Hi. I'm using ISPConfig 220.127.116.11 with postfix and maildrop on a Ubuntu LTS Server production environment and I'm facing a LOT of problens concerning the email copy feature. Don't matter if I use "Send copy to" direct to the Destionation Email or if I "Send copy to" a Email Forward email, in both cases the same problens happens. First case: firstname.lastname@example.org <Send copy to> email@example.com What happens: 1- a@ reach it's quota limit 2- Everytime postfix try to delivery a email to a@, in the mail.log we will see "Permission denied maildrop: maildir over quota." 3- A copy of this email is sent over to b@ 4- Now b@ have a bunch of duplicated emails and they will keep coming till someone clean a@ inbox. There is a way to "fix" that? I mean, b@ should receive only a copy of the first attenpt or at least a copy of the delivered email, not the denied ones. Second case: firstname.lastname@example.org <Send copy to> email@example.com (Email forward one) firstname.lastname@example.org <Forward a copy to> email@example.com, firstname.lastname@example.org, email@example.com firstname.lastname@example.org <Send copy to> email@example.com firstname.lastname@example.org <Send copy to> email@example.com firstname.lastname@example.org <Send copy to> email@example.com What happens: 1- a@ got a new mail 2- A copy goes to cc.a@ 3- cc.a@ forwards a copy to b@, c@ and d@ 4- b@ send a copy to x@ 5- c@ send a copy to x@ 6- d@ send a copy to x@ 7- x@ got 3 new duplicated emails I believe that a copied email must stop in his first destination and not spread to the entire chain. The way postfix do when we add more destinations to the virtual file, like in: firstname.lastname@example.org usrA, usrB, usrC email@example.com usrB, usrX firstname.lastname@example.org usrC, usrX ... There is a way to "fix" that spread behavior of ispconfig? Thanks for any help.
