So now I know I understood right in the beginning the X-Command: , but unfortunately it doesn't solve my problem with subscriptions ...
While sending mesaage to testing-request@ with
Subject: subscribe
and empty mesage body I get back:
[...] WARNING: Please make sure to start the Subject: of requests to the archive- server with the word archive. Unknown command subscribe. [...]
What shall I do?
Use the source and the usual debugging procedures. Smartlist thinks your subcribe request is an archive request. The code that does this is in rc.request when it calls "| arch_retrieve". Put VERBOSE=yes at the top of the file and analyze the logs after trying again. [ I would perhaps disable the X-command-allowed-in-the-body feature just to be sure it's not the cause for this behaviour ].
