Hi to everybody. I'm realizing a postfix mailserver following this howto: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny Basically I want to hold all emails to be sent (I'll send them manually when I want), plus I want to relay all the emails to different smtp servers (depends of the email). So, more or less the main.cf of postfix look like that (I'll post just the important parts): Code: # TLS parameters smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_tls_CAfile = /etc/postfix/cacert.pem smtpd_tls_received_header = yes smtpd_tls_ask_ccert = yes smtpd_tls_loglevel = 1 smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_tls_cert_file = /etc/postfix/smtpd.cert smtp_tls_key_file = /etc/postfix/smtpd.key smtp_use_tls = yes smtp_tls_scert_verifydepth = 5 smtp_tls_loglevel = 1 smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_type = cyrus smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = $smtp_sasl_security_options smtp_sasl_tls_verified_security_options = $smtp_sasl_security_options smtp_tls_loglevel = 2 smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination relayhost = virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_mailbox_base = /var/vmail transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf relay_domains = mysql:/etc/postfix/mysql-virtual_relaydomains.cf sender_dependent_relayhost_maps = hash:/etc/postfix/bysenderrelay defer_transports = hold default_transport = hold proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps As users I've email from my main mailserver and emails from gmail, hotmail, yahoo, etc... To relay emails to gmail(or every smtp server that require CA), I've created a CA (following this howto: http://www.marksanborn.net/linux/send-mail-postfix- through-gmails-smtp-on-a-ubuntu-lts-server/). The problems that I've are: 1) I've setup in bysenderrelay the relay policy dependent of the sender, and in the database mail_transport(used by mysql-virtual_transports.cf), I've write all local emails, like that: Code: [email protected] : [email protected] : I did't put the value: Code: * smtp:[mail.domain.com] because otherwise I was not able to use the feature sender_dependent_relayhost_maps (all the email not direct to an internal account will be relayed to mail.domain.com). It's working fine for internal emails, but if I've as local email [email protected] and I want to send an email to [email protected], postfix think that gmail is a local domain and he believe that [email protected] is a local email. 2) After the configuration of the CA, I'm able to relay correctly emails to gmail and hotmail, but not to yahoo (I know that yahoo is working even without SSL, but I want that postfix will work with all the servers) 3) about the mail queued(the ones that needs to be sent), there is a way to see the subject of them? With mailq I can not see it I hope somebody can give me some suggestions... Thanks Michele
About the problem n.1, I guess the problem is in the tables mail_domains. Basically in postfix I've: Code: virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf and in that file there is this query: Code: SELECT domain AS virtual FROM mail_domains WHERE domain = '%s'; Now, in the table mail_domains I've the domain 'gmail.com', because I've some local email addresses with gmail. So with 'gmail.com' in mail_domains, I can correctly send internal emails, but not to external gmail accounts. If I remove 'gmail.com' from mail_domains, I'll send correctly emails to external gmail accounts, but no anymore to the internal gmail accounts... What I'm doing wrong? Thanks Michele
As far as I can see, the idea to solve the point n.1 should be: - since the nexthop destination is taken from relay_transport, sender_dependent_relayhost_maps and relayhost, I'll put the local emails as result of relay_domains (with relay_tranport=virtual) and the external emails in sender_dependent_relayhost_maps. The problem is that the postfix variable %s is giving me the domain of the sender, not the complete email address... and I can not match what I want in the select of relay_domains. I tried using also %u or %d, but nothing... Any idea? Thanks Michele
