E-Mail Spam Filter

[Ardua]

This morning I complained to my local library staff about the lack of an e-mail to tell users that the County Library computer software was going to be updated over the weekend. I was told that an e-mail was sent out and that I should check my Spam filter. I have checked it and there is little in it other than e-mails from IDNetters replying to forum posts! I did get an e-mail from the Library Service on Thursday informing me that some books were due for renewal so I know that they have the correct e-mail address and it isn't being routinely blocked.

This is not the first time that I have not received e-mails sent out by the Council under a mass mailing. Perhaps, not surprisingly, when the issue is raised the response is that it must be a problem at my end. As I understand it, some e-mail systems are suspicious of mass mailings and they can temporarily isolate the sending account and delete what they believe is spam. Is there anything that the recipient (or not, as in my case) can do to educate the e-mail system?

Short of white-listing the sender, I'm not sure what else can be done, but others may have more of an idea.  Is this your local spam filter (the one within your mail client), or the IDNet one?

Have to admit, I've had some forum notification emails (for PMs) marked as spam, but not all, which is a bit odd.

Indeed, IDNet's spam filter seems somewhat random in nature but then so is the filter contained within my Outlook client.

I am using Apple Mail (no spam filter set) and IDNet. The issue seems to be restricted to senders who do not send out mass mailings on a regular basis. My limited research suggests that some e-mail systems treat unexpected mass mailings as spam and block distribution. I failed to find a solution. Generally, what I am not receiving is not that important; however, it can result in a 'we sent it, you deleted it' debate as it is impossible to prove a negative.
