Do you have too many emails? More than 100 000 or so? Can’t find old emails anymore?

I installed a program called MailStore Home program on my Windows computer. With this program you can connect it to all your email accounts, and it will download everything, index it and compress it.

In my case I have around 100 000 emails spread on 3 email accounts.

When I have to find an old email I know I have, I used to spend a long time searching in Thunderbird, Outlook and on Gmail. It could take me an hour sometimes. But, now, it only takes a couple of seconds.

All my emails are stored in about 5GB, so I can carry everything around on a USB stick. Quite handy!

Also, MailStore Home can works as a offline email backup storage. Quite handy if you by mistake delete an email!

Downgrade to previous version: yum

Sometime yum update just breaks everything. We experienced this, and had to go backup to previous versions.

In RHEL6 and RHEL7 you can run this command:

which will give you a list of transactions ID’s. Now you just need to figure out how far you want to go back in the history, and do the roll back with:

where N is the number of transaction ID.

[code lang=”bash”][root@P1servername01 tmp]# yum history list all
