Email filtering with courierIMAP?

[Takashi Nishihama]

Hello,

I'm using courierIMAP server through Open-Xchange. Now I have a problem
with Email filtering. I can't set the email filter with the following error:

"Error in low level connection to sieve server (MAIL_FILTER-0014, 
749389421-1817)"

I know Sieve should be required to solve it, but I have no idea how I can
let it work with courierIMAP. Does anybody have an idea to use Sieve with
courierIMAP or to use OX Email filtering with courierIMAP in the other way?

Thanks,

Hi,

as far as i know, Courier does not have any SIEVE support. You might either switch the mailfilter plugin off (by uninstalling open-xchange-mailfilter) or use another IMAP Server (Dovecot, Cyrus...). Perhaps the Courier team can give you any answer about workarounds e.g. Note that OX requires remotely managed SIEVE which allows script modification through a network socket (2000/tcp).

Hi Martin,

Thank you for your answer. Now we are trying Cyrus as another solution.
Hope it works.

Cheers,
Takashi
