Roundcube filter with manage-sieve and IMAP server without SIEVE

[luckycgn]

Dear Forum,

I have a question regarding Roundcube, manage-sieve and an IMAP server without SIEVE.
I need filter rules and an autoresponder.

How would you solve this? Or is there a documented way?

So far I have researched that it is supposed to work.

My Roundcube runs on a webspace, the IMAP server belongs to my provider, so I have no admin access to the IMAP server.
I have researched that it should work with a separate root server, if a dovecot and fetchmail are running on the root server.
Is this the right way?

Many thanks in advance
Kind regards

Yes, this is possible.  But in this case you might as well go all in and make your own whole virtual domain mail server.
