Hi guys, Big fun I started to convert from Mandriva to Ubuntu and have set-up both these using the "Perfect set-up" however the native pop3d on Mandriva authenticate via pam and retrieve mail from folder /var/spool/mail/username. On Ubuntu the courier suite is used and the pop3d can not work unless against Maildir setup. The Ubuntu setup was The Perfect Setup - Ubuntu 6.10 Server (Edgy Eft) Page 5 and the Move instruction used many times between servers was Moving ISPConfig I also added the FuzzyOCR, Pyzor, Ryzor, DCC, Postgrey as per this forum instructions. All tests passed! The problem is that I can find how-to’s on converting to Maildir on Mandriva but it discard the "old" mail (couple Gig's) and start fresh. I can not use fetchmail either as the passwords are MD5 or otherwise encrypted, changed by user etc. ( I have not investigated the possibility to run fetchmail with those encrypted passwords). I presume I could change all passwords to one I know and afterwards replace the passwd/shadow file from backup -- hmmm would need to think about that one. Any case I'm stuck, If anyone have answers to quick solving this without causing long downtime - please let me know. Normally the above move take only 5 minutes to backup and restore the data once the replacement server are set-up, that is not a great deal of downtime. I think the best method still would be to 1st convert to Maildir BUT that has to migrate old mail content also.
