Is it possible to block users registration based on e-mail.

I want to block mails with the extension @mail.ru

I think you may look up in bb_func_checkusr.php file and edit the line which lists:

elseif(!eregi("^[0-9a-z]+([._-][0-9a-z_]+)*_?@[0-9a-z]+([._-][0-9a-z]+ )*[.][0-9a-z]{2}[0-9A-Z]?[0-9A-Z]?$", ${$dbUserSheme['user_email'][1]})) $correct=4;

so it would list something like...

elseif(!eregi("^[0-9a-z]+([._-][0-9a-z_]+)*_?@[0-9a-z]+([._-][0-9a-z]+ )*[.][0-9a-z]{2}[0-9A-Z]?[0-9A-Z]?$", ${$dbUserSheme['user_email'][1]}) OR substr_count(strtolower(${$dbUserSheme['user_email'][1]
}), 'mail.ru')>0 ) $correct=4;

Have not tested it but it should work...

Thanks, it works fine.

Sorry, but I have to try again. This time I need help to block everybody on there e-mail, unless they come form my own country. I tried by my self, but it didn't work out.

What is meant by "my own counry"? What domain zone is it like?..

Visitors can only be register when they have an e-mail address ending on .dk

Like hans@jubii.dk

OR substr_count(strtolower(${$dbUserSheme['user_email'][1]
}), '.dk')==0

is it really so difficult to imagine?.. ;-)

What if you have more than one domain you want to list? How would you write that?

You need to specify array list of all forbidden domains... for example, in bb_specials.php like

then the condition will be

then in bb_func_checkusr.php right before the starting if (!preg_match paste:

then instead of the condition supplied above it should be

OR $disallowedDomain

i.e.

hi,

anyone know how to modify software's core file, so that only certain emails are allowed for the registration. eg: xxx@ggmm.edu.com, xxx@ppkk.com

thanks in advance

Try to apply the solution above, but only change the final condition. From

to
And so in $forbidden_domains you need to specify the list of the allowed domains.

Hi Paul,
If I follow this thread correctly, your "block email addresses from certain domains" here is core destructive. If so, is there an alternative, non core-destructive way to block multiple domains (e.g., 126.com, tom.com)? Or is there a totally different approach I should consider?
With thanks,

I think there could be some way to create also a non-core-destructive solution... may be it could be even aligned with the forbidden phrases from the Anti-guest add-on which now I'm considering as the best tool against spam. But I can't provide this even this week - now I'm away from my working station and until the end of the week, unfortunately, I will not have time to check it out. May be the next week will bring more time, I'll keep your suggestion on hold, it needs to be thought out carefully before we do something...

I am all for non-core-destructive solutions! Thank you for considering my thoughts on this matter; and I shall look forward to being pleasantly surprised by the ultimate anti-spam solution you may develop later on. All the best.

Happy New Year to Paul and my fellow miniBBers.

For several months now, my miniBB has been bombarded with spam registrations from gmail.com, 163.com and tom.com addresses. A lot of the email addresses appear to be variations of the same base address; for example:
a.b.ck.e.yb.oy@gmail.com
ab.ck.e.y.bo.y@gmail.com
abc.k.e.yboy@gmail.com
The user names typically appear to be a random combination of letters and numbers; e.g., nS1lO0uB6z.

So far most of these spam users have been quiet (they do not post messages). I have been deleting the registations by hand, as I am not keen to see them fill up the database, clogging up the works.

Does any one else experience the same problem? Can anyone recommend any countermeasures?
