Resolved: delayed outgoing email to Yahoo/Outlook/Hotmail
Further to Thursday’s post, here is an update on the situation with emails being delayed when sent to Yahoo, Outlook and Hotmail addresses.
As of today, Saturday 13 July, our tests indicate that there is no rate limiting or delays to mail sent from mail.coop’s servers to Yahoo or Microsoft (Outlook, Hotmail) addresses.
Our apologies to any users affected by these delays.
These delays were imposed by Microsoft and Yahoo on incoming email from mail.coop servers because one mail.coop account in particular had been used to send large amounts of spam. This was because the account had been hacked.
We are looking at ways to detect this type of problem more quickly.
