We use the imailuser extract and mail the file to the postfix server. then = setup a .sh script that processes the mailed file into a map file.
you can decide on frequency of both by scheduling them as you see fit. you also have to have a sh file and an entry in the /etc/aliases file that = references what to do when the mail arrives on the imgate box. >-----Original Message----- >From: Ed Butler (49pence) [mailto:[EMAIL PROTECTED] >Sent: Sunday, March 28, 2004 5:55 PM >To: [EMAIL PROTECTED] >Subject: [IMGate] Imail/IMGate newbie question > > >Decided to summarise my quite verbose email after writing it: >1) What kind of load can Imail cope with, using two postfix helpers >2) What's the accepted/preferred way of exporting domains from Imail to >IMGate on a regularly changing config >3) Preferred AV solution > >We've just recently switched from Merak (www.icewarp.com - tons of =3D >features, >poor stability) to Imail.
