dovecot-lda panics when postmaster_address is given on command line

[Onno Molenkamp]

Hi,

When passing a postmaster_address to dovecot-lda on the command line
with -o, it panics:

$ ./dovecot-lda -o postmaster_address=anything

lda(onno,)Panic: file lda-settings.c: line 80 (lda_settings_check):
assertion failed: (set->postmaster_address[0] ==
SETTING_STRVAR_UNEXPANDED[0])

It looks like postmaster_address has already been expanded at that point
when it's given on the command line. (set->postmaster_address[0] is "1")

I'm running v2.2.15, but with v2.2.17.rc1 the same thing happens.

Regards,

Onno
