Bug #87825 for Mail-Sender: spaces prevent delivery of email; no warning raised

Dear Mail::Sender maintainer: First off, thanks for a great Module. We use it extensively. However, I did find a surprising "gotcha" recently: if the 'to' parameter is given an array ref, any element that contains a space will be ignored. Assuming that 'works@email.com','also_works@email.com', and 'skipped@email.com' are all valid emails: (1) ..., 'to' => 'works@email.com, also_works@email.com', ... (2) ..., 'to' => ['works@email.com',' skipped@email.com'], ... (3) ..., 'to' => ['works@email.com'], ... (4) ..., 'to' => [' skipped@email.com'], ... In these examples, 'works' and 'also_works' would receive their emails, but 'skipped' would not receive any emails due to the leading space. I encountered this issue when I took a working "to string" that contained whitespace and converted it into an array of elements by splitting on the comma. I thought to use the resulting arrayref in the to-field of Mail::Sender. Some recipients got their emails, but those that had a space did not. It looks like a change might be made to _prepare_addressess (line 1150) to remove whitespace from elements of the array ref or throw an error. Thanks for your time!
