Emails not sending

[TeeBeeUK]

Has been fine all day until a couple of hours ago. Several emails sat in my outbox and getting error messages. It says too many recipents but it's only to one person. I have sent some emails earlier today (I send out a regular newsletter to a few people) but never had this problem before.

Is it a case of waiting? How long please?

The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for 'xxxxx', please contact your email service provider.

I'm sure we haven't made any changes, but in the interests of supporting you as best I can I've asked our email managers if they've made any changes.

Yes Ady. I'm aware but I haven't experienced any problems previously. I regularly do the same thing every 2 months and it's not happened before...just yesterday.

The sending limits have been in place for several years. They're in place to stop the spammers.

Hi TeeBeeUK 

Do you have a system for unsubscribing email addresses that fail delivery? People do often mark unwanted mail as spam or block receipt when they no longer want the mailshots. 

The general advice is to keep distribution lists small and for a large mailshot to spread out sending during the day. You should then be able to send to several hundreds of addresses of willing recipients without triggering the recipients per hour limiter TT501 error or recipients per day limiter TT502 error. 

If you use TalkTalk Mail webmail or an email client supporting TLS 1.2 connection security and the settings I've shown then your sending will be secure and fully authenticated. 

The most important recent change is to remove support for WLM in line with Government security requirements for a minimum connection security of TLS 1.2.

What's said in no doubt correct but I've been doing the same for a very long time so somethings changed recently as not experienced problems for a number of years. I send out bimonthly magazines and mailshots for a local charity.

Hi TeeBeeUK, Gondola's advice is absolutely spot on. Please let us know how you get on.

Hi TeeBeeUK 

The answer to how long to wait is at least 24 hours to get a full reset of the daily sending limit counter that's temporarily put a stop on sending.  But you may get a partial sending allowance back in the run up to the full reset so long as the TT502 error hasn't been triggered by Spam protection because some of your recipient addresses aren't deliverable or are not accepting mail. If that's happened then your sending may be rate limited to a very low level before the stop on sending is withdrawn in (usually) 24 hours after the last fail to send.

But the error message is directing you to get updated settings for your email client. Unfortunately that's not going to be possible because your email client Windows Live Mail (WLM) is so outdated it does not support the required secure email settings recommended by TalkTalk.

In the waiting time, is it possible for you to consider switching to TalkTalk Mail webmail or a supported email client that does support TLS 1.2 connection security? For example, Thunderbird if you're needing a free and up to date classic feel to email that's not too different from WLM.
