deb repo with dovecot-antispam ?
by Håkon Alstadheim 02 May '16

02 May '16

There are .debs available for version 2.2 both from backports and ix.dovecot.fi, but neither seem to have the antispam plugin built for version 2.2. Anybody know why, and (if there is no particular reason) how to get dovecot-antispam in a proper .deb package for dovecot-2.2.* ?

issues with doveadm sieve commands
by Michael Grimm 30 Apr '16

30 Apr '16

Hi This is dovecot-pigeonhole 0.4.13 and dovecot 2.2.23 at FBSD 10.3-STABLE. I am used to run doveadm sieve commands for some time now whenever updating a sieve script. Recently those commands fail with a user set explicitly, e.g.: mail> doveadm sieve list -u test doveadm(root): Error: User doesn't exist When asking for all users, I do not run into any error: mail> doveadm sieve list -u '*' user1 default ACTIVE [snip] test default ACTIVE mail> doveadm sieve list -A user1 default ACTIVE [snip] test default ACTIVE That is true for all doveadm sieve commands, but other will work, like: mail> doveadm user -u test userdb: test user : test mail : mdbox:/—path-to-maildir--/test Hmm, any idea what is going on? I do not know when those commands stopped to work, I didn't try to update my sieve scripts for some time now. Thanks and regards, Michael

Password database extra fields and SQL
by Dave 29 Apr '16

29 Apr '16

Hi everyone, first post to the list, be gentle with me! Perhaps I'm missing something here, but it appears to me that many password database extra fields currently aren't much use inside SQL queries? All boolean fields like nologin/nodelay/nopassword are set if the column is present in the returned query, regardless of value (including NULL) For example, say you have a query like: password_query = SELECT hash AS password, NULLIF(active = 1, 'y') AS nologin FROM users WHERE name = '%u' Then nologin will always be set for this account, there's no realistic way to toggle the flag. Has anyone come across any workarounds for this problem that don't sacrifice efficiency by performing multiple lookups? I was considering what would happen if dovecot treated NULL fields as not present, but that immediately conflicts with advice to set password to NULL to satisfy the field requirement on nopassword. Any thoughts? -- Dave
