coding in this way library only in local computer. it works well ..but remote run will not work..
how to send email.when I start strategy on remote server

If I am not mistaken, you cannot have another file (library in this case) on the remote platform, only the strategy file.
I am sure that there are topics on the forum where this question is asked (and answered properly), so make some research .

Place your mail.jar file in the strategy files' directory on your machine. To find this default directory on your machine use the method IContext.getFilesDir.
Use such annotation:

@Library("mail.jar")

You must not use the @RequiresFullAccess annotation.
