@David W these examples are existent business partners which are contacted often a day or week. I don´t belive the bounce classification. Its so unprecise. just looked to anthoer customer who send an monthly newsletter to many receipients today i guess 50% are bounced back --Thomas

got an Bounce Back entiry in the HES Log when sending to gmx.de smtp;550 Requested action not taken: mailbox unavailable invalid DNS MX or A/AAAA resource record Could it be that 1und1 have problems to resolve the sending server aka domain.de.snwlhostedeu.com This confirms your post - something is wrong with DNS resolution…

@BWC glad to read your post ;-) on one customers server the MSX sendconnector could not resolve domain.de.outbound.snwlhostedeu.com so i added the 173.240.221.247 manually. Then sending out was possible for a while. But incomming emails are also inconsistent. --Thomas

@emaudlin the throughput depends on the cpu power. the NSA2600 is not made for the highspeed internet. The Value of 300MBps for dpi ssl connection is a good proportion to the throughput the NSA2600 is able to handle. Think about it, as you said before you have not activated any security options. What than is different to…
-
@emaudlin the NSA2600 speeds with no filters 1.9GBps in theory :-) but if you have only a few security options active it brakes down to 300MBps. A good value for orientation is the Full DPI throughput : here you are about 300MBps like you have. ----Firewall throughput 1.9 Gbps, IPS throughput 700 Mbps, Anti-malware…

@xtian on the button of the Screenshot there you find an Symbol like a wrench. Click to get the settings. Left Side choose connection profiles and clear the "not working" entries. i think the first entries are not reachable from WAN private ip adresses, the last one does not show the 4433 Port which came as default for a…
