Blocking IP address 165.22.227.197

Posted January 3, 2020 2k views

We currently uses the ip address 165.22.227.197 for all of our customers emails.

I have looked and there doesnt appear to be any blacklisting on that ip address however whenever someone emails a sasktel.net email address from that specific ip the following message appears on a bounce back:

host mx1c11.megamailservers.com [69.49.101.234]
SMTP error from remote mail server after MAIL FROM:tperehudoff@sasktel.net:
550 5.0.0 We don’t accept mail from DO spammers<165.22.227>

Please advise on having that specific IP address removed from the block or if you have any suggestions on why we are being blocked by megamailservers.com

Thanks

  • Hi there,

    If that’s the case, I’d suggest reaching out to the folks over at sasktel.net or megamailservers.com and asking them to unblock the IP address that you’re sending emails from.

    Hope that helps!

Thanks Matt,

We have endlessly tried for the past couple of days. We were hoping you had some insight on getting it resolved.

  • Unfortunately not. Some providers simply do a range block against the whole of DigitalOcean due to bad actors using Droplets to spam before we can shut them down. We always encourage providers to only block IPs they’ve identified as spam, so that they don’t impact legitimate users like yourself.

    As said before though, this block is something they’re in control of, not something that we are, so there isn’t much we can do here really. Sorry!

I just ran into this issue as well. Emailed abuse@megamailservers.com to try and get my specific server’s IP white listed. Fingers crossed they do.

Greg,

We are still having the issue of emails being blocked. However we did hear back from them, with the response “we did not block the bank of ip addresses” but they said they have forwarded the email thread off to abuse3@megamailservers.com and mail@24hourwebhostingsupport.com to see if they have. You may want to try sending your email request off to those 2 email addresses as well.

Hey @thidev, I can see that this IP address is listed in 3 email blacklists i.e. dnsbl.spfbl.net, dbl.spamhaus.org, origin.asn.spameatingmonkey.net.

Reference: https://tools.pepipost.com/email-blacklist-checker/

Out of these, the first two sources are critical. There are a lot of mailbox providers who uses these sources as a trusted source to check the possible spam ips. You can get delisted from here. You can follow the delisting steps mentioned in the above reference link. You need to search for the domain and then you will get the steps for delisting.

**We ran a check from the following link http://multirbl.valli.org/lookup/165.22.227.197.html

And we have some blacklisted listings

spamgrouper@spamgrouper.to
197.227.22.165.netblockbl.spamgrouper.to

suomispam@suomispam.net
http://suomispam.net/
165.22.* 2019-06-17 digitalocean.com AS14061

https://darklist.de/removal.php

We have tried contacting these organizations to say that we have measures in place to prevent spam however this is the responses we are getting back:

*The listing can be removed if at some point in the future Digital Ocean
creates a functioning abuse team and starts to kick out spammers.
**

Is this something Digital Ocean has?

We have problems every month with our corporate emails being blocked due to spammers at DO. This is a major disruption to our business processes and reputation. There are currently 5 blacklists, and megamail is still blocking DO IPs, see

http://multirbl.valli.org/lookup/165.22.227.197.html AND

host mx1c12.megamailservers.com[69.49.101.248] said: 550 5.0.0 We don’t accept mail from DO spammers<159.203.18> (in reply to MAIL FROM command)

DO should be more proactive with abuse and customer service.

I have the same problem with my email server hosted on DigitalOcean. I have had this IP for over 6 years and it’s been kept off blacklists for that entire time. I implement SPF, DKIM, DMARC, etc. Megamailservers is the only entity that blocks my mail.

I have reached out to abuse@megamailservers.com several times over the past year, and never heard back. Has anyone else had any luck?

mail.craftmetrics.net is an alias for serv01.craftmetrics.net.
serv01.craftmetrics.net has address 198.199.107.94
serv01.craftmetrics.net has IPv6 address 2604:a880:1:20::184b:b001

5.0.0 We don’t accept mail from DO spammers<198.199.107> (in reply to MAIL
FROM command)

We’re also getting this -

550 5.0.0 We don’t accept mail from DO spammers<167.71.118> (in reply to
MAIL FROM command)

Seems like something DO needs to resolve of they’re just outright blocking any DO IP’s. Our IP is not on any spam blacklists anywhere. It affects a ton of our recipients.
