Package: nullmailer Version: 1:2.2+10~g7ed88a0-6 Severity: important Tags: upstream
Dear Maintainer, Some messages from nullmailer are rejected by my smart relay running Debian sendmaili, after it was updated with https://lists.debian.org/debian-lts-announce/2024/06/msg00004.html The faiing messages are typically from cron jobs returning a single line of text ending in a carriage return (\r). The problem can be reproduced by running echo -e "To: r...@example.com\n\nFoo\r"|nullmailer-inject Which results in 2024-10-02T11:09:08.179422+00:00 gustav nullmailer-send[453]: Starting delivery, 1 message(s) in queue. 2024-10-02T11:09:08.179444+00:00 gustav nullmailer-send[453]: Starting delivery: host: dilbert.example.com protocol: smtp file: 1727867348.32924 2024-10-02T11:09:08.179466+00:00 gustav nullmailer-send[453]: From: <bj...@gustav.example.org> to: <r...@example.com> 2024-10-02T11:09:08.179489+00:00 gustav nullmailer-send[453]: Message-Id: <1727867348.172026.32923.nullmai...@gustav.example.org> 2024-10-02T11:09:10.006453+00:00 gustav nullmailer-send[32925]: smtp: Failed: 421 4.5.0 Bare carriage return (CR) not allowed 2024-10-02T11:09:10.007814+00:00 gustav nullmailer-send[453]: Sending failed: Temporary error in sending the message 2024-10-02T11:09:10.007885+00:00 gustav nullmailer-send[453]: Delivery complete, 1 message(s) remain.
