<prompt> Human: So I vacated my previous apartment a month back and got my Final Account Statement Bill for 65 by mail. The payment options were check, e-check for which I need to fill an electronic payment pdf form and send back by fax or email or credit card 10 convenience fee. I elected to use the echeck form, so printed it out filled it, scanned it back, attached it to an email and sent it to the exact email address mentioned in the property website. But I got back an email with the following message: Delivery to the following recipient failed permanently: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain abcproperties.com by abcproperties.com. 12.34.567.89. The error that the other server returned was: 550-JunkMail rejected - mail-vk0-f50.google.com 123.45.678.90:34937 is in an 550 RBL, see vspf1 ip6:abcd:efgh:1234::48 -allSo, does this mean I can just not bother trying to get the payment to them after this? I theoretically tried in good faith to pay them, but they made it clear that I cant go to the apartment office itself and pay anymore, and given I tried the method they suggested to the T, am I still responsible to keep begging them to take my money? Their letter states if they dont receive the money by 30 days theyll hand it over to a collection agency. If that happens is this email proof sufficient evidence to tell them to fuck off? Or should I do anything more?  <response>: yes, you still owe the money.
