Hi,
We have customers testing our next Zimbra release, which includes support
for postscreen. By default, postscreen is not set to take any actions.
However, one tester found that even with this being the case, connections
from their Barracuda Spam Firewall are being rejected thusly:
Mar 11 11:15:09 webmail postfix/postscreen[5234]: CONNECT from
[X.X.X.X]:38752 to [Y.Y.Y.Y]:25
Mar 11 11:15:09 webmail postfix/postscreen[5234]: PREGREET 36 after 0 from
[X.X.X.X]:38752: EHLO cabernet.example.com\r\n
Mar 11 11:15:10 webmail postfix/smtpd[5235]: connect from
cabernet.example.com[X.X.X.X]
Mar 11 11:15:10 webmail postfix/smtpd[5235]: lost connection after EHLO
from cabernet.example.com[X.X.X.X]
Mar 11 11:15:10 webmail postfix/smtpd[5235]: disconnect from
cabernet.example.com[X.X.X.X] ehlo=1 commands=1
Is this a known issue with Barracuda? Anyone have an idea how to work
around this? Clearly having their spam appliance be non-functional isn't a
great start. ;)
Thanks,
Quanah
