Thread: No subscription notification

What happened, in a nutshell (A big nutshell).......

Had 3 bounced emails from Bigpond overnight up until about 8:10 this morning. Started poking a stick at the problem at around 9:40 and all of a sudden began getting bounced emails from bigpond, around 50 of them bounce in, right up until 12:02 and that was the last one with the bad reputation message.

13:02 I began getting bounced emails again from Bigpond but they were all for non existent Bigpond users ie members who had either given bogus email addresses or had changer their address and not updated us with their new one.

From 13:02 to 22:15 I have received 187 bounced emails with around 70% of them coming from bigpond, most messages read the same as below:

SMTP error from remote mail server after RCPT TO:<[email protected]>: host extmail.bigpond.com [61.9.189.122]: 550 Invalid recipient:

By the end of today I will probably have had at least 400 bounced emails through my inbox and all for the same or similar reasons.

I assume some changes have been made to cause this.

No changes have been made.

We should never have been allocated an IP address that had been blacklisted for spamming, when we switched servers. That's a really bad start for us who had never spammed anyone and had a brilliant record and highest standing with Google and others.

Because of that we were put on a security watch for 3 months after the change over. We wiped the slate clean and were given a clean bill of health. However on March 10th some lowlife hijacked our visitor messages section of the forums and sent out well over half a million spam emails over a 7 hour period before I was able to shut him/her down.

This may have raised a red flag again. Also having so many members who don't have correct or updated addresses might also have helped towards this because they were bouncing/rejecting so many emails each and every day.

There are many things that could get us flagged, including something as petty as being reported as a spammer or spam site by a disgruntled ex member (got plenty of them) or some malicious bastard just out for a bit of fun.

There's a lot more going on behind the scenes than ever meats the eye in the open forums.

Anyway looks like this little lot is well and truly sorted for now and hopefully won't happen again..... Yeah right.

Thanks, Neil, for putting in the time and effort to follow through with this and for filling us in on the details.

I'm sure that while it was a bit of a nuisance to us, it was a royal PITA to you.

Glad it's sorted.
