MOD Validated/Released

Notes:
Great MOD so you don't have to enter in every different domain for a certain email provider.

It works great. Just wonder if it can be enhanced so that it can phpBB can handle subdomain.

E.g. *@*.abc.com will ban all email account including *@us.abc.com, *@uk.abc.com, etc.

Good idea. Didn't even think of that. My initial tests show this works...

Code: Select all

if (preg_match('#^(([a-z0-9&.-_+])|(\*))+@((\.([a-z0-9\-]+\.)*?[a-z]+)|(\*))?[a-z0-9\-\.]+((\.([a-z0-9\-]+\.)*?[a-z]+)|(\*))$#is', trim($email_list_temp[$i])))

My only concern, is that this effectively allows you to ban *@*.* , which is, well, the entire universe. But, I suppose there's no reason to prevent someone from banning the entire universe, as long as they understood what they were doing. Might be a good way to temporarily prevent any new subscriptions, if you had a need to.

Anyhow, let me know if that works for you, and I'll post an updated .mod file with the enhancement.

if you need to disable subscriptions/registrations, theres an option already for that in the ACP.

The only problem I have is that I can't seem to get adding *@*.blah.com to work. I have to add it manually, and from there it works wonderfully. 2.0.8a. subSilver.

Hi,

if I would add *@yahoo.* to the ban list, would this ban all currently registered users having a Yahoo mail address from the forum or will it just affect NEW user registrations (which would be what I want!).

thanks
Richey

What about being able to use the wildcard to block top-level domains.. such as all .coms (*@*.com) ??

Nice mod -- it's *almost* exactly what I was looking for! I was wanting to ban some stubborn .biz top-level-domains from registering their advertisements (visual confirmation had no effect on these guys). I suspect there are a number of people out there running forums who might sometime need to ban *@*.biz, *@*.ru, or other email top-level domains.

The mod as written above won't allow you to block *@*.whatever, so I modified the code as follows:

Code: Select all

if (preg_match('#^(([a-z0-9&.\-_+])|(\*))+@+(([a-z0-9\-\.])|(\*))+((\.([a-z0-9\-]+\.)*?[a-z]+)|(\*))$#is', trim($email_list_temp[$i])))

This will allow you to ban (for example):
*@anything.com
*@*.com
*@anything.*

Of course, be careful with what you're trying to ban, so you don't ban legitimate users.

I also added a "\" before hyphen in the first part of the expression -- as originally written, it wouldn't allow banning of usernames with hypens, but escaping the hypen fixes that problem.

Hope this is of use to someone,

Dave

Are you saying that using the code below actually doing *@*.*.* as in banning *@subdomain.domain.extension? or is this merely handling non-subdomains?

For example, If I want to ban all yahoo subdomain, I would want to enter this: *@*.yahoo.*, given this scenario, does the below code do that?

Thanks!

The link is dead or incorrect. Could someone please update the link or post a new URL to it? Thanks.

The link works fine for me. Make sure you don't have another program set to try to open .mod format files.

coderedstar · Post by **coderedstar** » Tue May 03, 2005 1:26 am

Hmm... almost every mod I wanted to use works. All except for this one and one other I tried to obtain a while ago. As well, I should have Dreamweaver set to open all .mod files into a writable format, so it should work, correct?

How about if I want to block certain words in an email address, like:

*phentermine*@*.*

How would I do that?

To Richey:
Banning users prevents them from logging in, so that would also affect exisiting users...
