| For a long time I used the Mail Server Pro, and updated to the newest version. NET but I have had serious problems in the performance of my server.
I have a server Pentium 4 3.2Ghz 2Gb Ram with Windows 2003 Srv and there are 200 users mailboxes .
In the old version Mail Server Pro was half the performans and never had problems.
The server using up 90% of CPU in the process AGMSService.exe, but it takes SQL total 100% and freezes once or twice a day, and sending and receiving mail is very slow, " What can I do to fix this?

| I've been using the .net version for a while now and it's been running like a champ until the latest version - v1.0.7.3 - and I'm now seeing AGMSService.exe consuming all the CPU resources all of the time. With or without anyone connected. It's become totally unusable. |

| The first thing that comes to mind when this happens is that there is a third party application accessing the files. This could be a real time anti-virus program, a back up utility or something else. Have you made any other changes other than upgrading to the latest version of .NET mail server? I just did the upgrade just a few moments ago and I will be monitoring my system for these events. |

| I made no other changes at all. I uninstalled the previous version, installed the latest version and watched performance die completely on the computer.

| BetyG,
What are your system Specs? How much RAM, OS & Service Pack, How large is the Hard Drive and how much is available? |

| Thanks for the response My server is Pentium 4 3.2 Ghz, 2 GB RAM with Windows Server 2003 Std Edition and SP2. The hard drive is 250 GB SATA with 3 partitions, one for the OS of 15.32 GB and has 46% free, the second with 110 Gb with 98% free and the third with 110 Gb with 99% free, partitions are NTFS. I have 200 active email accounts, and I have configured a domain and 8 subdomains on the server. |

| Hi BetyG, I usually like to give the OS drive as much room as possible. A few things can cause the system to swap out more than it should and could effect performance. I have attached a PDF file for performance tuning. It is a draft of a document I was working on a while back. It was written for Windows XP, however most of it applies to new OS's. I have used it on my Win 2003 servers, & Windows 7 Workstations. The biggest improvement would be to make a fixed size swap file and defragment the drive. The document mentions a backup program.. ah.. I never finished the document, however I was referring to DriveImageXML from Runtime Software http://www.runtime.org/driveimage-xml.htm. The best part of this software is that it is free. Back to the CPU issue. Do you have any add-on's running with AgGo, such as MailFilter Pro, eWall or any other such programs? Is there any connections happening during these periods of high CPU usage? I just upgraded to 1.0.7.3 but I have not yet noticed any issues. I also close the GUI when not in use for changing settings or when managing accounts. |

|  | | Mail Server v1.0.8.3 |
- Added support of STARTTLS (STLS) command for SMTP, POP3, IMAP, and SMTP relay and delivery, which will
allow secure, fully encrypted connections, when possible;
| | 11/6/2011 1:10:34 PM |
| Mail Server v1.0.8.2 |
- Optimized delivery speed. In earlier versions each "tick" which was checking whether messages were
in the outbox queue, was picking up only one message at a time. Now it will attempt to pick MaximumAllowedThreads-ActiveDelivery threads
messages, which should considerably increase deliver speed;
- Optimized SEARCH and STATUS IMAP commands. They appear to be used very extensively by Android, and (not that extensively, but still) by
iPhone. Now users who use mobile phones to access their IMAP accounts will see considerable improvement;
- Optimized STORE IMAP command. Before storing of IMAP flags was occuring one message at a time, which seemed to be fine
with SQL server, but proved to be slow for SQLite... Now it happens with single SQL call.

| ArGoSoft Mail Server v1.0.8.1 | -
Fixed a bug: when using IMAP via Firefox with "When I delete a message, move it
to Trash folder" option, marking messages in the trash folder was causing high CPU usage,
and was taking some time, making the server pretty much non-responsive. The problem was
happening only when using SQLite.

| ArGoSoft Mail Server v1.0.8.0 |
- Fixed a problem with web interface - was showing only first page of messages, and would not
switch to other pages; In order to fix the web interface, mail server itself has to be updated;
- When installint initially, was still using SQLite, even when SQL was requested;
- There was a problem with switching from SQLite database engine to SQL server database engine:
the SQL database was not being created;
| | 5/23/2011 5:53:55 PM |
| ArGoSoft Mail Server .NET v1.0.7.9 |
- The server no longer requires Microsoft SQL Server. If SQL server is not found, it will use
SQLite engine, which does not require separate installation. If SQL server is found, then user will be
prompted whether he wants to use it;
- Made other improvements, such as, now mailbox rebuild indexes orphaned records, rather then deleting them,
also added an opotion to increment UIDL validity of folder (both on the Mailbox viewer box);
- Made minor improvements on web interface;
