Sorry im really new at the whole mail list forum thing, where abouts would the example be i've had a quick search and can not find it :( At present I run the following command: fetchmail -d 300 -mda -v -f '/home/mailbox/.fetchmailrc' pop.freeserve.co.uk (so do I not need the -mda switch?) And my fetchmailrc file looks like this: poll pop.freeserve.co.uk proto pop3 aka "myhostname.freeserve.co.uk" user "ISP username" pass "ISP password" nokeep fetchall The problem is if for instance BOB@xxxxxxxxx sends PHIL@xxxxxxxxxxxxxxxxxxxxxx an email which is incorrectly spelt e.g PHILLL@xxxxxxxxxxxxxxxxxxxxxx , BOB@xxxxxxxxx does not get a email back to inform him that the email was incorrectly delivered and instead, the "UNDELVERED MESSAGE" goes back to the MAILBOX user on the local machine. Sorry if im crap at explaining myself (lol it is 2:56 am here) -- Regards, Phil -- This message was scanned for spam and viruses by BitDefender For more information please visit http://linux.bitdefender.com/
