Dear Exim Community,We have encountered issues using Exim4 in a microservices environment, such as disappearing logs when multiple containers write to the same log files and lock file issues with a shared spool directory. To address these, I propose a collaborative project to enhance Exim4 for cloud compatibility, focusing on robust log management and optimized spool directory usage. I request the community's help in creating a project plan outlining objectives, deliverables, development effort, and timelines. This plan will be presented to business stakeholders for sponsorship. Your expertise is crucial. Please share your thoughts and availability for a discussion. Regards Nasier Jaffer
On behalf of the exim project I must decline this request. We are a project with a tiny group of contributors and we do not engage in bespoke customisations. For your logfile issues you should spend some time debugging your container workflow as exim does not have any problem writing logs when multi-instantiated on a normal machine. There is also the FAQ entry you should have found during your initial debugging. https://github.com/Exim/exim/wiki/Q0073 Q0073: I'm seeing log file corruption, with parts of log lines getting mangled by other log entries. A0073: The only time this has been seen is when several servers were writing to the same log files over NFS. Exim assumes that its log file is on local disk, and using NFS, especially for more than one server, will not work. The same issues will likely apply when running multiple containers against a shared spool. -- Bernard Quatermass
