Courier IMAP - vpopmail troubles

I like the qmail/vpopmail solution as a email server a lot and use it in lots of places. Usually there is only one domain, but in one special case I had to create more than one. I also use courier-imap as imap/pop3 daemon because of its support for vpopmail.
So last week I went to create a new virtual domain on this site and at first all seemed to work fine, but after a while users on the new virtual domains reported login errors.
After some googling I searched the vpopmail mailing lists and found the following posts:

Since I usually install qmail on SuSE linux systems I wanted to modify the rpm of courier-imap (version 3.0.8) so that it would also build the needed authvchkpw . This turned out not to be easy and required a modification to the spec file that I am attaching here:

To use it simply extract the courier-imap.spec file in rpm/SPECS and patch it. Then move the courier imap sources in rpm/SOURCES and build normally.
These are the directions for building courier rpms:

Indexing Apache access logs with ELK (Elasticsearch+Logstash+Kibana)

Who said that grepping Apache logs has to be boring?

The truth is that, as Enteprise applications move to the browser too, Apache access logs are a gold mine, it does not matter what your role is: developer, support or sysadmin. If you are not mining them you are most likely missing out a ton of information and, probably, making the wrong decisions.
ELK (Elasticsearch, Logstash, Kibana) is a terrific, Open Source stack for visually analyzing Apache (or nginx) logs (but also any other timestamped data).

From 0 to ZFS replication in 5m with syncoid

The ZFS filesystem has many features that once you try them you can never go back. One of the lesser known is probably the support for replicating a zfs filesystem by sending the changes over the network with zfs send/receive.
Technically the filesystem changes don't even need to be sent over a network: you could as well dump them on a removable disk, then receive  from the same removable disk.

Mirth: recover space when mirthdb grows out of control

I was recently asked to recover a mirth instance whose embedded database had grown to fill all available space so this is just a note-to-self kind of post.
Btw: the recovery, depending on db size and disk speed, is going to take long.

The problem A 1.8 Mirth Connect instance was started, then forgotten (well neglected, actually). The user also forgot to setup pruning so the messages filled the embedded Derby database until it grew to fill all the available space on the disk. The SO is linux.

The solution First of all: free some disk space so that the database can be started in embedded mode from the cli. You can also copy the whole mirth install to another server if you cannot free space. Depending on db size you will need a corresponding amount of space: in my case a 5GB db required around 2GB to start, process logs and then store the temp files during shrinking.

Then open a shell as the user that mirth runs as (you're not running it as root, are you?) and cd into the mirth home. …
