Some Doubts about Linux Mail Server

Hi Friends,

I have installed Mail server in RHEL-5

Incoming mails: DOVECOT
Outgoing Mails: SENDMAIL

This two service i have installed in Linux RHEL-5, and configured client in outlook express in windows machines, its working fine, incoming and outgoing mails in clients...everything is fine till now,

Now i am having some doubt about MAIL SERVER

1. Client Mails (Incoming & Outgoing) will save in Server?
2. If Yes, Then where it will save the mails?
3. If No, Then is there any option to save the client mails in server end? and how?
4. How to maintain Mail Server, I am newly for this....

Note: I have checked in /var/mails/username_file, here created some files in username, but in this file there no mail which mails clients are sending and receiving...and also have checked in /home/user1/mail or /home/user1/mail/.imap/INBOX here also not available that client incoming/outgoing mails.

Thanks and Regards,
Sandeep CC

Dovecot does NOT do "incoming" mail, that's Sendmail too. think of it more that SMTP is for PUSHING mail between mail servers, (SMTP to SMTP is outgoing mail on the first to incoming mail on the second) whereas an IMAP / POP3 service is for PULLING mail to a client.

1. yes
2. depends, by default sendmail uses mbox format, usually under /var/spool/mail/<username>
3. Note that IMAP servers typically remove mail from the server, pop3 remotely views it, but this behaviour is configurable.
4. well that's a lot of stuff, in terms of smtp, you'd do well to ensure your dead letter queues and mail spools are not getting filled up etc.
