Good day.
This isn't really an EXIM problem but I'm not sure what to do.
I have a customer that can't send e-mails to two of his suppliers in
China in that his e-mails keep bouncing back with a '452 Invalid sender'
messages.
I tried sending an email to the postmaster there and it bounced back with:
> <postmaster@???>:
> 218.30.103.130 failed after I sent the message.
> Remote host said: 552 This user's disk quota exceeded, anyway you can send a smail (<1KB) message to inform the person. The email was way less than 1K.
I tried a telnet to mail.promexsh.com 25 and as soon as I did:
mail from: phil@???
I immediately got the 452 error.
This happens as well with the mail.jinmao.com server.
On further investigation I see mail.promexsh.com announces itself as
mxvip2.hichina.com (218.244.159.32) and mail.jinmao.com announces itself
as mxdxt3.hichina.com (218.244.143.23).
From the above I surmise that hichina.com has some serious problems or
am I totally out to lunch (ok, I may be right and still be out to lunch
but you know what I mean).
