We recently upgraded some systems from postfix 2.6.6 to postfix 2.7.4, and the behavior when trying to submit messages through the sendmail interface seems to have changed.
In the previous version, if a message exceeded the configured message_size_limit, it would look like this: $ (printf "From: r...@csupomona.edu\nTo: hen...@csupomona.edu\nSubject: big email test\n\n"; yes test | head -c 10000000) | /usr/sbin/sendmail -t postdrop: warning: uid=1005: File too large sendmail: fatal: henson(1005): message file too big With the new version, it now emits: $ (printf "From: r...@csupomona.edu\nTo: hen...@csupomona.edu\nSubject: big email test\n\n"; yes test | head -c 10000000) | /usr/sbin/sendmail -t sendmail: fatal: henson(1005): internal protocol error At first I thought something was broken with my new installation, but everything seems to be working ok other than this different message. Was this an intentional change? Accidental change? I've got something broken after all? The systems in question are running gentoo linux, with the following config: # postconf -n allow_mail_to_commands = allow_mail_to_files = biff = no command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = //usr/lib64/postfix data_directory = /var/lib/postfix fast_flush_domains = forward_path = html_directory = /usr/share/doc/postfix-2.6.5/html local_transport = error:local delivery is disabled mail_owner = postfix mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man message_size_limit = 10240000 mydomain = unx.csupomona.edu mynetworks_style = host myorigin = csupomona.edu newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.5/readme relayhost = [smtp.csupomona.edu] sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail setgid_group = postdrop Thanks... -- Paul B.
