======VPOP3.MessageSeek=====
The [[lua_scripting|Lua]] function 'VPOP3.MessageSeek' sets an internal read pointer to the specified location of the message being processed

This function is only available in the **ProcessMessage** function of the [[lua POP3 client script|POP3CLT.LUA]] or [[lua SMTP server script|SMTPSVR.LUA]] scripts.

It takes one parameter:

The function returns one value:
