Low reputation of the sending domain failure
Hello there,
My client cannot send emails to any gmail account. Automatically bounces with the message indicated above. Previously they had a virus that was sending spam, but this was already fixed. Likewise, they still can't send to gmail. It also affects other customers, since all their emails reach the spam folder.
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
mail@gmail.com
host gmail-smtp-in.l.google.com [64.233.180.26]

Is this your own server, or a shared one. If it's shared, It's possible that the poor reputation is from other users, and you may have little control over it. Check the domains and your server IP for blacklist entries on MXToolbox.com, and try to fix any that are listed. Enable DKIM, SPF and DMARK on the domain in question. These may help to improve the reputation. If the problems have been fixed already, then it could take Google a while to rebuild your reputation. 0 -
It is a shared server, where I have several clients. I have total control over the records, and all are correct. Nor is my IP blacklisted. How long does it take google to rebuild reputation? 0 -
How long is a piece of string ? Who knows, The goolge page I found just said "may take a short while" Do you share the server with other resellers, or is it your own dedicated server/VPS If your'e not sure then have a look at this page, pop your sever IP in the box, see how many domain names come back. 0 -
its my own dedicated server/VPS. Only 3 domain names return, but not the one with problems sending a gmail. Should all domains hosted on my server appear here? 0 -
When I run it against my IP, some of my domains don't show up either, so probably not. The idea was to see if it came back with tons of domains that you didn't recognise (ie other resellers). But you already confirmed that you have your own IP. I'm at a loss as what to suggest other than what I mentioned earlier. 0 -
Thank you, I had already read all that. I guess I'll have to wait 0 -
Unfortunately we have no way to control Gmail's blacklisting addition/removal process. You might make sure the domains you have are following the guidelines set here: How to Keep your Email Out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation Ultimately though, you might contact Gmail to see if they're able to provide you some insight. 0
