Hi,

I have just recently encoutered a funny prob with customer sending email to my email address domain.

Eg. Sender sends to me at abc@abcd.com from their GMAIL account. Gmail sends them a note saying ...

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 554 The IP Address of the sender
(64.233.166.179) was found in a DNS blacklist database and was therefore
refused.

Any idea what is wrong as the domain is a gmail domain and not mine and my customer is sending to me and not me sending to them. But when I try with my gmail I get that too but not when I try to send to my other personal email accounts.

I don't do any email marketing but it could be that my email sent out when my customers purchase or signs up.

Sounds like your mail server is configured to use blacklists to filter SPAM. Somehow, the IP address for that GMail server got added to the blacklist.
