Why would one NOT want to use (favourite mta) + vpopmail?
You do know that exim can talk directly with MySQL, right ? And
since you can specify the SQL Queries, the database can have
any format, thus integrating with everything else ?
So does postfix. You are missing the point. vpopmail comes with all the
tools necessary. With postfix or exim, one would have to build their own.
Humm ? I never had to build any tools.
Oh? So account management was all manual via the sql command line?
I even have exim sharing the same table with radius (and currier-imap)
on one of my sites.
Ah, so you have courier-auth library too.
For courier-imap itself, of course. As far as I know, there is no other
way to make courier-imap work.
Yeah :D.
Having exim talking directly with spamassassin is also very good and
easy, and speed things up quite a bit.
Sure. spamassassin milter + postfix milter :P
Are we talking about exim or postfix ?
Both. You can get exim to talk directly to spamassassin and postfix
2.3.3's milter capability alows the same with spamassassin milter.
Using things like maildrop, vpopmail, amavis etc with exim is
just a good way to slow things down. The direct connection between
exim and everything else (spamassassin, antivirus etc) allows you
to reject mails during delivery, without the need to accept it
before passing to another agent.
??? postfix -> maildrop -> home dir/Maildir
Nothing in my system goes through vpopmail. vpopmail only creates the
Maildirs and maintains the mysql tables.
If you are using postfix, then it does make send to use vpopmail.
I'm not saying otherwise.
You do not have to use vpopmail with postfix. postfix can do just about
the same with its own virtual mail backend that supports SQL.
My point is only regarding Exim.
The thing is, many people don't realize that, when configuring exim
to use mysql, you write the SQL queries on the configuration file, so
you can pretty much do anything you want, even get data from multiple
tables. Also, you can put SQL lookups everywhere, even on the ACLs
(most specially on the ACLs), giving you a very good degree of flexibility.
Also, keeping everything happening inside exim, you make things much faster.
You don't have to keep forking new processes (which is costly for the OS),
and memory allocation is much smarter.
As I said, I don't have anything against vpopmail or maildrop. I'm just
against using those with Exim. If you are using something else (sendmail,
postfix, zmailer, qmail, whatever), you are very welcome to them.
The things that you have listed can all be done with postfix too. You
can have SQL lookups just about anywhere in postfix too. postfix has its
own virtual mail LDA that supports SQL and postfix can make use of that
database at the smtp level too. Back to vpopmail, direct use of vpopmail
tables will probably only be possible with exim and postfix.
So then, does exim provide user account management tools? Or is your sql
backend also the system account backend? If not, did you not have to
build tools to handle user account management or creation of user filter
recipes?
