    It's an interesting new tool and Link2ICT are right, it should in theory reduce the volume of spam over time. Unfortunately however it will cause massive disruption for users - presumably just users on Zimbra when sending/receiving mail and not Office 365 when using OWA?

    One user has commented that their internal e-mails to colleagues are delayed... yet you'd think all school domains in Birmingham would be whitelisted?

    Still have lots of users complaining about delayed emails.

    Re-reading the KB article, it states:

    Most legitimate mail servers will wait between one to four hours and try again
    I wonder what percentage most represents? As we have users waiting 12 hrs and still not receiving the email they expect.

    Also:
    Grey listing occurs when a external mail server tries to send mail to our mail servers, and this mail server has not sent mail to our mail servers before. The sending mail server is told that at the current time our mail server cannot service the request and to try again later.
    So when an e-mail is sent from an external source (for the first time), what actually happens to it? It's grey listed Link2ICT's end, but as far as I'm concerned it's sent my end. Why would any mail server re-send the same e-mail? I'm failing to understand how this concept works and clearly it's not just me.

    or in our case it's sent 2 days later it rebounds, resent rebounds, resent and rebounds only to be told the address isn;t valid by Link2ICT server.... I've got no idea what the grey listing involves but it's causing a huge head ache here.

    I sent it at 13:18, so if you've not long received it - that's approx. 7 hours waiting time from Office 365. Blimey!

    So clearly it's sort of working, but I've just sent @Little-Miss a test e-mail at 20:34. Did you get it pretty much instantly?

    So it took 16 minutes to get from Office 365 to Zimbra, despite it being the second e-mail... interesting. Surely, surely it shouldn't take any more than 30-60 seconds max for any e-mail to arrive at its destination (taking into consideration everything's setup correctly and working)!

    Might be worth Link2ICT taking note of this example, considering it's out of hours. E-mail flows should be relatively low.

    On a related note, you'll shortly receive the new costings from Link2ICT for numerous services, but I've noticed on page 1 that the agreement is for three years when previously it was for one year.

    Obviously this has big implications if your school decide to change various parts of your service away from Link2ICT now or in the future due to this new agreement.

    I feel an argument brewing within (not that I need an excuse to have an argument)! My paperwork still hasn't come through but you would imagine that the scenario @Michael paints it the reason for them trying to lock schools in. Out of interest Michael has there been much of a reduction over last years costs?

    Yes and no. The 10Mbps link is priced based on pupil numbers, but generally speaking, everything else has gone up slightly. 100Mbps is the same for any Primary.
