I have an external Mail server mail.mydomain.com located at an hosting company outside
i have an internal mail server configured with sendmail for internal mail server
domain = interaldomain.com
i have configured SMART HOST in my internal mail server to relay mails to my external mail server . i have configured Outlook express to my users as pop3 and smpt as mail.internaldomain.com and mail.internaldomain.com respectively .
i have configured fetchmail for the user in my internal mail server , such that a copy exists in my external mail server .
poll mail.mydomain.com with proto pop3
there with pass "password" is user here
and configure fetchmail for that user in his crontab as like this
*/5 * * * * fetchmail -k -s .
I have configured user outlook express , but the problem is when ever i click on send/receive i get the mails which i have already got, again when ever i click send/receive i get same mails again and again.
i want a copy to exist in my external mails server and but i don't want them to download again and again.
if i remove -k in the above fetchmail command, user is able to downloaded mails and mails are coming only once.
But i need a copy to remain in external mail server
Please guide me
