/etc/postfix/virtual/vhosts:

dom2.org

/etc/postfix/virtual/valias:

dom2.org DOMAIN

name@dom2.org name

i do the postmap /etc/postfix/virtual/valias when if i change smth in there
and i restart postfix anytime i change smth in main.cf

but still mail from dom2.org has name@dom1.com on the sender part when i recieve the mail i sent to my gmail acoount.

Can ayn1 tell what's wrong?

Did you set the correct sender address in your email client?

No, i did it and it has the required domain name at the sender part thanks a lot!!!!!! : )
But when i send it from the web interface, domainname.tld/squirrelmail it still has the primary domain appended.

Do you think it might be related to the mail server i'm using? I don't know if I must set up a new mail server for that or if i can just use the older one (mail.1st_domain.tld) as the mail server.
thnx again.

You must also set the correct sender address in your webmail program.

ok i did that too, and that was quite stupid for me not to be able to do it my ownself.

Thnx a lot.
