UPDATE TO ONGOING ISSUE
This problem is STILL ongoing and I really need to resolve asap: as per original post, the forum board activation email is rarely being received by new registrants.
I've recently reverted to the native phpBB php email settings (i.e. non-SMTP). I seem to remember when I set up the Board a few years ago that this was recommended in the Board set-up process for some reason, I think it was something about maximising the chances of a successful configuration (correct me if I'm wrong).
Now since I've done this, plus some changes to the DNS, I have had some limited success. Attempts to register from a GMail account leads to the activation email being received in the Inbox with 100% success (tested about 20 times). HOWEVER: every attempt to register using an Outlook/Live.co.uk account has a 100% FAILURE - the email doesn't even reach the Spam folder. Is there a known issue with regard to Microsoft/Outlook accounts?
I don't know whether this has any bearing, but the email address I'm using is one native to my hosting service, registered to my website. However, I then have these messages redirected to a dedicated Outlook account so that I get them instantly on my smartphone rather than having to log in to my hosting service mailboxes all the time.
So if I look at the Inbox of my hosting service mailbox (i.e. the messages before they are redirected to my Outlook account) I see Mail Delivery Failure - Returning Message To Sender messages. An extract of the content of these messages includes the following text:
Reporting-MTA: dns; mta-web1.extendcp.co.uk..... Action: failed..... Please contact your Internet service provider since part of their network is on our block list (S3150).
I'm assuming that the network in question is Microsoft's Outlook servers? My hosting service (Heart Internet) has recently started using Soverin as their mail provider partner.
So..... 100% success rate with activation emails sent to GMail accounts and 100% FAILURE rates with Microsoft's Outlook/Live Mail accounts. These are the only mail providers I can test because they are the only ones I have accounts for.
Any ideas folks? It's driving me crazy and I've sent innumerable messages to Heart's Customer Service team who have been unable to resolve.
