[Dovecot] BUG: messages created with permissions not respecting umask

Using dovecot 1.0rc15, together with postfix and dovecot-lda.

umask is set to 0007. This should ensure directories and files get created with read/write permissions for both user and group.

However, dovecot-lda writes files with 600 permissions, instead of 660. So dovecot does not seem to respect the umask configuration property for local mail delivery.

In my particular case, I have vmail:vmail own the mail directories, and a backup user part of the vmail group. However the backup user cannot read the mails and thus back them up properly.

Suggestions:

• respect the umask for file delivery as well
• alternatively, take the parent directory's permissions, strip executable bits, and apply to file

Thanks Thomas
