Re: [Dovecot] expire tool - individual user/folder?
Hello, The patch shouldn't really have changed anything. in 1.1.16 it works without the patch. And I didn't fix anything in 1.1.16 either. Maybe it was some weird compiling issue or something.. i do not have an explanation, but effect is the same. i repackaged 1.1.15 with and without patch and only the one with the patch works. for 1.1.16 i do not need a patch. gcc is 4.1.2 but its not important for me, just some tests...

Re: [Dovecot] expire tool - individual user/folder?
This is what I meant actually, the name just changed in v1.2. What do you get with the attached patch? patch fixes the problem in both cases. it does not care if --enable-debug is enabled or disabled. in 1.1.16 it works without the patch. Thanks, Andre

This is what I meant actually, the name just changed in v1.2.

Re: [Dovecot] expire tool - individual user/folder?
Does the problem go away if you don't configure Dovecot with --enable-devel-checks? no, its not included in my configure-line. This is it: ./configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --mandir=/usr/share/man \ --with-ssl=openssl \ --with-storages=mbox,maildir,raw \ --with-pam \ --with-passwd \ --with-db \ --enable-debug i just added --enable-debug after having the segfaults whren running the expire-tool to see more lines... sorry for always making problems ;) Andre

Re: [Dovecot] expire tool - individual user/folder?
Hello, The plugin yes, but expire-tool not really. It would be possible to have userdb lookups return an overridden expire setting and use it instead of the global one, but that would require writing more code.. i have made 2 testsetups with expire-plugin (mysql,dbd) it seems to work, in table i can find new entry for expire_stamp But how i can make individual settings for different users? adding user/folder in dovecot.conf gets ignored. is the plan to add separat settings directly in the expire-dict? (adding lines in mysql-table?) second question is much more importend. how to debug this if i get seg.faults when running "dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test" ? basically connect to mysql/dbd is working. if is expire-timestamp in future i get correct results. problem occurs when a folder is expired and action is required. how can i debug this to find real error? Common debugsettings in dovecot.conf seems not to work. i did compile with --enable-debug but all i got is: # dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test Warning: Growing pool 'Expire pool' with: 1024 Segmentation Fault Thanks, Andre

[Dovecot] expire tool - individual user/folder?
Hello, is the expire plugin usable to delete mails with different settings for each individual user? If i view sample config at http://wiki.dovecot.org/Plugins/Expire it looks like expire-data are related to foldernames. Is it possible to let each user "activate" the expire-plugin for different folders with different settings? Thanks, Andre
