Found a customer email today which was rejected due to being listed in sorbs.

  Sorbs is a really strict but very reliable RBL. It's not uncommon for a major service provider like Gmail to become listed in one of the RBL's - they're commonly used to send spam and until the issue with the account/s sending spam is resolved, the intended behavior is to list them. Google has a pretty extensive range of IP addresses and it wouldn't be difficult for them to rotate them out when the issue is noticed. As far as the resend of the email, it's possible the user resent it, and also possible Gmail resent it when it received that notification, We'd have no way to tell you that though.

  I'll re-enable sorbs and monitor for a week or so until my confidence builds. Thanks

  @keat63 I've had a few people lately with issues with Gmail, I'd assume they had a rash of bad behaving accounts/hacked accounts which is what caused this.

  I decided to have another play with Sorbs today. Watching the exim reject log avidly, the first two emails which came though, and one I recognised as a customer, which was blocked by Sorbs. This customer uses live.co.uk which is part of Microsoft 'outbound.protection.outlook.com ' I immediately called the customer, who was already aware of the reject notification. Disabled Sorbs, and had him resend his email. I've no doubt Sorbs is good at what it does, but its way too strict for me.

  Hi, what I would do, (and I do), is to whitelist senders (rbl whitelist) like google (gmail.com), facebook.com etc. All other spamfilters etc. checks will perform before rbl checks anyways. Sorbs have had facebook, google, outlook/live/hotmail etc. on their blocklists, and will in the future too from time to time I guess. Just because they are BIG and send millions of emails, some rotten egg spamming from their servers should not keep your customers receiving emails from their servers. Just my 5 cents. Exim: whm -> service configuration -> exim configuration -> RBLs -> Whitelist at the bottom. And you can do this with postfix etc. too - Wallu

  I utilise about 5 other RBL's, all of which seem to work well together. Using sorbs was just another line of defence. However, if I have to start creating whitelists to allow the big ones through then i'm just creating more work. Nice idea though.

  Me too :)

  True that, but for me that's on my to-do list for every server I create. You only need to do it once. I just don't want to risk (not just because of Sorbs, but others too) that my clients don't get legit emails from these hosts, which they send millions each day. Not sure about the % or anything, but it is somewhat noticeable number of emails that come to my servers from these senders/hosts in question, so I just wanna be sure.

  Nice idea though.

  
  Thanks :) ... just an idea and no biggie really. - Wallu
