| Postini | Recent Filter | David S NY | 7/17/12 10:34 AM | My company provides CRM software where our clients can e-mail there contacts. The other day a client of mine had Fidelity's e-mail use of Postini temporarily flag our messages as spam. We actively monitor whether we are flagged as spam as it effe |
| Re: Postini | Recent Filter | David S NY | 7/17/12 11:25 AM | I should also mention the client indicated that Postini has temporarily blacklisted us as per there conversation with Postini. |
| Re: Postini | Recent Filter | FrankM TC/Reseller | 7/17/12 1:12 PM | Postini does not blacklist, but will greylist an IP for about an hour, if it triggers any one of 4 network filters. The Postini client can add your IP(s), to bypass these network filters. However, regular spam filtering would still apply, unless they |
| Re: Postini | Recent Filter | David S NY | 7/17/12 8:18 PM | Thanks Frank. In this case we host a solution for our client and one of their recipients had the email blocked because of the grey list. I always encourage SPF record use as past experience proves it does help. Do you think the lack of the SPF |

| Re: Postini | Recent Filter | FrankM TC/Reseller | 7/18/12 5:53 AM | No. SPF filtering is a different process within the network filtering component of Connection Manager. I would be concerned on why you triggered one or more of the 4 threat filters. Postini does not use RBL's, but its own historical data (since 1999) |
| Re: Postini | Recent Filter | David S NY | 7/18/12 7:26 AM | Hi Frank: Thanks for your continued interest on this. Basically I am changing the recipients e-mail to protect the innocent. When we further looked into the issue we were not blacklisted and a message we noticed the block but it was lifted later on |
| Re: Postini | Recent Filter | FrankM TC/Reseller | 7/18/12 8:09 AM | As I mentioned before, the error provided put your IP into a greylist mode, which usually lasts an hour, unless there is continued behavior triggering the filter. This greylisting is shared among all Postini clients in the time period the IP is block |
| Re: Postini | Recent Filter | David S NY | 7/18/12 8:45 AM | Frank thanks very much. the recipient has in fact done just that, at least on an interim basis. The more intriguing question which I am trying to understand better, is why (and I am guessing this may be related to the configuration mentioned) only t |
| Re: Postini | Recent Filter | David S NY | 7/18/12 8:52 AM | I guess it could also be possible FMR is the only recipient using Postini. But I do find it a little unlikely. |
| Re: Postini | Recent Filter | FrankM TC/Reseller | 7/18/12 9:39 AM | If the IP(s) or IP range is added as a bypass, then it will not trigger the filter, which is configurable by the Postini account. |
| Re: Postini | Recent Filter | David S NY | 7/23/12 7:13 AM | Frank, Is there anything further you can point out re: the triggers for Greylisting? My customer is quite concerned and I can't seem to contact Postini directly, since it isn't my account that had an issue it was my clients client. Dave |
