I do understand, and the problem is that your question is similar to asking how to get a memory pointer from systemd for your program. The short answer is, not doable. The bit longer answer is that /usr/sbin/dovecot is a fancy service supervisor, it's job is to launch and manage processes, it

Hi! Sorry but that's just not possible, ther is no "core" where to create such object. There is no "dovecot" where to store things. When user logs in, dovecot executes /usr/libexec/dovecot/imap and transfers the connection fd there. then plugins and stuff are loaded, and the user does what he

No, I am not referring to that I want to create an object at first call in memory that object would be retrievable at second and furthers calls of the plugin, as long as dovecot is running On 2024-03-13 16:29, Aki Tuomi via dovecot wrote: Not really no. You should use e.g. dict inteface

Not really no. You should use e.g. dict inteface for storing this kind of stateful data. When deinit is called the calling core process will likely die too. Aki > On 13/03/2024 10:19 EET Joan Moreau wrote: > > > Keep a pointer in memory retrievable each time a plugin is called > > So the
