[quote user="rpk2006"]Oh sorry I erased the error description. It displays: "Connection Time Out", even when it internet is ON and it has successfully downloaded the few. In the error window, after scrolling down it displays: "Socket Timed Out".[/quote]

Increase the Timeout on Tools => Internet options => General and on the POP3/SMTP definitions for the respective connection.

You didn't say it crashed in your first post, just that an error occured? And, BTW, that's one of the issues that selective download is for: If any single message causes Pegasus Mail to fail you can download only a couple of them manually to figure out which one causes trouble without Pegasus Mail reloading the same messages over and over again.

And an addition with regard to filtering: You may apply each filter manually to any folder via Tools => Mail filtering rules => Apply general rule set to folder after doing selective downloads.

And if you really encounter a crash: Please consider using my MiniDump extension for providing debugging details for David Harris.

I created three folders in my default Mail folder to filter our mails. I have created the filter rules also.

Each time I check for mails, Pegasus just fills those three folders with duplicate mails. The mails that it had already downloaded before. The total mails on my server are 333. Each time I start Pegasus, it starts downloading from 1, but it never completes downloading. When it reaches say, 15 or 17, it displays an error (see the attached image).

It is filtering properly, but in each folder it is creating duplicates. Each downloaded message has 3 to 4 copies.

Mails are only marked as read or deleted from the server if Pegasus Mail successfully finishes the download. Use Selective mail download from the File menu for downloading these 15 or 17 messages (filters will be ignored), then try again your filtered download. BTW: You cut off the interesting part of the connection trace, you should have scrolled down to the end before taking the screenshot for showing what actually caused the error.

I really want to use Pegasus Mail, but I think it is very complicated.
