SM-S-2 SMTP local mailer

Storing incoming mail into the DataBase

Installation instructions

The Virtuoso server can store the incoming mail into the database using it's own local mailer implementation. The following sections detail the configuration of each type of mail environment.

Replacing procmail as default handler in sendmail configurations

```
Copy virt_mail to /usr/bin/virt_mail
Copy odbc_mail.default.ini to /etc/odbc_mail.ini
```
IMPORTANT: Make sure /etc/odbc_mail.ini is NOT GROUP/WORLD writable, otherwise virt_mail will fail to run.
Edit /etc/odbc_mail.ini and change the login settings to match your current database installation. If you don't have or want to use procmail, comment out the "Fallback" setting in the [Deliver] section.
Edit /etc/sendmail.cf. Change:
```
  Mlocal,	P=/usr/bin/procmail, F=lsDFMAw5:/|@qSPfhn9, S=10/30, R=20/40,
		  T=DNS/RFC822/X-Unix,
		  A=procmail -Y -a $h -d $u
```
into:
```
  Mlocal,	P=/usr/bin/virt_mail, F=lsDFMA5:/|@qSPhn9,
		S=10/30, R=20/40, T=DNS/RFC822/X-Unix,
		A=virt_mail -c /etc/odbc_mail.ini -l $u -s $g
```
NOTE: The changes to the F= setting involve removing both the 'w' and 'f' flags. The removal of the 'w' flag affects lookups in /etc/passwd, which are no longer required if all mail drops go into the database. The default ini file is set up to maildrop to procmail, which will perform this check correctly.

Per-user database maildrops under sendmail

```
Copy odbc_mail.default.ini to ~the_user_name/.odbc_mail.ini
```
IMPORTANT: Make sure the .odbc_mail.ini is NOT GROUP/WORLD writable, otherwise virt_mail will fail to run.
Put at the end of ~the_user_name/.procmailrc something like:
```
:0:
| /usr/bin/virt_mail -c .odbc_mail.ini -l the_user_name
```
replacing the_user_name with the user you're setting up. Note: the '-l ..' parameter is used to relate the local recipient to the database user for which the maildrop is done. See the remarks in the odbc_mail.default.ini file.
Adjust the parameters in .odbc_mail.ini to match your configuration IMPORTANT - also disable Fallback delivery in .odbc_mail.ini Comment out the "Fallback =" entry in the .odbc_mail.ini or set it to something that doesn't involve procmail. Otherwise, this could lead to drop loops.

Per-user database maildrops under qmail

```
Copy odbc_mail.default.ini to ~the_user_name/.odbc_mail.ini
```
IMPORTANT: Make sure the .odbc_mail.ini is NOT GROUP/WORLD writable, otherwise virt_mail will fail to run.
If you're setting up a .qmail, simply do something like
```
| /usr/bin/virt_mail -m qmail -c .odbc_mail.ini
```
If you're setting up .qmail-default or .qmail-<some_alias_name>, make sure you adjust the RemovePrefix accordingly in the odbc_mail.ini. This also works if a single user is receiving mail for an entire (virtual) domain. If you want to configure qmail so that user 'db' gets all mail for example.com, do this:
1. Create a new user db in /etc/passwd etc.
2. Remove example.com from /var/qmail/control/locals
3. Add to /var/qmail/controls/virtualdomains:
```
example.com:db
```
4. Adjust /var/qmail/users/assign accordingly:
```
	=db:db:<uid>:<gid>:<home>:::
	+db-:db:<uid>:<gid>:<home>:-::
```
  or run
```
qmail-pw2u < /etc/passwd > /var/qmail/users/assign
```
  then run qmail-newu and restart qmail
5. In ~db/.qmail-default, put:
```
| /usr/bin/virt_mail -m qmail -c .odbc_mail.ini
```
6. In .odbc_mail.ini, set RemovePrefix=db- Now, mail to info@example.com will be delivered to the qmail alias db-info@example.com and is stored into the database for user 'info'.
Adjust the parameters in .odbc_mail.ini to match your configuration

Per-user database maildrops under courier

```
Copy odbc_mail.default.ini to ~the_user_name/.odbc_mail.ini
```
IMPORTANT: Make sure the .odbc_mail.ini is NOT GROUP/WORLD writable, otherwise virt_mail will fail to run.
If you're setting up a .courier, simply do something like
```
| /usr/bin/virt_mail -mcourier -c .odbc_mail.ini
```
If you're setting up .courier-default or .courier-<some_alias_name>, make sure you adjust the RemovePrefix accordingly in the .odbc_mail.ini. Note 1: Although courier is very similar to qmail in this respect, it is different from qmail in how it handles exit codes. If you use -mqmail while running under courier, you'll get the wrong exit codes, so mail is bounced instead of retried. Note 2: If delivering to multiple recipients in a .courier file, make sure the virt_mail is specified first. This is because if the virt_mail fails with a temporary error, the other recipients will get another drop when courier re-attempts to deliver the mail. Right:
```
| /usr/bin/virt_mail -mcourier -c .odbc_mail.ini
./Maildir
```
Wrong:
```
./Maildir
| /usr/bin/virt_mail -mcourier -c .odbc_mail.ini
```
Adjust the parameters in .odbc_mail.ini to match your configuration

EXIM

Here are code snippets for Exim that perform maildrops into the odbc database.

## IN TRANSPORT SECTION

# Delivers into the database
odbc:
  driver = pipe
  command = /usr/bin/virt_mail \
	-c /etc/odbc_mail.ini \
	-s "${if def:return_path{$return_path}{MAILER-DAEMON}}" \
	-l "$local_part"
  user = USERNAME
  return_path_add
  delivery_date_add
  prefix =
  suffix =
  temp_errors = 73 : 74 : 75
  return_fail_output

# NOTE: Make sure the USERNAME in the 'user = USERNAME' setting matches
# the owner of /etc/odbc_mail.ini, because this file must have mode 0600.
# Consider creating a new user account for this delivery only.
# You should specify 'user = root' here only if Fallback delivery is
# configured in /etc/odbc_mail.ini (for procmail fallback delivery
# for instance)


## IN DIRECTORS SECTION

# Attempts delivery of all mail into the database
to_db:
  driver = smartuser
  transport = odbc
  require_files = /etc/odbc_mail.ini
  #
  # uncomment line below to deliver all mail to db-XXX into the database, for any
  # value of XXX. For this to work, set "RemovePrefix = db-" in
  # the [Translate] section in /etc/odbc_mail.ini
  #prefix = db-
