VPOP3 v7.1 Released
Posted by Paul Smith on 16 February 2017 11:25 AM

We have released VPOP3 v7.1 which you can download from http://www.pscs.co.uk/downloads/vpop3.php.

This is a free upgrade for all users who have active software maintenance or priority support on 15th February 2017. Other users can purchase the upgrade and 1 year of software maintenance on our website.

The full change log can be viewed in our issue tracker.

Main Changes in v7.1

  • New: Add report to show messages sent through a Mail Sender between two dates.
  • New: Add chat facility to VPOP3 settings for people with support contracts.

  • Fix: Message Archive search on message content wasn’t working properly.
  • Fix: Diagnostics -> Message Search wasn’t working properly with subject searches.

64 bit version

This release has the first public 64 bit version of VPOP3. Here, we have been using the 64 bit version for about 6 months, so we are confident it is OK.

The main advantage of the 64 bit version is that VPOP3 has access to all the memory on the computer, rather than just the first 3GB. In most cases this won’t make any noticeable difference, but if you regularly send or receive very large messages (eg over 40MB) then it should improve performance and reliability.

Installing the 64 bit version is straightforward, and you can switch back and forth between the 32 bit and 64 bit versions with ease by simply reinstalling the appropriate version over the top. (The configuration & data storage is identical, it’s just the EXE and DLLs files which have to change).

Both the 32 and 64 bit versions of VPOP3 use the 32 bit version of PostgreSQL because there is no real advantage to changing that, and it would require a time-consuming backup/restore of the database to change to the 64 bit version. (Note that both versions VPOP3 will also work with the 64 bit version of PostgreSQL if you wish to migrate that manually).

Note that because we don’t have access to the relevant components, there are a couple of limitations with the 64 bit version:

  • The 64 bit version cannot access some of the data from version 4 or earlier, so it will not be able to migrate the data across properly. For this reason, if you are still using version 4 or earlier and want to upgrade to the latest version, we recommend that you upgrade to the latest 32 bit version first and run that for a week or so, so that it can migrate the data. Then, reinstall the 64 bit version.
  • The 64 bit version does not currently contain the Webmail Spell Checking facility.

The VPOP3 Antivirus and Spamfilter work fine in the 64 bit version, but you need to install the Antivirus component from the 64 bit installer because the 32 bit download version will not work with the 64 bit version of VPOP3.

Chat Icon

In VPOP3 7.1 we are experimenting with a Chat facility for users with a Priority Support contract. If you have a support contract and we are available, then you will notice a green chat ‘bubble’ at the bottom right of the VPOP3 settings screens. Clicking on that should open a chat conversation with us which you can use for technical, sales or general customer support (if suitable staff are available).

(This facility may be removed in the future, depending on how things go).

VPOP3 v7.0 Released
Posted by Paul Smith on 19 January 2017 03:16 PM

We have released VPOP3 v7.0 which you can download from http://www.pscs.co.uk/downloads/vpop3.php.

This is a free upgrade for all users who have active software maintenance or priority support on 8th November 2016. Other users can purchase the upgrade and 1 year of software maintenance on our website. Version 7.0 has been available as an ‘early access’ download on our website for a couple of months, but we have moved it to the main download now.

The full change log can be viewed in our issue tracker.

Main Changes in v7.0

  • New: Switch to PostgreSQL v9.5
  • New: Add option for Full-Text-Search indexing of messages if desired
  • Fix: Admin pages don’t work in IE if Compatibility Mode is on
  • Fix: Spamfilter updates not working sometimes
  • Fix: Problem with IMAP4 IDLE command if ‘allow any line endings’ is enabled
  • Fix: In IE, Edit User window has unnecessary scrollbar at right
  • Fix: Improve IMAP4 search performance in many cases

The biggest change is that VPOP3 now needs PostgreSQL v9.5 or later. VPOP3 versions 5 and 6 required PostgreSQL v9.1 or later. PostgreSQL went out of support in 2016 and later versions have more features that we can use. The upgrade from PostgreSQL 9.1 to 9.5 is done by the VPOP3 installation program. It will display the upgrade process as it happens so that the installing user can check it has upgraded OK before continuing. This process should be relatively quick (a few minutes in most cases) and won’t use much extra disk space so shouldn’t cause any problems.

VPOP3 v7 upcoming & beta-testers wanted
Posted by Paul Smith on 22 June 2016 08:53 AM

The next version of VPOP3 that we are planning will be version 7. We are changing from the 6.x sequence because we are planning two relatively major changes:

  1. Change from PostgreSQL 9.1 to 9.5
  2. Release 64 bit version of VPOP3

People with active support/maintenance agreements at the time of its release will be able to upgrade to version 7 as part of that agreement.

We are anticipating release around late September 2016.

Change from PostgreSQL 9.1 to 9.5

PostgreSQL 9.1 is nearing end-of-life in September 2016. While we haven’t encountered any major problems with it, there are many improvements in later versions of PostgreSQL which will help performance and also make some things that VPOP3 does easier.

VPOP3 already runs on any version of PostgreSQL from 9.1 or later, but it is quite a major process to upgrade the major version of PostgreSQL. This is why we have not previously kept up with the latest versions of PostgreSQL in our standard installation process.

When going from VPOP3 v3/4 (which used PostgreSQL 8.3) to v5/6 (which uses 9.1) we had to backup & restore the full database which could take several hours for some users. This was required because the build method of the pre-built PostgreSQL binaries had changed between 8.3 and 9.1.

However, the build method of 9.5 is compatible with that of 9.1, so we can use a ‘shortcut’ method using a program called pg_upgrade. When we have tested it here, it takes just a few minutes to upgrade a 30GB v9.1 database to v9.5. It is slightly complex so we will be trying to automate it for you.

One of the ‘disadvantages’ of using pg_upgrade is that we cannot convert the database to work with a 64 bit version of PostgreSQL, so we will have to stick with a 32 bit version of PostgreSQL even for the 64 bit version of VPOP3. We don’t anticipate this being a problem. If you want to use a 64 bit version of PostgreSQL, that will work fine with VPOP3, but you will still have to do the full dump/restore process to migrate the database in that case. This won’t be part of the standard installation procvess.

Release 64 bit version of VPOP3

For a while we’ve been wanting to release a 64 bit version of VPOP3. Tests we’ve done show our 64 bit builds working fine. There are a few limitations with the 64 bit version we are working with so far:

  • it requires Windows 2008/Vista or later (not that big a problem since 64 bit versions of Windows XP were rare)
  • it doesn’t support the standalone fax plugin (but will support the PAYG fax service)
  • it doesn’t support WebMail spellchecking (we may look at trying to re-add this if there is enough interest)
  • it doesn’t support the VPOP3AV antivirus plugin. We will be working on this (we don’t anticipate any problems implementing this, it’s just a lack of time so far)

(The above are mostly not because of any problems with the 64 bit VPOP3, but because we use third party components for which we do not have 64 bit versions, so adding them will incur extra licensing costs for us).

The 64 bit version of VPOP3 should alleviate some problems we have encountered in a few cases.

The main one is that problems due to virtual address space fragmentation should be practically eliminated. This problem has caused issues when people have tried to have VPOP3 process very large emails (>100MB).

VPOP3 will also have access to more than 3GB of memory. This shouldn’t solve any existing problems by itself, but it does mean we can consider adding more in-memory caching for some data to improve performance.

Beta testers wanted

Because of these relatively major changes we would like some people to try it out before release. Please contact us via https://support.pscs.co.uk if you are interested in this. We will be testing it on our internal mail servers and test PCs first, but it is good to try it in different environments as well.
