Yahoo Outbound Mail Servers Blacklisted by Hotmail?

New Email
The non-profit organization I volunteer for is noticing emails that are being returned due to what looks to me like our domain and/or ip address being blacklisted. From testing it seems to be intermittent as some emails get through. Thus I believe the blacklisting is occurring because of the ip address rather than the domain.

Our email service provider is Yahoo Small Business. If the blacklisting is occuring at the ip address level then do I have a legitimate concern that this is going to be a ongoing issue for us considering Yahoo Small Business has outgoing mail servers that they also share with their free yahoo email accounts.

Feedback from individuals with more experience than me (I have none!) in dealing with these issues would very much be appreciated.

Re: Yahoo Outbound Mail Servers Blacklisted?

Hello,

What is the exact error message that you are getting from the Yahoo mail servers?

How many emails are you trying to send at one time?

Can you slow down how fast you are sending emails to Yahoo?

Have you checked your email queues to make sure there is not a problem on your network generating an unexpectedly high amount of email to Yahoo ?

Re: Yahoo Outbound Mail Servers Blacklisted?

Or do I have this backwards?

Are you sending from Yahoo and getting error messages from other mail servers?

Same first question, what is the exact error message that you are getting?

Reply with the full error here and we can further help you to identify the problem.

Re: Yahoo Outbound Mail Servers Blacklisted?

Backwords... problem is with sending emails from a Yahoo hosted Small Business email account.

Below is an example of a failure notice received when trying to send an email from our domain (4luvofdog.com) to a hotmail addresss. Some emails get do get thru to hotmail addresses. When I test with my own account I would say that 25% of my attempts fail while others are successful.

I have contacted MSN and "they are looking into it". Yahoo Support has been of absolute no help.

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Re: Yahoo Outbound Mail Servers Blacklisted?

Interesting. You'd think that Hotmail and Yahoo would be able to work this one out and know about each others mail servers. It is public information after all. I'll open a ticket on the Yahoo side of it and see what they say about the error above.

Re: Yahoo Outbound Mail Servers Blacklisted?

I tried dealing with Yahoo Customer Support but got no where. They didn't seem to care at all that their mail servers are potentially blacklisted and that it was affecting a paying Yahoo Small Business customer and that it may also be affecting other customers. When I asked the customer service rep if he could tell me from the email failure message what was the ip address of the outbound mail server. He said.... "It's right there ...65.55.92.184 ". Well, unless I'm the idiot, I believe that is the hotmail receiving mail server. I obviously didn't think he was going to provide me any further help so gave up.

I know enough to know that I don't know enough about these types of problems. So any help I can get in regards to what I need to do to resolve this is very much appreciated.

Note this isn't just a problem with sending to hotmail. We are also having other domain mail servers reject our emails. Ugh!

Re: Yahoo Outbound Mail Servers Blacklisted?

Do you have any mailing list newsletters sending through Yahoo or just regular business emails?

Re: Yahoo Outbound Mail Servers Blacklisted?

We are a dog rescue organization. Most emails sent are just individual emails sent to applicants who apply to adopt dogs. A couple of times a month though the foster home coordinator does send out a mass email to our 40 foster homes. I have also been made aware that our volunteer coordinator is also sending out mass emails to our volunteer list (not sure how many recipients yet). Emails are only going out to individuals that have offered to assist our organization.

I know that I should get the gals doing the mass foster home and volunteer emails to change to use some sort of mail list service. But this is easier said than done. Would you recommend I get them to change.. and do you recommend any mail list services? I know Yahoo has their YahooGroups service but would that run into the same issue of yahoo mail server ip addresses being blacklisted.

We are utilizing MailChimp's email marketing services for sending out a quarterly newsletter to a 400+ mail list.

Re: Yahoo Outbound Mail Servers Blacklisted?

MailChimp is a service that a lot of people like for their mailing lists.

I'd stick with sending your email lists direct from yourself or a dedicated mailing list service.

You may also be able to send them out your ISP's smtp relays.

Hello,

My contact at Yahoo replied and said they they put in a request to Microsoft to get a few of their IP's unblocked.

Hopefully the situation will improve for you over the next few days.

Raymond, I sincerely appreciate your assistance with this. You are the first contact I have made that has given me any help. Thanks!

Unfortunately, this situation has not improved but has gotten worse. We are now having all sorts of receiving mail servers (not just msn hotmail) refuse our emails due to "reputation" problems of the outbound mail server's ipaddress.

We need to find a new email hosting provider. Unfortunately we cannot afford our own dedicated ip address for hosting. Ugh!

Hello,

It's too bad that things are getting worse. Maybe there is another business sharing your IP address that is causing the problem. If you want you can send a text email from your Yahoo to {address removed} and I can try to find out who/what is causing the problem coming from your IP address.

Have you considered trying MailChimp or AWeber for your mailing lists?

Raymond, I have just sent an email to the {address removed} account.

At this point our organization is looking at utilizing MailChimp for our mailing lists. It is a free service as long as the recipient list is below 500 and less than 3000 emails per month are mailed out. This will fit our needs. As a non-profit dog rescue, we have very little funding available for things other than caring for the immediate needs of the dogs in our program.

Again, thank you for your help.

The Yahoo IP 67.195.14.56 for your email is on at least two RBLs. The failed RBL's are the Barracuda BRBL and the Lashback RBL.

I am not a fan of the Barracuda RBL because they link to a 3rd party that is owned by the same parent company as themselves and they require payment to get off their list. That seems a little shady and in their best interests not the best interests of the internet to me.

The lashback RBL is for mail servers that are sending email to email addresses that could not ever have possibly subscribed to mailing lists but exist on lists. They may have been picked up from web page harvesting, sold by other spammers, etc. This is the first time I've seen someone on their RBL.

Between the RBL's above and not being able to send to Hotmail at this point I'd say find a new email host and replace your Yahoo service, or keep the Yahoo and continue to use Mail Chimp if that works for you.

How has the Mail Chimp service worked for you? On the surface that appears to be a great alternative for small businesses and not for profits that have small mailing lists and are having trouble sending out the ISP's smtp relays. Would you consider writing a short email review of their mail service and let people know what you like and dislike about the service?
