Cannot formulate regex

[Dotan Cohen]

I'd like to filter spam from a certain company. Here are examples of
strings found in their spam:
Mega Dik
Mega D1k
MegaDik
Mega. Dik
M eg ad ik
M E _G_A_D_ IK
M_E_G. ADI. K

I figured that this regex would match all but the second example, yet
it matches none:
|[^a-z]m[^a-z]e[^a-z]g[^a-z]a[^a-z]d[^a-z]i[^a-z]k[^a-z]|i

What would be the regex that matches "megadik" regardless of whatever
characters are sprinkled throughout?

Thanks in advance.

Or you could try using "MegaRegex"! I do and my girlfriend can't stop
talking about it! :)

m[^a-z]*e[^a-z]*g[^a-z]*a[^a-z]*d[^a-z]*i[^a-z]*k

FYI Kodos (http://kodos.sourceforge.net/) can be very useful for
developing, testing and debugging such regexes.

Thanks, it's even in the Ubuntu repos.

Liebnitz should have quoted Newton on that one, too!
