I tested the proxy quite a lot and in 5.003 it definitely works for me here, I proxy internal network -> Any and have all the features turned on, tried large attachments and can't find an issue at all. The only minor thing I found is that the reporting doesn't show the spam score and the logfile only shows the IP addresses and not the email addresses as it was in V4.
ok OE does not check multiple accounts simultaneously but serially. Use mozilla mail and setup all both pop3 accounts in it. Set them all to be checked and downloaded on startup. Shutdown mozilla wait a second then bring it back up so all three get hit at once. Use OE send send one of your 3-5 megs attachments and let's see what ahppens..[:)] YMMV
I experience the same problem! After Upgarding to 5.0.3 my POP3 Proxy does not connect correctly anymore. When connecting with the mozilla mail client i get the error message: "The RETR command did not succeed. Mail Server pop.gmx.net reported: scanner error : Scanner Error"
