Emails rejected

[strider57]

I cannto send emails from my outlook account and get this error message:

Server error: '453 4.1.1 bb96rKh7u8m2U Too Many Recipients (TT502)

It appears no matter how many recipients are addressed.

I can send emails from webmail, but it's inconvenient to have to keep logging in.

Is this a talk talk error or an outlook error?

Either way, any ideas how to resolve it?

Your mail should work normally now. We identified that a change made on our servers had only propogated to half of them so its now being updated.

Do you have a single O2 mobile broadband router for all home broadband connections to the Internet or use mobile data via each device sim and or dongle?

I feel it's likely that the TalkTalk system has detected multiple public IP addresses being connected (The O2 5G mobile service) and thinks that this is unusual so Spam Protection has rate limited the sending.

I'll request TalkTalk help to remove the rate limiting. We did have another customer using the Vodafone network that had a similar rate limiting issue and the team resolved that issue.

Yes, since talk talk stopped providing internet services for rural customers, I pay monthly to keep my email address. 

I use O2 5g mobile broadband and have done for some time now, with no problems at all. I cant access the internet any other way now that they are decommissioning the copper wire network - theres no chance of ever getting a fibre connection here.

Are you a TalkTalk MailPlus subscriber and if so which ISP network is providing your home broadband?

Sending from webmail is via the TalkTalk SMTP servers and if that sending is not restricted but sending from your home broadband connection is being limited by Spam Protection then that suggests the TalkTalk Mail system thinks there's something suspect about your public IP address.

I have a desktop, laptop and iPhone connected. My laptop uses mail for windows, which I understand is due to be made obsolete and I will have to change that to outlook. My phone uses an mail app. I have one email address with talk talk and do not use a VPN. I tried to send an email to 10 recipients last night and it rejected it with the above error. Since then I cannot send any emails at all from any of my devices, but I can use webmail.

TT502 is the TalkTalk Mail system telling you that your mailbox has been sending to too many recipients. Worst case is that the password has been compromised and unauthorised sending is taking place.

Or your use of TalkTalk Mail, perhaps using an overseas hosted VPN, has caused a lower limit to be set by Spam Protection for your sending and that's why you're easily exceeding the usual much higher limits. 

Tell us what devices you have connected to your mailbox and whether any have VPN software either standalone or as part of an Internet security package. We need to know more about how you use TalkTalk Mail to be able to disagnose the issue.  Are you a TalkTalk MailPlus subscriber and if so which ISP network is providing your home broadband?

[strider57]

That's bizarre. I send one or two emails a day and never to more than 10 recipients. 

I can still use webmail, so Im not clear as to whether its a talk talk or an outlook issue. 

If its talk talk, why am I paying for an email service that I can't use! If its outlook, why am I paying for office 365 when I cant use email!

The TT502 error means that your mail sending has been restricted because of too many outgoing recipients in the last 24 hours. It will take 24 hours for the full sending allowance to be restored. Normally you would be able to send to hundreds of recipients each day.

There are circumstances that can trigger a lower sending limit. Using mail via a non-UK network, a network where the IP address is a non-UK address or using a VPN where the VPN host is outside the UK.

Something about the way or rate your mailbox is sending messages has caused the spam protection process to kick into action.
