This is a multi-part message in MIME format. --===============8243925338721622581== Content-Type: multipart/alternative; boundary="------------ACE5A02E2D9758C1729183B8" Content-Language: en-US This is a multi-part message in MIME format. --------------ACE5A02E2D9758C1729183B8 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Bobby, The reason for finally upgrading to a newer version was the TLS support in the newer version. With 2.2 I was able to run things through stunnel, but many clients, Outlook being one, started defaulting to STARTTLS instead of using the SSL port. This caused many of my users trouble setting up accounts on their computers. So, I decided to upgrade so STARTTLS would work. Another reason for upgrading is that I has having trouble compiling the older 2.2 version on a newer OS. The older code needed older libraries and it was getting hard to get them all to work, while upgrading to newer code was easier. When doing the upgrade, the most amount of time was spent doing the header conversion. I recommend adding the entry "header_cache_readonly = yes" to dbmail.conf after you have the needed header name values. On my hardware with the number of messages I had it took over 4 months to do the conversion. (2.6 million messages.) If I had put that line in, it would have taken only a few weeks. During the conversion I had two databases setup, dbmail22 and dbmail3, then added triggers to insert and delete rows when things changed in dbmail22 so the dbmail3 database had all the same messages. This way all my users could still use IMAP and when the conversion was done and tested, I just moved the IP from my old mail server to the new, running the new version, and there was only about half hour of downtime. Other than this issue with CONDSTORE, which happened several weeks after I started using 3.2, I have had little trouble with the basic use of DBMail 3.2. I wish that dbmail-timsieved also supported STARTTLS, but I see that as optional and haven't opened that issue yet. I've also noticed that it takes 3 to 5 seconds to insert a message, which is tolerable for mail delivery, but when an IMAP client is moving messages to the server, it takes a LONG time, but this doesn't happen often. I hope that some of these things help when you decide to upgrade to 3.2. I still need help getting CONDSTORE working again!!!
