Hi
our SMTP proxy (ASG 8.001) is blocking legitimate mail (for example from astaro.com) because of "RDNS missing":
---
H=(mx.astaro.com) [213.144.15.13]:51016 F= rejected RCPT : No RDNS entry for 213.144.15.13
---
>nslookup 213.144.15.13
Name: mx.astaro.com
Address: 213.144.15.13
---
H=(ns3.ticketcorner.com) [195.47.231.137]:60788 F= rejected RCPT : No RDNS entry for 195.47.231.137
---
C:\Dokumente und Einstellungen\dtschan>nslookup 195.47.231.137
Name: ns3.ticketcorner.com
Address: 195.47.231.137

I had to deactivate RDNS check completely to get these mails again. Our second SMTP proxy (ASG 7.506) doesn't show this false positives.
Anyone else seen this issue ?
