[spameater] fix a pattern matching line
Created by: dingcycle
user <email@domain.com>
used to be split into
user
and email@domain.com
And the extra space next to the user was not stripped later on.
As a result, the computed From:
header became
user - email@domain.com <randominstring@erine.email>
, (note the two spaces).
This commit now excludes the space from the user
group pattern matching.
