My mail server is configured with a ISP. Now I want to configure Postfix to act as a local mail server for my organisation. For that I have configured it, its sending and receiving mails successfully. Problem I am facing is that 1.. when I download mail using fetchmail, fetchmail shows that it has downloaded mails from server but that mail but where it downloads mail I don't know, mail does not come into users mail box. 2.. I have two type of accounts on my ISP server. POP accounts and forwarding(catchall) accounts. POP account users directly download mails from ISP server using Internet. But forwarding mail account users use my local mail server to send/receive(pop and smtp) mails and on local mail server mails gets downloaded using fetchmail. Problem is when forwarding mail account user send mails to POP account users whose account is not on the local mail server using my local mail server as SMTP server, it returns error 'this mail account does not exist' and if I create a account on local mail server for a POP user, than this SMTP delivers mail to local made account instead of forwarding it to ISP mail server POP account. This is the biggest problem I am facing and consulted with so many people but no one has idea about its solution. Kindly help, this is a very common configuration and must be in use in most of the organisation. I am new to Mail server administration and don't know how to do it. <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> Thanks & regards Ashwani Jain </TD> </TR> </TABLE> </BODY> </HTML>
