Hello,
we ported our firewall-system from v6.305 to v7.005. it seems all okay
since we look in the pop3-proxy-log. we have the following configuration:
Internal POP3-Server: 10.10.1.100
External POP3-Address: 62.8.xyz.xyz
DNAT-Rule: Any->POP3->62.8.xyz.xyz -->Dest->10.10.1.100
POP3-Proxy: Allowed Networks=Any
Paket-Filter: Any->POP3->10.10.1.100 Allow
Pop3-Proxy-Log:
2007:06:27-00:26:33 (none) pop3proxy[29167]: id="1117" severity="error" sys="SecureMail" sub="pop3" name="Error" info="communication error with cffd" message="basic_ios::clear"
2007:06:27-00:26:33 (none) pop3proxy[29167]: id="1117" severity="error" sys="SecureMail" sub="pop3" name="Error" info="communication error with cffd" message="basic_ios::clear"

2007:06:27-01:34:55 (none) pop3proxy[25554]: id="110Q" severity="error" sys="SecureMail" sub="pop3" name="Connection error." message="Unknown connection error" serverip="62.8.xyz.xyz" dstport="110" srcip="89.59.133.233"
POP3-connections from internal to the web are no problem. Internal
connections over the proxy without dnat have also no problem.
when a connection is with dnat the proxy have a big problem.
the client software (thunderbird) give an "empty" error message
and no emails are transmitted.
thank you for tipps and bugfixes..
...edit...
this dnat-rule with pop3-proxing works fine at v6.
the packet-filter log shows nothing about this problem.
when switching the pop3-proxy to off the problem is away.
