Cannot Receive Emails

Hello,

We are not able to receive emails, but are able to send.  It seems that we are blocking them from our end, but we have not turned on any type of SPAM filtering.

Here is the bounce back message:

Delivery to the following recipient failed permanently:

     106@ronrawlings.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain ronrawlings.com by mail.ronrawlings.com. [74.7.119.18].

The error that the other server returned was:
550 5.7.1 209.85.192.50 has been blocked by USPS Express Services

The strange thing is that I have no idea what is "has been blocked by USPS Express Services"  I have never seen that before.

Do you host your own mail server or is someone else hosting it?

If you are hosting the server and it is on your network, have you looked at you receive queue to see if any email is even reaching it?

Also, is internal email between users working?

Marcus BointonCommented:
That's a pretty standard bounce for being rejected by a spam filter.

It looks like the ronrawlings.com domain is using a blacklist (RBL) service that is listing google's IPs (which you sent from). That's not very helpful of them! I tried looking up that IP in current blacklists, and it's not shown as listed in any of them, but I've not seen a USPS one before.

Google's servers do occasionally get listed by the likes of spamcop, but delisting is dynamic and automatic and so it should fix itself.

Generally I'd say this is a recipient-end problem, not anything you've done. You could contact the domain owner.

We host our own email server.  The server is in our network.  other people have tried emailing us unsuccessfully.

We've never used a blacklist service.

We are able to send but not receive.

Looks like your domain or IP was blacklisted by the reputation service "USPS Express Services" per the 550 5.7.1 response.

I looked at your IP using DSNstuff Spam Database Lookup...

Blacklisting is something done by the receiver, not the sender. You may have your own server, but that email was sent via a google mail server, as the reverse lookup on Lee's comment shows.

I tried emailing myself (106@ronrawlings.com), from a yahoo account and it also bounced back with the same message.

If I remember it correctly earlier lots of Viruses used to be sent over the email which contains the subject "USPS Express Services". Are you sure there is no such rule on your server to reject the email which contains the text UPS/USPS anywhere in the email (header/subject/body).

squinky,

We are the receiver.  The strange thing is that we have not implemented any SPAM blocking and I am trying to figure out what's causing this.

74.7.119.18 IP came back clean from Spam Lookup Database.
The "USPS Express Services" is considered a virus/spam scam.

Marcus BointonCommented:
This is not anything to do with the phishing/virus emails claiming to be from USPS - these messages are plain bounces with no additional content, and they are occurring in response to sent messages, not being received spontaneously. What's more, what they are saying is true - the messages are being bounced.

Are you sure you have no spam software? The bounce does appear to come from your mail server (the google bounce says it's your IP that reported it) - check your logs for signs of the bounces.
