NFS Config vs Ceph / GlusterFS

2022-04-04 Thread dovecot 
Do all of the configuration considerations pertaining to using NFS on

https://doc.dovecot.org/configuration_manual/nfs/

equally apply to using something like Ceph / GlusterFS?


And if people wouldn't mind chiming in with which (NFS, Ceph & GlusterFS) they 
feel is better for maildir mail storage on dedicated non-container servers?
Which is better for robustness / stability?
Which is better for speed / performance?


Thank you.

Support of "extlists" in sieve filters

2022-04-04 Thread Marcin Bajer 
Hi all,

Don’t really know if this is sth. to post on this forum, but I tried
to make a sieve filter which tags mails from my contacts by the
category of the contact. Seems this feature is available in
Protonmail:

https://protonmail.com/support/knowledge-base/sieve-advanced-custom-filters/

require [“fileinto”, “extlists”];

Checks that the sender is in your personal address book

if header :list “from” “:addrbook:personal?label=Family”
{
fileinto “Known”;
}

Would it be possible to implement such feature also in dovecot?

BR,
Marcin
