My forum cannot receive Hotmail's mail recently

[TianJiao]

My forum cannot receive Hotmail's mail recently, I have not changed any settings.

Before, my forum can receive Hotmail's mail.
I don't know when it cannot receive Hotmail's mail, maybe a month ago.
Now, only cannot receive Hotmail's mail, but can receive mail such as Gmail.

Does anyone know what's the matter?

Thanks.

How does your forum "receive" mail?

[TianJiao]

I mean , for example

registration forums, can't receive registration letters by using Hotmail mails, but can receive registration letters by using Gmail mails.

or

notification set "Someone sends you a private message" by Email , hotmail can't be received now.

In that case I would suspect that the Hotmail server, or some other server in the link, is treating any mail emanating from a phpBB board as spam. This has been happening for years with some Hotmail servers.

My forum didn't receive Hotmail email until a month ago.
Until then, it had been able to receive Hotmail emails, including Hotmail spam.

it had been able to receive Hotmail emails

Then Hotmail have changed their spam filters. If all other users other than Hotmail users are receiving email then the problem is with Hotmail.

It is also highly possible that if you are on shared hosting someone else using the same IP address as you has been classed as a spammer and blacklisted.. If that is the case then you have two options - either get your host to move you to another server or take the issue up with Hotmail.

Have you checked your mail server IP address against the blacklists?

but i can send mail to hotmail's mailbox directly, only by intercepting hotmail mail from the forum.

This sounds like whomever provides the email handling for the hosting service where you are running phpBB has changed their policy, or detected some condition which is causing them to drop emails being sent by your phpBB hosting server that are directed at hotmail.com recipients.

What is the DNS name of your phpBB board?

What are the "Contact email address" and "From email address" set to in the "General" section of ACP -> General -> Client Communication -> Email Settings?

What is the "Use SMTP server for email" and "SMTP server address" set to in the "SMTP Settings" section of ACP -> General -> Client Communication -> Email Settings?

With this information, we should be able to tell who is currently providing your email handling; although ultimately you might have to talk to them to resolve the issue. Depending on what these are currently set to, there might be other suggestions as well.

It turned out that there was a problem with the database.
After restarting, mail could be received normally.

thanks for everyone!

Would you share what the problem was? That kind of knowledge is always useful for a Support Forum and could help those with similar problems in the future.

Maybe there's something wrong with the server's memory or the server has not been restarted for too long . I'm not sure.

Two days ago, I found that the forum often failed, so I restarted the database, and then it suddenly became better.

I use my own domain name's local email address.
acp->general->client communication->email settings->“smtp settings：no”

What do you mean by restarting the database?
