hey friends, I want to configure postfix.I have 2 catch all mailboxes with 2 different ISPs.I want to configure postfix in such a way that it should be able to handle mails for both the domains like nextegen.com and sunupdelhi.net.Now the problem is that both the accounts require authentication with the ISP's mail server. I have configure postfix with smtp_sasl_auth_enable and other configurations are also done for one account.But I am not too sure how to handle the second account. Suppose there is a user john having mail account on the local mail server.Whenever he sends the mails to the outside world the local mailserver should contact or authenticate to the ISP's mail server to send the mail doing so prevents the mail accounts going into the spam list. Now the problem is that how to handle the 2 accounts as both requires authentication. I have given relay entry for one account like relay: xxx.xxxx.xxxx with one file created on the Linux where the user name and password are stored for this mail account.Whenever any mail from the Local Mail server goes to the outside world it first contacts the ISP's mail server and then forward it to the real user account/mailbox.I am using virtual domain for sunupdelhi.net as my local domain is different from this domain. I have few more queries I don't know the use of sasldb/sasldb2.I have installed cyrus-sasl on my Linux pc and using sasldb2 for the users.Even though some users are not part of that database but still they are able to send mails to the outside world and within the Lan.Can anybody tell me whether smtp_sasl_auth_enable should work without entring the users in the sasldb2 database. The entry for /usr/lib/sasl2/smtpd.conf is pw_check:auxprop and mech_list:plain login. Second if I want to restrict a machine(any server) from which any user cannot send any mail whether within the Lan or outside Lan and also whether it is possible to restrict any particular user from sending the mail from any machine. I have configure squirrelmail for Imap.The code for squirremail in httpd.conf is like this Directory "/usr/share/squirrelmail"> Options Indexes MultiViews AllowOverride None Order allow,deny Allow from all </Directory> I can access the squirrelmail from Lan and from outside also.But I want is that if somebody type http://192.168.0.90/webmail for accessing squirrelmail ,the apache should itself redirect the http: to https means the url should become https://192.168.0.90/webmail Is it possible for squirrelmail. I am using dovecot as pop server. Today I am at home so i don't have the postfix configuration file(main.conf),but if somebody needs that I can mail it tomorrow. Thanks in Advance Thanks & Regards Ankush
