Re: [qmailtoaster] CNAME lookup failed temporarily -- workarounds?

2018-02-26 Thread Peter Peltonen
Hi,

I was hit by this error on a server running qmail-toaster-1.03-1.3.22

This patch is not included by default in the toaster qmail package?

Strange thing is that the error came from a host that has proper MX
records (MX pointing to a A record, not CNAME), so I am wondering what
exactly is triggering this error...?

Regards,
Peter

2018-02-19 Thread Angus McIntyre

Eric, very many thanks for this.

I've done the upgrade using the RPMs that you provided and, touch wood, 
everything seems to be going smoothly.


The only problem that I encountered (so far) was with authenticating on 
submission. This turned out to be a softlimit issue: softlimit had 
reverted to its original, lower value in a couple of the supervise 
scripts, and this was stopping a shared library loading. Once I put the 
softlimit back to what it should be, everything returned to normal.


Once again, many thanks for your help with this, and with qmailtoaster 
in general.


Angus

Jeff, 
I see your msg below. I have moved boxes around. I found easy to create the new 
users on the new box and rsync the data over from the old box to the new.. 
Cleaner and much faster way. Anyhow, that’s my two cents here!

Thanks for that Jeff, yes YMMV and every situation is different,
  my old server was a mysql version and didn't have those
  challenges. For sure set up the new box and test things prior to
  changing DNS. Until you change DNS, everything is still on the old
  box giving you time to test and determine if you're ready to go.

  Angus - I would be very
cautious about switching if you've been using the non-mysql
(cdb) version of the qmail toaster and you have many domains on
the mailserver. You'll have to run a bunch of scripts to convert
vpasswd and the dot-qmail forwards to the mysql format. And each
domain has to be handled individually. I did this conversion
with a mailserver with 150 domains and it took several days.

The good news is that Eric Broch recently put together a CDB
version of the QMT 7 and I just finished converting a mailserver
with 20 domains. It went much faster. I was able to tar-zip and
dump in the entire /home/vpopmail/domains directory. Of course I
had to update things in the /var/qmail/control and /users
directories and setup some symlinks to handle changed locations.
I'm still standing by and listening for user comments but it
seems to be working very well.

Next, I plan to tackle two old qmail servers with over a 1000
domains each.

For what it's worth, I was in the same boat last year and

  the guys have done a great job of supplying us with RPMs and

Moving over all the old mail was likewise very easy and just
  worked. I rsync'd from the old box to the new. The tricky part
  is cutting the users over. You need to set your DNS ttl to
  something really low (I first set mine to 4 hours, then to 1
  minute the day of the cutover). That makes your mx and A
  records move very quickly. At cut time, change your dns, do a
  final rsync of all the old mail, make sure you're ownership
  and permissions are all right and you're done. 



The transition was much smoother and easier than I had
  thought and everything worked like a charm. 



So while it's not what you're looking for in terms of a short

  It's really not that bad and will clean up your entire
