Hm. Whereas this is also an idea for anything session-like (not explicitly cleared thereof that is) i have not thought of, it does not solve "the problem of directory access". But as this seems to me only my problem (occasionally container support shows up, but that is something different .. i think) i am fine with as it is. But i will try out Wietse Venema's suggestion soonish, ie, basic installation in /etc/ but which does not drive the real postfix, and then "making the maildrop available" to the basic installation. --steffen | |Der Kragenbaer,The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

The default Postfix directory (the one compiled into the executables) must exist, and hold at a main.cf file for Postfix local submission to work. - postdrop(1) is setgid, and when invoked by a non-privileged user only trusts MAIL_CONFIG if it is either the default configuration directory, or that one of one of the configured secondary instances. - The spool directory must exist, and have a maildrop subdirectory with the right ownership. > > So last i tried.

If you do not compile custom, but still want a custom configuration (directory), you need command line options. Yes, one could write a shell wrapper around /usr/sbin/sendmail which applies the necessary hints (and needs to be reinstalled as a replacement after each update). But this works only for root. Unless the path all through to the configuration etc is +[r]x for all users -- and this counteracts the host-specific configuration as i it use for the other daemons i drive: these live under /root/hosts/$HOSTNAME/. Actually, you know, this is all git(1) driven; some branches (bin, linux.kconfig, ..., $HOSTNAME), and then you join only those branches into $HOSTNAME that are needed, and then you "git push $HOSTNAME" to that host. Each host only has its own branch. On each $HOSTNAME you can use bin/backup.sh (which reads /root/hosts/$HOSTNAME/backup) to backup some host-specific files (mostly resolv.conf, hosts, and whatever is only there), commit that, and then you can "git fetch" that back to the "super server" which has all the git branches. This sounds messy but does not require any external software like puppet or how it is called and such (Ansible?), and for hosts with identical hardware you effectively can share branches with just a few lines of "git diff HOST1 HOST2". |Originally.

I've changed the default master.cl to have: smtp inet n - n - - smtpd -o smtpd_tls_security_level=none -o smtp_tls_security_level=none -o smtpd_sasl_auth_enable=no I would comment this section out entirely, you do not need nor should you be using port 25 smtp unless your postfix instance is going to receive mail from other servers on the internet. 127.0.0.1:submission inet n - n - - smtpd -o smtpd_tls_security_level=none -o smtp_tls_security_level=none -o smtpd_sasl_auth_enable=no Disabling tls is not a great idea here, but is okay since you're limiting it to localhost. Do keep in mind that you do not need this at all if you go by my suggestion above to use the sendmail binary (which is properly configured by default). and main.cf changes: # myhostname is not a valid internet name, but is in /etc/hosts myhostname = pippin120.gdc.com mydomain = gdc.com These are fine, although not really required or relevant if you're only doing delivery to local mailboxes. inet_interfaces = 127.0.0.1 This is fine, although it's redundant with the specified 127.0.0.1 for the submission service above. It also won't matter if you end up just using the sendmail binary as suggested. That said, you can set this to loopback_only or localhost for a bit more flexibility. mydestination = $myhostname, localhost.$mydomain, localhost mynetworks = 192.168.0.0/24, 127.0.0.0/8 If you use the sendmail binary then you can set this to blank (mynetworks=) # Try to avoid TLS smtpd_tls_security_level = none smtp_tls_security_level = none smtp_sasl_auth_enable = no smtp_use_tls = no You forgot: smtpd_tls_auth_only = no Peter ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
