Ok I will describe my goal:
There is a server. On it runs postfix. All mail is sent via localhost (or 127.0.0.1). Meaning, I run a command and mail is sent, nobody is connecting from outside and sending. I need to save to a custom DB the mail after any headers are changed/added by postfix. So if user X@MyMail sends a mail M, postfix (perhaps) adds headers to M, creating M-Final. I want to save M-Final to a table, (User, SentOrReceived, MailContent) (X@MyMail, Sent, M-Final). I then want the mail to be sent. I would like the command to save M-Final to be something like: SentToStore sender recipients If for whatever reason, the save of M-Final to the DB fails, I want the mail to either retry later or bounce. -- I am attempting to do this with the Posfix After-Queue Content Filter. It works, except that mail is never sent because it keeps on hitting the filter, re-added to the queue, etc. -tim On 3/19/14, li...@rhsoft.net <li...@rhsoft.net> wrote: > Am 19.03.2014 20:59, schrieb Tim Prepscius: >> so let's say I wanted to do what Lewin said, >> >> have normal mail on 25, and then special non filtered mail (mail that >> has already gone through the filter) on some other port, let's say >> 10025 > > then you just configure that listener and avoid asking questions > in context of pickup and sendmail binary because they are both > not involved > > if your inital post would have had the same content as above the > first reply would have been that clear - describe your goal and > not what you have done or think has to be done to reach it > > -o mynetworks=192.168.196.0/24 is in such setups typically > the address of the delivering filter and not a network, in > mayn cases just 127.0.0.1:10025 has the same result > ____________________________________________ > > /etc/postfix/main.cf > filter_smtpd_recipient_restrictions = permit_mynetworks, reject > > /etc/postfix/master.cf: > 10025 inet n - y - 60 smtpd > -o mynetworks=192.168.196.0/24 > -o smtpd_client_connection_count_limit=60 > -o smtpd_recipient_restrictions=$filter_smtpd_recipient_restrictions > -o receive_override_options=no_header_body_checks,no_milters > -o local_header_rewrite_clients= > -o sender_dependent_relayhost_maps= > -o content_filter= > -o smtpd_delay_reject=no > -o smtpd_client_restrictions= > -o smtpd_relay_restrictions= > -o smtpd_helo_restrictions= > -o smtpd_helo_required=no > -o smtpd_sender_restrictions= > -o smtpd_sender_login_maps= > -o smtpd_data_restrictions= > -o smtpd_end_of_data_restrictions= > -o smtpd_restriction_classes= > -o smtpd_error_sleep_time=0 > -o smtpd_soft_error_limit=1001 > -o smtpd_hard_error_limit=1000 > -o smtpd_client_connection_rate_limit=0 > -o smtpd_client_recipient_rate_limit=0 > -o smtpd_peername_lookup=no > -o smtpd_use_tls=no > -o smtpd_tls_security_level=none > -o smtpd_sasl_auth_enable=no > -o smtpd_reject_footer= > -o max_idle=1h > -o max_use=1000 > > >> At the end of the example filter script there is a sendmail command. >> Is there anyway to have this work with this scenario? >> >> http://www.postfix.org/FILTER_README.html >> >> On 3/19/14, li...@rhsoft.net <li...@rhsoft.net> wrote: >>> as lonf you are talking about pickup there is no port >>> involved at all and no smtp/smtpd setting is relevant >>> because it's just not SMTP >>> >>> Am 19.03.2014 20:49, schrieb Tim Prepscius: >>>> I'm looking through the docs of sendmail, seeing how I can get it to >>>> send to a specific port.
