Bug#1003399: Correct configuration of Exim

Personally I am running spamassassin via the exiscan extension, using the spamd_address option in main configuration and the spam option in the data ACL. To get a report into the message you need to use, for example, a system filter. See the exim specification chapter 45.2 for more information. Always only references to the documentation but no usable examples. Specially for the introduced "tainted" problem. Indeed i am thinking that maybe Postfix is a better choice as MTA, because Exim seems to be more and more complicated to configure? That depends on what you intend to do. postfix is like menu of a restaurant: You can choose from the dishes if you like them. Exim is the fully equipped kitchen: You can do anything you like but you need some knowledge to do that. Indeed. There is another software with such a concept: Asterix PBN. But for Asterisk you can find many examples for detail problems out there. I would define an virtual mail system as email server for different domains, that can ideally be managed with entries in an database like Mariadb. That is not enough defition, I am afraid. I guess defining this is enough content for a Master's thesis. What is a "Master's thesis" ? Up to now i only know one standard virtual mail system integrated into https://www.ispconfig.de/ Greetings karsten

Security updates are done, if possible, by backporting the fix to the version currently in stable. The goal is to provide minimally invasive security updates that don't break existing systems, concentrating potentially breaking changes to the time when a new stable distribution is released. > > Spamassassin in YOUR configuration doesn't work any more.

Hello Marc, thank you for the response. Am 09.01.22 um 19:05 schrieb Marc Haber: Yes - the other possibility is to prevent upgrades of this package. That is a decidedly bad idea. Exim is a huge suid binary (a design one out never choose today, the concept was valid 25 years ago) and you need security updates for that. That's of course true. Hopefully the version of Exim will not change until the configuration could be adapted. Security updates will not need a new version of Exim within this stable distribution? But there are additional other problems like spamassasin does not work any more, so the configuration must be updated in many kinds. Spamassassin in YOUR configuration doesn't work any more. My systems using spamassassin via exiscan-ACL have not even ridden a bump during the upgrade. Maybe you are so kind to provide an example how you have included Spamassassin in Exim, so that it will run with the packages of Debian 11? Is there a default configuration for a private virtual mail server on dynamic IP's ? Not that I am aware of. But if you roll yourself, you need to be able to take care of it. I think there might be solutions that might be better suited to your needs than Exim. Indeed i am thinking that maybe Postfix is a better choice as MTA, because Exim seems to be more and more complicated to configure? btw, this triggers me, as "virtual mail" does not have a definition, it leaves like ten way to interpret the task at hand. I would define an virtual mail system as email server for different domains, that can ideally be managed with entries in an database like Mariadb. Greetings karsten
