Originally reported here -
OpenBSD's printf functions have a (mostly annoying but occasionally
useful) feature where they generate a syslog entry if printf %s format
is called with a null pointer.
It is tripped in lmtp/lda deliveries with 184.108.40.206:
lmtp: vfprintf %s NULL in "Cache %s: "
dovecot-lda: vfprintf %s NULL in "Cache %s: "
557 struct mail_cache *
558 mail_cache_open_or_create_path(struct mail_index *index, const char *path)
565 cache->filepath = i_strdup(path);
573 t_strdup_printf("Cache %s: ", cache->filepath);
Seems something is wrong to have this function called with no cache path?
