Mail Server query

Hi

Our mail topology is this;

Application servers > Sendmail Mail Relays > Internet
                                        v                                      
                                   Exchange


There is no direct connection between our application servers and Exchange. If an application wishes to send email, it has to use the mail relays. We do this because we run so many apps and want to keep our Exchange 'safe' for corporate email only.

We have a new application that can act as a 'mail server'. It needs to be able to send and recieve emails. Sending emails is fine, we just configure the SMTP server: as one of our mail relays.

However, I am a little confused when it comes to receving emails. The server can recieve emails fine, but where will they go? I know in Exchange, they go into mailboxes, is this common for most mail servers? Or do they tend to go into folders?

If not, we can set up a forwarder on the mail relays to direct mail sent To: <application>@server.com to <application@mydomain.com> where mydomain is our Exchange organisation. We would create a mailbox for it. However, if the application server wanteed to talk to Exchange to manipulate/check these mails, does anyone know what port this would be on?

Hi,
If the application is so called "Mail Server", then it should provide you means of collecting/managing mails also. Not sure if your application can do that, it should theoretically.
Also, check the Mail Server will 100% have configuration options for forwarding of mails.
Also, anything to do with mails is by default on Port 25 !!

"Also, anything to do with mails is by default on Port 25 !!"

This is SMTP though isn't it - wouldn't there be a different port if it wanted to retrieve mail, check the content of mail etc?

Retriving mails can be done via many ways....MAPI/IMAP/POP3/Webbased
Depends what your mail server supports.
