I have recently noticed a growing problem and am curious if anyone else is seeing the same. There are certain email servers that I am not able to reach. I get a "read timeout error" I used the standard 'telnet mailhost 25` to troubleshoot and found that I am able to reach certain site just fine. That being I get the RFC required banner. While others I get nothing. It started out as some .gov sites (e.g. fernald.gov). But now we are unable to reach AOL.com as well. I have even gone as far as looking at the packets with a sniffer. I DO find differences. The response coming back is different. The REAL kicker is that the results vary by OS and connect type, RH8 - LAN connection - doesn't work here but does in another geographic location Windows XP - LAN - 2 different locations - doesn't work Windows XP - Dialup - works MAC OSX - LAN - Location 2 - works The server used for the test case is running Sendmail 8.1.??. I am running postfix 2.0.19 on Redhat 8. Anybody seeing this or have any ideas. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
