Re: [twsocket] TPop3Cli is halted while receiving a message over 4Mb
Theres a very good, and free one called Analyzer that uses WinPCap. There used to be a link from the winpcap page, not sure if its still there.

If you want a free one, look at Ethereal (link on the links page at my website). Oh! Its size is 11Mb. I'd prefer to not download and install such a big thing. I installed WinPcap and tried to use Magenta Systems Monitor Socket, but it shows AV (nil is dereferenced, I presume; adapter listbox is empty) at the start though continues to run. Nevertheless it does not capture anything ;-(. I don't see any pages on http://www.magsys.co.uk/ , which are related to the program. Perhaps, a newer version is available somethere. A sniffer peek data packet on the network cable without interfering with applications. It works at the NDIS driver level, asking the driver to receive a copy of each packet sent/received.

You cannot do anything if the the server does not sent the end of message marker. Quoted from the RFC's: When all lines of the response have been sent, a final line is sent, consisting of a termination octet (decimal code 046, .) and a CRLF pair.

Except waiting for a timeout and handle it.

Re: [twsocket] TPop3Cli is halted while receiving a message over 4Mb
(taking into account that they disclose themselves in such a negligible, infrequent manner)? Do you mean that it doesn't always occur with the same 4MB message ? Yes. Today the program fetches the same message (it remains on a server) successfully (several times for testing). Now I can't investigate the matter, alas.

Today the program fetches the same message (it remains on a server) successfully (several times for testing). Then it is most likely due to a bad line to the server/internet. You should implement a custom timeout that triggers when the server didn't send a packet/line within let's say 60 seconds. Or try a sniffer to check what's going on.
