[Solved] Email Smtp Sending Limit Per Hour?

[mjwu1008]

Hello Helio,

For a few days now, I have been getting “Mail delivery failed” messages. I have done some tests, and from what I have seen, I am now allowed to send only one email per hour? Is this correct? This limit was not there before as far as I know.

I’ve forwarded a copy of one of the failure messages below.

Please let me know if this limit is normal, or if it can be lifted/corrected. It is inconvenient.

I believe the system automatically sets this limit when an account sends too many emails. Our normal limit is 50 per day (regardless of origin or destination, so for instance sending to a large mailing list through our service could easily wipe out your quota for the day).

 

Krydos can explain more and restore the normal limit for you. Escalating.

[Krydos]

Well, there's not much for me to add. As Wolstech already said you exceeded our recommended daily sent email limit without asking us first for permission to send emails above the standard limit and the system automatically throttled you down for being a possible spammer.

[mjwu1008]

Actually, I think there is a mistake. I don't think we exceeded the limit of 50 in one day. We do not send a lot of emails.

 

However I did make a request to Verizon Online to whitelist us because their anti-spam was blocking my sending to a colleague (see forwarded msg below). They wrote me back and said that the problem should be resolved within 72 hours and afterwards this limit started kicking in.

Maybe that Verizon interaction caused the problem? It seems to coincide in timing.

 

In any case, could I be reinstated to 50 per day rather than 1 or 2 per hour?

I have no intention to exceed 50 per day, and if ever I need to I will make sure to ask you first for permission.

 

If it helps, here are the emails with Verizon:

I have no intention to exceed 50 per day, and if ever I need to I will make sure to ask you first for permission.

In the last ~10 hours your account has attempted to send 32 emails.

[mjwu1008]

The 32 emails are probably including all the tests emails that I did to try and isolate and identify the problem on my end before resorting to contacting you, as I have no wish to bother you unnecessarily. I sent many emails to our personal divineliving.org addresses as well as my personal external yahoo and gmail addresses in order to examine the results.

 

If you look over the long term of our usage, over several months, I think that you will find in general we send an average of much less then 50 emails per day, maybe 10 per day, possibly less, but I am not totally sure. I just know that we do not have any regular mailing lists/bulk mails, and we do not send emails every day, sometimes not for several days.

 

Is there anything I can do to make amends for whatever fault I may have committed (maybe by contacting Verizon to whitelist our divineliving.org emails sent from IP 65.19.143.2) so that we may be reinstated to 50 per day?

 

I do appreciate your service and your volunteer work, and am sorry for any trouble caused to you.

If it helps for your information, we are a small 501©(3) non-profit trying to do our small part, make our small contribution in our way.

 

Thanks for any clarification you can offer on how we could change our behavior and actions in order to continue to receive the gift of your free web-hosting service.

In the last ~24 hours your site has now attempted to send 59 emails.

 

The reason I let you know how many emails your site had sent was to make sure you were actually sending all those emails. Sometimes people get throttled because their site sends and email for each account creation and bots are creating hundreds of accounts per day. If something like that is happening on your account it would be best to get it under control prior to having the standard email sending limit reinstated because you would run the risk of just getting throttled again immediately. Since you're certain you're going to be able to keep your account under the recommended 50 emails or less per day I have gone ahead and reset the email limit for you. Let us know if you need any further assistance.

[mjwu1008]

Thanks for the info and advice.

 

If I understand correctly regarding the bots and the account creation to which you referred, we have no facility on our website for people to create accounts.

 

However, we have an idea as to what the problem might be, and would like to know your opinion.

 

We did not try to send ONE SINGLE email in the time between your msg where you wrote "In the last ~10 hours your account has attempted to send 32 emails" until your last reply where you wrote "In the last ~24 hours your site has now attempted to send 59 emails",...

so where are these additional 27 emails (59 - 32 = 27) coming from?!

 

Could it be junk mail hitting our autoresponders for email addresses that are no longer active? Therefore we would not see the messages come in to our inbox, but nevertheless an autoresponder would be sent from our website.

 

We think this could be the problem, so we have just deleted all of our autoresponders for inactive email addresses. Hopefully, you will see a reduction in emails being sent from our website.

 

We had shut down some email addresses because they were being hit by junk mail lists, but we left an autoresponder for those legitimate persons who might try to contact an address they had for us from the past, informing them how they could get a valid email address for us.

 

Do you think our assessment regarding the autoresponders being the cause of activity could be valid?

 

If not, do you have any other ideas? Could someone be hijacking our site?

[wolstech]

Definitely. The auto-replies count toward the limit like every other email.

 

Do you have a contact form on your site that sends an email when submitted? I've seen these get botted and cause this as well. If so, consider adding a captcha to deal with the bots.

[mjwu1008]

No contact form on our site.

To give our email address and to avoid getting picked up by bots, etc., we just display a jpeg image (not actual text that can be copied and pasted) that says something like "contactus at divineliving dot org" so that a human has to turn it into an actual working email address. Is that a good idea?

 

Also, now that we have deleted the autoresponders, emails sent to inactive email addresses on our domain, whether junk or from real people, will still receive a "Mail delivery failed: returning message to sender" message sent from "Mailer-Daemon@stevie.heliohost.org" .

 

Do these count toward the 50 limit?

I assume not because they are not coming from our domain name, but from "Mailer-Daemon@stevie.heliohost.org" .

[mjwu1008]

Hi again,

 

Now that we have deleted the autoresponders, it would be useful for us to know, and if it is not too much trouble for you to tell us:

 

How many emails has our site/account attempted to send in the last ~24 hours?

 

We have not tried to send ONE SINGLE email during this time.

 

Thanks
