Bugsy1966 Posted September 13, 2012 Posted September 13, 2012 Hi, I wonder if someone can cast some light on a problem I've recently encountered? I was in Vietnam recently and attempted to email a couple of hotels in Thailand. The first email I sent was returned as rejected by Spamcop - see '1' below for details. The second email (to a different hotel) went through fine and the hotel replied. However, when I tried replying to their reply, this was now bounced by Spamcop - see '2' below for details. This particularly surprised me as I was already in dialogue with the hotel. I did a bit of research (being unfamiliar with Spamcop) and came to the conclusion that the server my local hotel in Vietnam was using must be blacklisted so gave up as I knew I would be back in the UK the next day. I assumed as I would have a new IP then all would be well. So, here I am in London and I've just tried to resend the email from the ISP (SKY) and IP address I've been using for 2-3 years and it has been bounced again - see '3' below for details. Any ideas guys? I have read the various pinned topics but this seems outside of the scope of those that I have read.

Derek T Posted September 13, 2012 Posted September 13, 2012 Hi, I wonder if someone can cast some light on a problem I've recently encountered? I was in Vietnam recently and attempted to email a couple of hotels in Thailand. The first email I sent was returned as rejected by Spamcop - see '1' below for details. <big snip> First, SpamCop blocks/rejects NOTHING, see FAQs. It is the receiving server that rejects, based on a SpamCop listing. Second, the dirty outgoing server is a Yahoo server, nothing to do with the hotel. Does that help?
SpamCopAdmin Posted September 13, 2012 Posted September 13, 2012 Those rejection notices all have one thing is common... 77.238.189.90 = nm10-vm0.bullet.mail.ird.yahoo.com is sending spam to our systemd and has been placed on our blocking list of known spam sources. - Don D'Minion - SpamCop Admin - - Service[at]Admin.SpamCop.net - .

Thanks for pointing that out. It prompted me to try something else. As my original email went through ok (to seamespringhotel) I've just tried sending an email to them again by entering their email address in a new email (as opposed to hitting the reply button) and it appears to have gone through. I'm still a little mystified as to why it works this way - twice now - but when I hit reply to their email it does not. All a bit over my head I'm afraid!
InvisiBill Posted September 24, 2012 Posted September 24, 2012 Thanks for pointing that out. It prompted me to try something else.

I'm still a little mystified as to why it works this way - twice now - but when I hit reply to their email it does not. All a bit over my head I'm afraid! My guess is that it's coincidence. Yahoo has a lot of servers, and it's very possible that some of them are blacklisted at any given time (while their other servers aren't). You could send an email and have it go out one that happens to be blacklisted, and the next email could go out a different one that's not blacklisted. The way RBLs work is based on the IP address of the sending mail server. When you use a large shared email host like Yahoo, your "reputation" is based on everyone who's using that server. If someone else uses that same server (which could be chosen at random from a large pool of servers) to send spam, innocent users like yourself can be penalized like this. One of the downsides of free email services that anyone can sign up for is that they're abused by spammers. A hidden cost of this "free" email service is that your emails are more likely to be blocked because the free services are easy to abuse. One thing to keep in mind is what Derek said, SpamCop doesn't block anything. SpamCop makes a list of servers that have sent spam. The recipients have chosen to reject your mail as spam based on what SpamCop's list says about the server you used (despite SpamCop's advice that people NOT block email based solely on SpamCop's list).
