Please do not hide information that could be important to helping you solve the problem.  That IP address and the timeout setting is critical and no security risk at all.

That said,  I would first increase the timeout and see if that fixes the problem.  Also if you have AVG between Pegasus Mail and the POP3 server I would remove that as well.  If neither of these fixes the problem then you probably have some sort of packet fragmentation problem.   The POP3/SMTP transmissions may fail if the MTU packet size is so large that a packet is fragmented.  In many cases the receiving system router blocks the receiving servers "packets fragmented" response to the sending system using "MTU Discovery".  These oversize packets are not accepted and so are resent.  This results in a timeout, generally at the end of the message transmission but it can be anywhere in the process.  You need to reduce the MTU size. Windows defaults to a 1500 MTU and many routers and DSL connections need 1492.  You might simply want to turn off the MTU Discovery operation.

You might want to get a copy of SG TCP Optimizer that I find quite handy.  http://www.speedguide.net/downloads.php  This little utility will allow you to test your MTU for maximum size without fragmentation against specific servers.  If will also make it easy to adjust the MTU.  

And finally, does this computer, by chance, happen to have an NVidia NForce 4 chipset on the motherboard?  If so, many other have had this exact problem, and it turned out to be an optimization setting for the built in NIC which caused the problems with packet fragmentation. Disabling the advanced optimization capability called "checksum offload" made all the problems of sending SMTP mail via WinPMail disappear.

Dear sir, madam,

I use Pegasus V4.30 beta to send e-mails. I've got Avast antivirus and use Windows XP. I installed a webcam at my machine a few days ago.

I've got now problems in sending e-mails. In the left screen you can see...SMTP:sending message 1 of 1 ...4%

The message I get is:[*] Connection established to (number IP)

>> 0055 220 ESMTP smtp-out1.tiscali.nl. NO UBE/UCE tolerated.
<< 0021 EHLO [192.168.1.33]
>> 0064 250-smtp-out1.tiscali.nl Hello [IP] [IP]

8: Socket read timeout.

I did change IP in the file - there is a number mentioned 

But I'm sending not an email with attachment....

After this message another one has been sent to mine e-mail:

Delivery has failed on the enclosed message for the following
reasons reported either by the mail delivery system on the mail
relay host or by the local TCP/IP transport module:

   *** TCP/IP error while processing job ***
   A network error has occurred while WinPMail attempted to send
   your message. This error could be caused by many conditions,
   including the following:
     * The remote host may have gone down.
     * Your network may have been broken or gone down.
     * You may have a configuration problem in your WINSOCK.DLL.
     * If running on a SLIP line, you may have experienced a
       timeout (increase the value in WinPMail's Network Config.
       Dialog), or the phone line may have gone down or suffered
       from excessive line noise.
   WinPMail will requeue your message and try again later.

The advanced settings are on demand... so could you please give some instructions for help?

Thanking you in advance,

Sylvia Schencke
