Ms Exchange vs dovecot

[Marc Roos]

I was wondering about the sieve rules, because I thought they were 
executed during mail delivery in the lmtp process. You can also 'guess' 
this a bit from syntax of the rules or the single file they are stored 
in. Thus if you 'drag' messages between folders, they are not executed.


Off topic:
I know Exchange is a different solution. What I think is stupid, is that 
they store mail in a database still. Making it difficult to scale. (I 
wonder if they have such solution in their cloud) Better would be per 
user of course. I also do not like that they try and push users to their 
cloud with all this 365 advertising in the on premises solution. Sooner 
or later on premises will be gone.

Public folder is not removed, they were thinking of it, and community 
complained (afaik), so they kept it, still there in 2019. (although 
changed)

First of all, Exchange is a complete solution. Dovecot is a imap/pop3 
server ( a good one, sure... )

So replacing exchange means to find an integrated solution.

about the questions: public folder was removed in exchange. IMHO they 
made the right choice :)

There is a different thing, need different tools and different client 
app. You can create shared mailboxes ( i think it's a little demand for 
that, but yes)

Sieve rules should work ( never tried actually)

I can see a need for an integration with folders only when you work with 
webmail (like roundcube) . In this  scenario ( a liitle bit like gmail) 
is good to see the folders and attach them ( or save)

I use the kolab plugins for roundcube and there is a sort of integration 
between the chwala ( files plugin) and any webdav capable file server ( 
I use owncloud/nextcloud). So you can share files, edit etc using 
owncloud but also attach them and save them from webmail. You can find a 
lot of plugins in owncloud to deal with files, even editing with 
onlyoffice . IMHO, that's the way, there is no need to create a client 
app to deal with all; maybe other people will not agree but...
