Hi Rich,

Thank you for your words of encouragement... unfortunately my modifications
have temporarily been put on hold due to other commitments, my birthday and
letting the dust settle allowing myself some time to mule over the input /
feedback I received from everyone here.

So far I've had two attempts at implementing the extra commands:

1) As part of the url. For example: --url pop3://mail.domain.com/list/3
would perform a single list on message 3
2) Using the -X command. For Example: --url pop3://mail.domain.com/5 -X TOP
would return the header for message 5

As far as I remember I only posted patches here for the second and it is
this that I'm using in my own code at present.

I think I've had enough time to mull things over now and I think I
understand all of the points that Dan raised in the last email in the thread
back on the 22nd December ;-)

Fair point...

True... However, if we remove the message id totally from the URL that will
break any existing apps if and when they upgrade to later versions of
libcurl.

> pop3://mail.example.com -X TOP:2:15 # retrieve 1st 15 lines from msg 2

Indeed... Though I do think we can support this as well as for example
pop3://mail.example.com/1 to retrieve message 1 as well.

You will have seen that I've posted a bunch of smtp updates this week so now
that they have been pushed and I'm starting to get back into curl hacking I
will pick this up again and see what I can do over the next few days ;-)

Hopefully I will be able to post an update soon.

Kind Regards

Steve
