I have a customer who is a large corporation and lately my emails to them a re not being delivered. I get messages that say ...
host alt4.aspmx.l.google.com [108.177.96.27] SMTP error from remote mail server after RCPT TO:: 450-4.2.1 The user you are trying to contact is receiving mail at a rat e that 450-4.2.1 prevents additional messages from being delivered. Please res end your 450-4.2.1 message at a later time. If the user is able to receive mail at that 450-4.2.1 time, your message will be delivered. For more information, p lease 450-4.2.1 visit 450 4.2.1
I contacted my hosting provider who provides email service to me and they s ay they can't get anymore info than what is in the bounce message. I need to contact the customer. I don't think that is going to go very far. They are a large multi-national organization speaking English as a second langu age and similar issues tend to get a loud, "Huh?"
The strange thing is that the message comes from Google, so I'm guessing th ey are using Google for their email service. I guess that's not an impract ical solution. I can't say I fully understand the issue. My hosting provi der says it isn't our end that has the problem and of course I can send ema il to other recipients. Likewise I can send email to this customer from we b based accounts like Yahoo mail. They don't seem to be aware of the probl em, so I'm guessing I'm the only one affected like this.
Is anyone here familiar with sort of message and what could cause it? I no t only get it once, I've gotten this every day since Thursday for every ema il I've attempted to send to them. My provider says the errors are permane nt which means they don't retry to send the message, but how else would I g et multiple bounce replies? I need to ask them that.
