Every few month gmail and all tested other mail providers using port 465, 587 are blocked by my isp. Only E-Mails sent by ANRB.exe are affected. Mail sent by Thunderbird, Outlook and Co, which are all using these ports and same smtp server as in ANRB, are still coming through.
ANRB SW tries to establish link to mail provider but no data transfer comes through. Finally the link is terminated due to a timeout error. Therfore unfortunately AirNav Systems won't be able to help with this problem as the problem seems to be caused by the local ISP. Usually the problem has solved itself within a couple of days.
