How to fix mysteriously disappeared Thunderbird e-mail message pane, Hide / Show Mozilla Thunderbird e-mail message window

Saturday, May 25th, 2013

Recently I did something so my standard Thunderbird e-mail message pane disappeared. I was not sure what happened so my logical guess was I had to do something from View menu, i.e. change something in:

View -> Layout or

View -> Toolbars

Anyways after taking close look in View, I realized can't fix it from there. So tried changing settings in:

Edit -> Preferences -> Advanced (tab)-> Reading & Display

I tried changing setting for Open messages in with no luck. Finally after some more googling I got the fix under Mozilla Community Q&A site here. The fix is as simple as pressing F8Pressing F8 makes e-mail message pane appear or disappear, like shown in below screenshots …. Thunderbird with missing e-mail message pane

That's all problem solved 🙂

How to change users quota to NO QUOTA on Qmail with Vpopmail Mail server install / Qmail mail over quota issue

Monday, February 20th, 2012

 

Qmail Vpopmail quota exceeded Dolphin Logo

Already on a couple of mail boxes located on one of the qmail powered mail servers I adminiter, there is an over QUOTA reached problem encountered.

Filling up the mailbox quota is not nice as mails starts get bounced back to the sender with a message QUOTA FULL or EXCEEDED MESSAGE, if this is a crucial mail waiting for some important data etc. the data is never received.
Below is a copy of the mail quota waarning notification message:

Your mailbox on the server is now more than 90% full. So that you can continue
to receive mail you need to remove some messages from your mailbox.

As you can read from the copy of the mail message above, the message content sent to the mail owner whose quota is getting full is red from /var/vpopmail/domains/.quotawarn.msg

The mail reaching quota problem is very likely to appear in cases like low mailbox quota set, but sometimes also occurs due to bugs in vpopmail quota handling.

Various interesting configuration settings for mail quotas etc. are in /home/vpopmail/etc/vlimits.default file, (assuming vpopmail is installed in /home).

In my specific case, the default vpopmail mailbox quota size was set to only 40 Megabytes.
40MB is too low if compared to todays mailbox size standards which in Gmail and Yahoo  mail services are already a couple of gigabytes.
Hence to get around the quota troubles, I  removed the quota for the mail.
To remove the quota size in vpopmail set for address (email_user@my-mail-domain.net) used cmd:

qmail-server:~# vmoduser -q NOQUOTA email_user@my-mail-domain.net

To save myself from future quota issues, I decided to apply a permanent fix to all those over quota size VPOPMAIL mailbox problems by removing completely quota restriction for all mailboxes in my vpopmail existent mail domain.

To do so, I wrote a quick simple bash loop one-liner script:

qmail-server:~# cd /home/vpopmail/domains
qmail-server:~/vpopmail/domains# cd my-mail-domain.net
qmail-server:~/vpopmail/domains/my-mail-domain.net# for i in *; do \
vmoduser -q NOQUOTA $(echo $i|grep -v vpasswd)@my-mail-domain.net; \
done

This works only on vpopmail installations which are configured to store the mail messages directly on the filesystem. Therefore this approach will not work for people who during vpopmail install had configured it to store mailboxes in MySQL or in other kind of SQL db engine.

Anyways for Vpopmail installed to use SQL backend, the script can be changed to read directly a list with all the mailboxes obtained from databasae (SQL query) and then, loop over each of the mail addresses apply the vmoduser -q NOQUOTA mail@samplemaildomain.net.

I've written also a few lines shell script (remove_vpopmail_emails_domain_quota.sh), it accepts one argument which is a vpopmail domain to which the admin would like to reset all applied mailbox quotas. The script is useful, if you have to often remove all quotas for vpopmail domainsor have to do quota wipe out simultaneously for multiple email domain names  located on different servers.
