Greetings,
I have long read and followed this list. I have also spent a considerable time with our good friend Google.
I am a long time Sendmail user, about 15 yrs now. I have recently been looking into the newer services and the Postfix setup seems to be a very nice one. I am migrating a mail server from 3.x to 4.x and was intending on trying out Postfix on the 4.x server. I have found /alot/ of HowTo's covering various Postfix implementations. I have tried a few of these to various stages, some completely, some partially. I have not however found one that would take a CentOS 4.x system from Sendmail to Postfix completely. I can get Postfix to work. I can get MySQL to work with in some cases Cyrus and Courier for the IMAP services. I can get some Virtual Domain working but not completely. I can't however get it to actually work all together. I have a bit of ignorance with Cyrus/Courier IMAP as I have previously just had a simple Squirrelmail to Sendmail with stock IMAP services and all my users previously were real UNIX accounts, which I am trying to not require now.
Does anyone have a real HowTO that goes from a stock 4.x load to Postfix etc.? I have follow Hughes HOWTO but it also skips the Courier/Cyrus part. I have gotten it all working except it doesn't make any MailDirs so then Squirrelmail freaks with Invalid Mailbox errors. It's quite frustrating to me because most of the HowTO's skip steps, like getting users into the SQL (which I have figured out a few times). It would be nice to have a real HOWTO that does /all/ the steps from stock to this configuration.
If I have missed previously posted good HowTo's please point me to them and I apologize for the oversight. I have done many google/mailing list searches and they all seem to be 'almost' a how to.
Thanks for the Help.
Brent
