Twitter Mail Servers Marked For Spam
UPDATE: Twitter are in contact with SpamCop to resolve this issue. Meanwhile we whitelisted their servers on ours. Please make sure that you email address wasn’t flagged as inactive (and if it was, please follow the instructions below).
UPDATE 2: We updated the instructions on how to fix this, if your account was affected.
Today some of Twitter mail servers were marked as sending spam by SpamCop:
128.121.146.153 listed in bl.spamcop.net (127.0.0.2)
If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 14 hours.
Causes of listing
- System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)
- SpamCop users have reported system as a source of spam about 10 times in the past week
I’m not sure how this happened, but it is. This causes our servers to filter messages sent from the marked servers. We notified Twitter of this situation and we hope that they will address it soon.
But the problem is that besides that some messages will be lost, because of how Twitter mail system works, if it can’t deliver message to an address for a few times it marks it as non working and gives the user the following message:
If you received this message on your account, please do the following to make Twitter send you notifications again:
- Don’t panic :)
- Click on the link that says “click here to try sending messages to your email address again”.
- If this doesn’t help, please contact us by email - <help@topify.com>.
If SpamCop doesn’t whitelist Twitter soon, we will do it ourselves. But we keep this as a last resort option, so we won’t expose you to spam.
To keep updated on how this resolves, please follow us on Twitter - @topify, if you haven’t done so yet.
