My e-mail is being blocked as spam!!!

By Network dude ·
I have a small office in China. Their web hosting and e-mail is being hosted by an ISP there. The local employees set everything up. Within the past 2 weeks I have been getting bounce back messages whenever I send e-mail to them. The bounce back error message is "553 Invalid Sender". Incoming e-mail to me and my e-mail server is redirected to an outside service first for spam filtering and then is forwarded to me. The MX record in my DNS information points to the outside service instead of to my SMTP server. I have been told by my Chinese contact that the bounce error messages are caused by a new anti-spam policy / process recently put in place by the Chinese ISP that marks e-mail as spam if the MX record in DNS doesn't point to where the e-mail originated from. It's practically impossible to communicate with the ISP directly because their support pages are in Chinese and nobody there speaks English. Is there anything I can do on my end to get around this problem?

Perhaps one of the local phone numbers at the following link will gain you access to a Chinese interpreter who will place a phone call to the ISP on your behalf. They can then interpret between you and the ISP while on the phone.

It appears that you understand the problem. the only way to effectively get past it is to either convince the Chinese ISP to allow your mail or make the MX record match. the second approach defeats the filter. The good news is you do not need a spam filtering "service" a spam filtering client called spambayes is very effective at eliminating spam. it is a bayesian filter that learns what spam is as you teach it by categorizing messages as spam or not spam. Now you can point your e-mail back to your smtp server, ditch the service charging you for something you can get for free and have your e-mail received by the intended recipient.
