Yes, but that is entirely up to the sending mailserver. If you do not receive a message that was initially greylisted and then subsequently whitelisted by hand (spamdb -a x.x.x.x) it is because the sending mailserver failed to re-send the message, not because spamd dropped it. spamd does not delete e-mail, it refuses to accept e-mail. Read spamdb(8); I cannot find immediate references, but I am pretty sure those log messages refer to the deletion of entries from the database. Also read the GREYTRAPPING section of spamd(8), spamd.alloweddomains may be of some use to you.
