Incoming mail server (POP3) and Outgoing mail server (SMTP) names of Hotmail accounts

I have seen that there is  an option 'remove from sever when deleted from items' is listed in Advance tab while clicking on a Gmail account added in WLM using incoming mail sever "POP3". Then, clicking on 'properties after that, on Advance tab.

However, this option is not found in Hotmail accounts added in WLM using POP3, and Gmail account added on WLM using incoming mail sever "IMAP", Even although the advance tab is available in the second(Gmail accounts added with IMAP). 

Also, there is neither an incoming mail server name nor outgoing mail sever name shown in the sever tab on the Hotmail accounts added in WLM (first screenshot below)

However, for all Gmail accounts, there are(second screenshot below).

Then when should I use these incoming and outgoing mail sever name of Hotmail accounts available below. In other words, where will I be benefiting from these severs as long as I didn't set them via setting a Hotmail account in WLM?

Any comments would be highly appreciated.
