[Dovecot] procmail/formail --> Maildir

[Andre Huebner]

Hello,

thanks. I will test it in a few days. This week just holidays ;)

Sure, its just a modified example. Reason is to mark mails later graphical 
in a webmailer using some procmail/formail technics.

I think, if i activate the dovecot convert plugin nothig of my procmail must 
be changed. (just only the bugs ;)  ) Mails will be deliverd in mbox format 
to
/var/spool/mail/xxxxx
On Userlogin dovecot is picking up Mails and deliver them to maildir-inbox. 
Don't know if this is a very Feasible way, not really clean...

Thanks

André
