"too many emails from this sender( 2 )"

Posts: 2 · Posted: Thu May 24, 2007 7:13 pm

Hi All,

I am new to this forum, but a long-time customer of HostMySite. One of my customers using my email service reports a (new) bounce message "too many emails from this sender( 2 )". My service, and my customer have been in existence for years, and the customer has been sending emails on a monthly basis all that time. My service allows him to use his name/from address/reply to address, but this is definitely not a spam machine - it's actually pretty low volume (in comparison with what I read about).

Does anyone have any knowledge of how to eliminate this problem?

Thanks

Colin Goldberg

I've had this same problem,

Reason: Remote host said: 554 : Sender address rejected: too many emails from this sender( 2 )

and here's what Hostmysite responded. You should send a support ticket as well. Maybe it's a different issue for you.

There are many reasons why email delivery may be rejected by a remote recipient. Email travels over several networks to get to its final delivery destination, and there are a myriad of issues that can delay or prevent an email from being successfully delivered - from connectivity issues between provider networks, through to the volume of email, server issues, content management and blacklisting.

Since we do not regulate the content of emails sent by our customers, we cannot prevent any system from blacklisting or rejecting email from any particular customer, but what we can do is assist in the de-listing process.

However, your mail server's IP is not listed in any known internet blocklists which leads me to believe that the reason your mail is being rejected by the address your sending to, is due to a local system policy in effect on that particular server.

Failed Recipient: xxx@xxx.net
Reason: Remote host said: 554 : Sender address rejected: too many emails from this sender( 2 )

Unfortunately, since we do not control their email servers, there is little we can do to assist in whitelisting your email in this particular instance, so the best we can suggest is that you might want to contact postmaster@ and inquire as to why your email is being rejected, and how your domain can be either whitelisted or excepted from the list.

Thanks Jason,

I appreciate your reply and information. I will send it in to support.

This particular message is from our outbound servers. We have hard limits set on our outbound gateways to try and prevent service disruption. If you send out too much email the servers will start rejecting it. By too much I mean actually a lot, list sending a mailing list through the regular servers instead of list servers. Sending out that much email could cause problems for other customers. It is also another way to ensure spammers are not sending from our servers as when they start their scripts it usually will send out over this limit and we get reports daily that we can check to ensure its not spam.

Were they sending out a regular email or was it a mass email? We only have logs for about 3 days, due to the sheer abundance of the messages going through our outbound servers. If it keeps happening put a ticket into support with the subject ATTN: Ray Corbin and I can check into it for you.

I sent a large email list last week and got this error as well. I had the send stop every 150 emails and wait 61 seconds, so as not to put undue stress on the server. I have contacted support, and they suggested a list server for our sending this out. I am strongly considering this if the IP address is not the same as our web site's IP.

My question is, why did this happen now? The week before, I sent the same number of emails to a different segment of our customer base, and there was no problem. So what changed?

The only thing that I could think of was that there we were over our allocated disk space for that account. Can anyone else verify this?

Thanks,

M

I did a small test send to 100 addresses after I cleaned out the email account, and had a very high bounce rate. Obviously, not related to that.

There was a 'bug' in our outbound gateways that caused the rate limiting to not be in effect. This had apparently not worked for months and we had not noticed it. After noticing the issue we were able to have our vendor work on the issue and make corrections. This is most likely why you were able to send emails one time and not he next. Also the 'rate limiting' is a little more difficult then simple placing a maximum number of emails a domain can send before they are blocked. We have clustered outbound units, however the blocking is independent of each other for the rate limiting. Our servers are load balanced and operate independently so one server may block you and the other may not until you reach the maximum threshold for each server. Bulk 'canned' emails should not be sent through our shared servers as these servers are not optimized for bulk delivery and could result in problems for all of our customers. One of our list server options would be best suited for this type of email.
