    hello,

    I have configured postfix last month ...for my local lan ..now i want to configure it for my website hosted on dynamic Ip and using dyndns.how to do this ?..can i configure it for local as well as internet simultaneously ?..
    i made some changes as mydomain=mysite.org and myhostname=mysite.org ..in main.cf but no go.

    i am using google mail as realaying server ..but i can see all the mail going to google with my local domain name ..as
    [email protected] (configured for lacal lan).
    so reported as:

    Oct 6 16:17:55 serv postfix/smtp[16195]: A3C088C11C: to=<[email protected]>, relay=smtp2.google.com[64.233.167.25], delay=6, status=bounced (host smtp2.google.com[64.233.167.25] said: 553 5.5.3 <[email protected]>... Invalid (in reply to RCPT TO command))

    Create MX records for your email domains that point to your DynDNS address.

    What's in your /etc/postfix/main.cf?

    Even it does not helpd for your problem, I would never run a mailserver on a dynamic IP.
    A server shall have a static IP especially in times of SPAM, so many ppl drop mails from dialup hosts (having dynamic IPs), so do I.

    ok.. let me explain about the problem more briefly.

    i am running a web server apache ..with dyndns as vareesh.homelinux.org
    with postfix, squirrel mail ..
    1. My host name is serv.lin.ald
    when someone type vareesh.homelinux.org can see it. and my web forms and comments are forwarded to smtp server.i use squirrel mail to see them.
    i can send/receive mail to all the local accoounts .
    now can i use something like say [email protected]
    instead of [email protected] because i can not use serv.lin.ald for internet mail.
    for this i made changes in main.cf and squirrel mail (./configure) but imap error at login.php....when this whole setup was done it wasnt for internet ..but now because i am running web server my mail need to be forwarded to respective mail server.

    @Falko ..you are right about the MX record ..but i am not able understand it how and where to include these records (which zone file).I have manged to configure a dns (bind) for local lan ..

    so do i need to change
    1. my hostname from serv.lin.ald to vareesh.homelinux.org ?
    2. change for mydomain as vareesh.homelinux.org , myhostname as vareesh.homelinux.org in main.cf.?
    3. Changes in sqquirrelmail ?
    4. MX entry in dns zone. ?

    pls advice.

    thanks

    I'd use vareesh.homelinux.org for myorigin, mydomain, and myhostname.

    Make sure that you set the correct sender address in your email client so that Google accepts the mail.

    Thanks falko..but no its not working ..with vareesh.homelinuix.org as my origin,mydomain and myhostname..do i have to include my destinations option in main.cf ?

    one more thing ..whenever i change the imap and smtp setting (through ./configure) in squirrel as domain vareesh.homelinux.org i get permission denied error during login process (login.php) ....
    see the error messages ....mail going with @serv.lin.ald.. thats the problem ..
    how to make them as @vareesh.homelinux.org..and say if it goes with @vareesh.homelinux.org will it be acceptable d by gmail ?

    Outlook, Thunderbird, Squirrelmail, etc. are all email clients.

    When you're logged in in Squirrelmail, you can change the sender address in the preferences.
