There seems to be a recent issue that has come up when gmail users are e-mailing into organizations using ASA-55xx firewalls. Has anyone had this problem and have any suggestions? These errors only occur with inbound messages originating from Gmail. Below is the message gmail users receive:
Technical details of permanent failure:
TEMP_FAILURE: Unspecified Error (SENT_MESSAGE): Connection timed out
Any help is greatly appreciated. Thank you.
