I am using Red Hat Enterprise Linux AS release 4 (Nahant Update 5)and i am using send mail also..The issue is:
i am able to send emails from all OS users but unable to send mail from root user.(I am receiving mails if i send mails from all users except root user)what could be the issue?
am using qmail and have webmin, all is running smoothly, but i have users spamming other staff accounts.The question: How do I block a user from sending out mails but still able to receive mails. Just denying access to sending mails?if anyone can guide me to do it via terminal as well as webmin.Why webmin you ask, because I have tried it once it works but sadly it block both incoming and outgoing mails.

View 2 Replies View RelatedI have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.
Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.

SSH from PuTTY works fine for all users. The error I get actually says that the username or password is incorrect - checked using SSH and it is fine.

View 3 Replies View RelatedI've started to get emails that would typically come from [URL] as [URL]. These emails come from services that send out emails (backup programs) directly, or from cronjobs. I've logged in as the non-root account and either sudo su - or su - to root and the restart the service at one point or another. If I login directly as root and bounce the service or cron the emails come across as from root. I don't see anything in my environment variables after I su to indicate what would cause this. I'm not sure where else to look? A pam setting? This seems to have happened between Fedora 10 and 14 (did a bunch of overdue upgrades recently) I've only got Fedora so I don't have anything to compare to. In Fedora 10 I did not have this problem.

Basically I have a USB flash drive currently formatted under vfat. I can log in as root and the system automatically picks it up and automounts the drive successfully. What needs to happen is that a non-root user needs to be able write to this device while root has mounted this device. Due to other program constraints, I can not mount the device using another user so I have to do it with root.
