First of all, you must anchor the regex, because you match any address 
that has the domain at the beginning of the domain, e.g.:

somedomain.commer.edu
somedomain.com.tw

(the >? is actually a NOOP, because of the missing anchor).

I suggest

/.+\@somedomain\.com>?\z/i

\z is: Match only at end of string (and never a \n in the middle)

replace the .+ part with the localpart an quote dot etc. (see perldoc 
perlre)

e.g.:

/\A<?local\.part+\@somedomain\.com>?\z/i

Note the \A anchor at the beginning of the regex:

\A is: Match only at beginning of string
