    You have a great Sender Score of 98 / 100

    https://senderscore.org/lookup.php?lookup=119.30.33.249

    Try removing any links or sending from a different domain name. Do those emails get through?

    The recipients mail server might have your domain name blocked.

    There is also a very short TTL of 5 minutes (300 seconds) on your reverse DNS PTR record.

    ;; ANSWER SECTION:
    249.33.30.119.in-addr.arpa. 300 IN PTR mail.grameenphone.com.

    It's unrelated to this issue, but will keep you from landing on some picky RBL's if you increase it to at least 14400. I recommend 86400.

    Take "test" out of the subject line. It is quite common to use that as a trigger in MailWasher or SpamAssassin to detect spam.
