Hi,
I just tried the below with the current version 1.0 RC15 and I still got the Problem: telnet gives me the following output: -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- +OK dovecot ready.u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r -ERR invalid command u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r _-ERR invalid command _ 1-ERR invalid command 1
-ERR invalid command -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<-----
The above output results from the following entry: user user_1[ENTER]
So now I know that this is no version issue. Can you tell me something on how I can find the solution for this problem? I don't think its a firewall issue, I disabled my Desktop Firewall. On the server I use shorewall, but of course, port 110 is open and it works disabling AntiVir on the client side. The error also occurs when I disable the Server Firewall as well. The error is reproducible on several PCs (I tried 3 PCs). Have you got any hint? Without solving the problem, I have to switch the pop3 server to another one, because this problem is really a crucial one.The only problem is: I loke dovecot. :)
Thanks in advance! Regards, Michael

Hi,
I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4 (CentOS-4.4), but why I'm asking this is whether it's worth to switch from rpm based upstream dovecot to a self compiled one or not and thus I think you wouldn't kill me presenting you this question. o:-)
I've got a problem with dovecot regarding a pop3 proxy issue. When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this:
pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42]
Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login.
So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue? Thanks in advance
Michael
