sendmail storage...
Instead of a database, can sendmail use regular Unix files for storage?
Thanks in Advance

Re: sendmail storage...
Normally sendmail *is* using regular Unix files: the queue for outgoing mail is located in /var/spool/mqueue and the users' inboxes are in /var/mail in HP-UX.
The use of a database for mail storage is definitely a non-default configuration.
Or did you mean the storage of /etc/mail/aliases and other configuration files? As those may be looked up each time a piece of mail must be delivered, and those files usually won't change all that often, the database or hash maps are used to make the look-up more efficient.
In a high-volume mail server, you would definitely want efficiency.

Re: sendmail storage...
the result of Matti's post:
The pure mail message is stored in plain files.
The (N)dbm format is used to hash stored values.
Addresses/Aliases/... are stored in files of such type; look at that man page:

Re: sendmail storage...
sendmail uses files. Various clients like squirrelmail and Exchange can read these files and put the data into databases.
I'm guessing you don't have a standard installation there.
