Postfix smtp relay simple postfix relay how to, postfix relay-how-to. postfix+squirrelmail how to configure.. Server is providing the following services: == Primery DNS Mailing System : Webmail / POP/IMAP client Web Server : for rvpn.co.in Packages Used: == OS : Redhat AS - version 2.1 (RHAS21) apache-1.3.23-10 --- Webserver daemon (service httpd start/stop/status) imap-2001a-15 : POP3 access to Outlook and Edora client Postfix-2.0.13-3.1.rhas21 --- MTA squirrelmail-1.2.7-4 --Webmail for Postfix Imapd squirrelmail-plugins compatibility: 1) change_password---3.1-1.2.80-- change pass of user through webmail 2) compatibility 1.3 -- required for change password option Remark: === 1)when installing this squirrelmail error like httpd required will be popup just ignore it puting rpm -Uvh squirr*.rpm --nodeps. it works. 2) After this entry is required in /etc/httpd/conf/http.conf for alies for /webmail option in the web browser 3) if POP client like outlook express dosn't work. some relay related problem has to be sorted out in the main.cf files. To relay local LAN user in POSTFIX I did the following things: + inet_interfaces = all mynetworks_style = subnet mynetworks = 210.212.60.0/24 192.168.17.0/24 192.168.18.0/24 smtpd_recipient_restrictions = permit_mynetworks check_client_access hash:/etc/postfix/client_access check_sender_access hash:/etc/postfix/sender_access reject_unauth_destination Note : create the file in /etc/postfix for sender_access and check_client_access.

Here is live and running Postfix main.cf file configuration: # readme_directory: The location of the Postfix README files. # readme_directory = /etc/postfix/README_FILES alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/postfix/aliases mydestination = pushkar.co.in myorigin = pushkar.co.in masquerade_domains = pushkar.co.in #fallback_transport = smtp:ns.pushkar.co.in inet_interfaces = all mynetworks_style = subnet mynetworks = 2sdsfsdfs60.0/24 192.168.17.0/24 192.168.18.0/24 smtpd_recipient_restrictions = permit_mynetworks check_client_access hash:/etc/postfix/client_access check_sender_access hash:/etc/postfix/sender_access reject_unauth_destination hummm Pushkar Bhatkoti ARTEK ENTERPRISES PVT LTD Nehru Place New Delhi India 45 Deepak Bldg Nehru Place India Mobile : 9810774912 mail : [EMAIL PROTECTED] yahoo : [EMAIL PROTECTED] Its just cook.

[SLUG] Kernel panic: DMA pool Exhausted in RHAS 2.1
Dear All, Just faced this problem with the RHAS-2.1. I seen this message kernel panic: dma pool exhausted and server gets hangup. I tried to google and all but didn't find proper solution. Finally I gone to kernel level debugging. I installed teh debugging kernel from kernel.org. And observed the log after boot and b4 boot and when rhas-21 gets hanged. Can't believed it was the problem with my hardware based raid. I was using U-320, 320 u adaptec make dual channel SCSI PCI card. actually the driver supplied with this server (server is Wipro make , only in India) but server is intel based motherboard was for RH7.3. I finally downloaed the rpm named aic7xxx-6.2 and patched it to kernel. It worked fine. and since than it is working fine. otherwise system gets hangup everytime when it starts to insert or eject the modules in the kernel. So finally, if u face this sort of the problem please try to make the dd disk for 320 card using dd if=/dev/fd0 of (image name). image can be download from apaptec.com site. and than start fresh installation. If u will do like me. I installed the system rhas-2.1 with rh7.3 driver and than I upgraded using the rpm provided by adaptec. Additionally the symptrom for this hardware realated problem is when u tried to installed any rpm using rpm -ivh or rpm -uvh u will get the same error log i.e. kernel panic: dma pool exhausted and u need to power down adn up it through switch... greattt. just don't be fool its very simple to get resolve it... Cheers!! enjoy any prblem pls feel free to contact me..
