Qpopper has been performing very well for us but lately (within the last month) we've begun seeing quite a few (50 or more per day) of these type of messages in the /var/log/maillog file (times, usernames, and IP's have been changed.)
Dec 14 HH:MM:50 mailserver14414 popper[20830]: (v4.0.8) Servicing request from "www.xxx.yyy.zzz" at www.xxx.yyy.zzz Dec 14 HH:MM:50 mailserver14414 popper[20830]: (null) at www.xxx.yyy.zzz (www.xxx.yyy.zzz): -ERR POP EOF or I/O Error Dec 14 HH:MM:50 mailserver14414 popper[20831]: (v4.0.8) Servicing request from "www.xxx.yyy.zzz" at www.xxx.yyy.zzz Dec 14 HH:MM:50 mailserver14414 popper[20831]: (null) at www.xxx.yyy.zzz (www.xxx.yyy.zzz): -ERR POP EOF or I/O Error Dec 14 HH:MM:37 mailserver14414 popper[5619]: someuser15357 at www.xxx.yyy.zzz (www.xxx.yyy.zzz): -ERR POP EOF or I/O Error Dec 15 HH:MM:10 mailserver14414 popper[29457]: someuser1383 at www.xxx.yyy.zzz (www.xxx.yyy.zzz): -ERR POP EOF or I/O Error Dec 15 HH:MM:10 mailserver14414 popper[29457]: Stats: someuser1383 0 0 4 471851 www.xxx.yyy.zzz www.xxx.yyy.zzz These occur anytime of day or night, and this behavior lasts anywhere from a few minutes to a few hours. We had an eposode that ran for about 2-1/2 hours yesterday. Strangely, some of these occur with a user account (e.g. someuser15357 and/or someuser1383) are in the -ERR POP EOF or I/O Error line, but the vast majority of these -ERR POP EOF or I/O Error lines have "(null)" as the username. Would appreciate any ideas. No other issues with the version of Qpopper we're running, even though it's a bit older (v4.0.8) so I'm not inclined to think it's the age of the build. OS is RHEL4 WS Linux. Thanks! ========Keith
