Hey guys, sendmail-8.12.11-4.21AS.8 on rhel-2.1, having a strange problem: userA@xxxxxxxxxxxxx sends email to userX@xxxxxxxxxxxxxxxxxx just fine. userB@xxxxxxxxxxxxx, though, cannot send email to userX, his messages get bounced with a delayed Status: 4.4.1. messages from userB to other places go through fine. if userB uses our CRM to send email to userX, it goes through fine as well. no clue where to begin working on this. Any clues are appreciated. Thanks, G -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
