.*![a-z][0-9][0-9][0-9][0-9].*@.*:.*
.*![a-z][a-z][a-z][a-z][0-9][0-9][0-9][0-9].*@.*:.*
well yes that would work.
But you probably would want to have fun with the repeat thingy, so:

Code: Select all

.*![a-z][0-9]{4}.*@.*:.*
and actually.. if the ident is just 1 letter + 4 digits and nothing more.. then you probably do not want a .* there, so:

Code: Select all

.*![a-z][0-9]{4}@.*:.*
or what I would use (^ means start at the beginning, .+ means match 1 or more)..

Code: Select all

^.+![a-z][0-9]{4}@.+:.+
(similar stuff for other regex)

Why use two regexes?

^.+![a-z]([a-z]{3})?[0-9]{4}@.+:.+$

ofc, i could be wrong... but should that be:
^.+![a-z]([a-z]{4})?[0-9]{4}@.+:.+$

(1/4 letters, 1/4 numbers)
remembering that im just starting out with regexs :P
