INITIAL

Hotmail are not liking our outgoing email servers, and are bouncing email we try to send to them (even though we do lots of phishing/spam checking on outgoing mail).

We are trying to work out why they are not liking our servers, but are also configuring our servers to use a different IP address if you use authentication when sending email through our servers (smtp.aaisp.net.uk)

UPDATE

We've put in a work around and mail to Hotmail is being accepted.

We'll monitor this, and will also put in place other measures to help this from happening in the first place.

UPDATE

We're still seeing problems in relaying message to Hotmail as well as some other hosts (eg BT Internet/Yahoo).

We are working on this at a number of levels,

1. More tracking down and blocking of customers who are trying to send junk (typically customer with viruses sending spam/phishing email, and customer bouncing messages)
2. Giving our mail servers additional IP addresses to use (this will include IPs in the 81.187.30.x and 90.155.4.x blocks)

UPDATE

Email to Hotmail/Yahoo is currently being accepted. Mail is currently going out via B.painless using it's usual 81.187.30.52 IP. (Customers don't need to change anything, carry on using smtp.aaisp.net,uk as your smtp server). We've block and contacted some some customers who were sending junk messages.

We'll carry on monitoring this.
