[SM-PLUGINS] avelsieve & Apple MacOSX Tiger Mail Server ( was: Re: [SM-PLUGINS] Development Request )

I'm following up on Squirrelmail-plugins, if you wouldn't mind.

Sieve is somewhat broken in 10.4.

Now, I don't expect you to fix the problem, of course... That's
something different entirely.

A work around has been discussed, which seems to work.

>From what I understand, in OSX the Sieve functionality is there, because
underneath it all there is a Cyrus, but there is no timsieved, daemon
which listens for upload/download/management of scripts. So the OSX
people do these hacks/workarounds and in the end find out it works
perfectly.

I've had similar requests about Exim filters, which also do not have
transport mechanism.

You could probably give me some time to design wrappers and abstraction
layers for different backends - MANAGESIEVE (timsieved, existing),
fopen()/fwrite(), FTP or whatever.

When I do, I will let the OSX people hack their own backend.

I'll be away for two days, and when I come back I will try to sort this
out.

BTW, I had this correspondence from before about OSX. They provide
information about OSX quirks.

avelsieve on Mac OS X (Tiger) Server



Alexandros,

        I've been unable to use avelsieve under Mac OS X 10.4.1 
Server. 
<http://www.afp548.com/article.php?story=2005051020271724&query=sieve> 
implies this is because Apple's timsieved doesn't advertise the 
authentications it supports. SquirrelMail's configtest.php confirms 
what I've set in Server Admin, which is "AUTH=PLAIN AUTH=LOGIN 
AUTH=CRAM-MD5", so I think if avelsieve supported a "force 
authentication" option we might be okay, until Apple fixes it on 
their end.

        Interestingly, I see avelsieve.mo & avelsieve.po files in 
Apple's SquirrelMail installation, but not avelsieve itself. They 
also have a bunch of sieve man pages without the described programs. 
Hopefully they'll fix this soon.
