Good night, this command works fine and send the email when I remove the file attachment, but when i try to send the export file the log show stuck in "email: send ."
and the email never arrive to the inbox, this fail in just one router, i have many in the same networl and works fine.
thanks

it's so strange cause, without the attachment the email goes fine, the same script it's working in all other aps in the network, same RouterOS version, all it's the same config.

ok, i understand your advice, but just to clarify to you, this ap is behind a router like other 16 aps, all of them can send the email without problems, there's nothing blocking ping, in fact, i dont have nothing blocked in my network, so where i must change the mtu and how? also, i dont understand your comment about Steve..
thanks
