pop3 session would freeze

[Ufuk M. Fakioglu]

Hi,   I am using qmail 1.03 + vpopmail 4.9.8 on Solaris 2.7 and MS Outlook Express as pop3 client.   While retrieving messages, without any obvious reason, the pop3 session would first freeze and then Outlook would display an error message saying that it cannot communicate with the pop3 server for 60 seconds. The message counter on the client side would start to increase and then suddenly stop at some arbitrary mesage like "receiving messages 14 of 25" and freeze like that.   Any suggestions will be dearly appreciated.   Regards,   Ufuk
