Do hosting providers support IMAP?

Most hosting companies provide POP3, SMTP and IMAP. You can access your imap account using the same settings you would for a regular pop account. (mail.yourdomain.com) Just make sure your firewall isn't blocking port 143.

Can I make multiple IMAP connections to the same address?

No, you can only make one connection to an email address at a time.

I want to save my sent email using Outlook or Outlook Express to the server.

Based on my deep research, due to limitations of the IMAP protocol, as well
as for efficiency and interoperability concerns, Outlook does not allow non
e-mail folder storage on an IMAP server. This means Your Sent Items,
Drafts, and Deleted Items folders cannot reside on an IMAP server. Outlook
requires that all special folders exist in the default store. This is a by
design feature of Outlook and this design is based on the limitation of the
IMAP protocol. I am very sorry to say there is no a direct solution to this
issue.

As a workaround, I suggest that you use the Rules Wizard to save sent
messages in a folder on the IMAP server. You may want to disable the
options to save sent messages in your Sent Items folder. If you do this,
you will keep sent messages from being saved on the local PST folder.

Thank you for your understanding.


You could also use Mozilla Thunderbird which does support this feature.
