You don't want "contains", you want "matches".
"contains" does a literal string match; you want a regular expression
match.
A better regex is ^abc\d{10}@ because (a) it ensures abc is at
the start of the address and (b) it is less cumbersome. However, in a
filter you'll need to write ^abc\\d{10}@ because the string is
expanded.
And if you really want to match ABC (upper case) and not abc (lower
case) or aBc (mixed case), use "MATCHES" instead of "matches".
