Hi

What mail server can prevent incoming mail to repeat downloading to the mail client?

Thank you for your help

It is usually up to the client what they want to download, how many
times they do it (a user may have different clients and may reconfigure
them to drop and re-add an account, etc.), and when they delete from the
server. I'd be surprised if any servers strictly limit repeat
downloads. On the other hand, any sensible mail client will track the
messages it already has and not download them again. If something is
doing it repeatedly it is probably broken.

Here's one example: me. When I'm not at home, I read my email via webmail.
I could, I suppose, d/l it *without* deleting from the server. Then, when
I get home, I fire up t-bird, and d/l all my mail, this time deleting it.

I might assume that some folks d/l frequently, but do not delete from the
server, thus saving space on their own system, but storing everything on
the server.

What mail client are you using?

My people use Thunderbird, it keeps track of the emails that it has
downloaded and doesn't download again...

I had this problems years ago with earlier versions, but only at random
and on different clients and at different time, it was unrepeatable..

Most pop3 servers will start from the beginning of a mailbox; if the
last download of mail was not completely successful (from start of
mailbox to end of mailbox), you get the situation you describe if I
understand your comments.

e.g., a customer on dialup that receives a 10 MB email message, can't
download it, and tries again.

It's possible that the client is having trouble downloading one particular
message and that's causing it to repeat all the downloads (this used to
happen a lot with pop-3 clients). Find and delete the offending message and
the problem should be solved.

Are you talking about IMAP or POP3 - they behave differently. With POP
each client location has to download and choose to keep original on
server, otherwise only one client can see the email. With IMAP one has
the option to see the headers and by default leaves the server as the
master. This does put more traffic on an IMAP server as a rule, but I
use IMAP in preference if possible so that I can access emails via my
iPhone and my T-bird clients, but only deal with mail once.

I use a service from www.fusemail.com. It's worked quite nicely for my and our
small company. I've setup multiple email accounts and they all gel pulled
into the same inbox at my fusemail account. I've setup multiple folders and
rules to segregate the various email accounts, mailing lists, etc. I use an
IMAP connection for my mail client, so any actions I take on the web interface
(away from my laptop) such as deleting emails, creating new folders, etc are
automatically reflected in my mail client (in my case Kmail) the next time I
connect. Thus, if I delete messages from the web interface then my mail client
never tries to download those same messages, and if my client has already
pulled them then they simply disappear on the next check.

Yes, if the client in question is using pop, switching to imap is
probably a good idea. There is an option in tbird (and probably others)
for whether to download all the messages or wait till you read them.
