I have two servers that were installed identically using The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 2] User from outside sends email with 4.5Mb attachment to server #1 I am able to retrieve it using Outlook Express. But if same is sent to server #2 the message downloads to 86% then it stalls & finally Outlook Express notifies there is a time-out error. Code: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Support @ MP (Office)', Server: 'mail.office.******.net.au', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F Anyone know where I might start looking? Have already looked everywhere I can think of & even removed/re-installed Postfix on the offending server to see if it might help, but alas no go.
