Bug#1112303: Please support disabling SMTP pipelining via local macro

[Joey Schulze]

Package: exim4-config
Version: 4.96-15+deb12u7
Severity: wishlist
Tags: patch

Hi!

In one of my setups there seems to be a problem in connection to SMTP
pipelining which results in mails not reliably delivered.  After
disabling SMTP pipelining it worked well.

This I'd like to have a possibility to disable this feature via local
macros instead of editing configuration files directly.

Based on the version of exim4 in bookworm I provide a patch to be
integrated with the Debian build system.  The patch applies to the
version in unstable as well.

The attached patch adds two macros that can be set locally in the file
exim4.conf.localmacros

REMOTE_SMTP_SMARTHOST_HOSTS_AVOID_PIPELINING
    Disable SMTP pipelining for smarthosts

REMOTE_SMTP_HOSTS_AVOID_PIPELINING
    Disable SMTP pipelining for certain hosts

Regards

	Joey
