Hello,
in the last few days we have repeatedly had the problem that the MTA has sent the SMTP-Packets to our internal Exchange-Server without an IP-Address (0.0.0.0). We use version 19 (SFV4C6 / 19.0.0-B317) as VM in Hyper-V.
We can only solve the problem by restarting the service with the following command:
- service smtpd:stop -ds nosync
- service smtpd:start -ds nosync
However, restarting the firewall does not solve the problem.
Does anyone have an explanation for this? Unfortunately, as is so often the case, Sophos-Support was unable to help us.
Thanks!
