Limitation of "redirect to" filter?
« on: October 10, 2019, 11:41:13 PM »
Dear all,

the following problem in Roundcube 1.3.9 on an Ubuntu 18.04 (64-Bit) VS.

I do have a mailbox for an info@ account of an NGO.

Mails they arrive there will be filtered first for SPAM, INFECTED, and all other crap.. which will be deleted forever when detected.

After that, there is a filter which redirects all remaining mails to three different mail addresses... after that, the last task is to stop evaluating rules. So far so good.. it works fine.

But, when I add an additional redirect (4, 5, 6 or more) then the "redirect to"  is not working anymore and mails stuck in the info@ mailbox without getting redirected.

What is going wrong here? Is there a config file where the redirects can be extended? Any other advise how to possibly resolve that problem?

Could not resolve this issue yet and hope someone in here can point me in the right direction.

Thank you very much in advance for any help.

Ok, I found the solution.

The default value for Sieve-based Redirects is actually set to 4.

I have now created a /etc/dovecot/additional_custom.conf and set a limit of 25 and everything works as it should.

The content of the conf file is:

plugin {
   sieve_max_redirects = 25
}
