headers of address parser functions
| int addrparse |
( |
char * |

|
|
const int |

|
|
string * |
addr, |
|

| |
check an email address for syntax errors and/or existence
- Parameters
-
| in | input to parse |
| flags |
0: mail from checks 1: rcpt to checks (e.g. source route is allowed)
|
| addr | struct string to contain the address (memory will be malloced, is set if 0 or -1 is returned) |
| more | here starts the data behind the first '>' behind the first '<' (or NULL if line ends after the '>') |
| ds | store the userconf of the user here |
| rcpthosts | array of the valid rcpthosts |
| rcpthsize | size of rcpthosts array |
- Returns
- if address was validated
- Return values
-
| 0 | address exists locally |
| >0 | on error (e.g. ENOMEM, return code is error code) |
| -2 | if address not local (this is of course no error condition for MAIL FROM) |
| -1 | if address local but nonexistent (expired or most probably faked) OR if domain of address does not exist (in both cases error is sent to network before leaving) |
ds may be NULL in case the result is not interesting (e.g. if only checking MAIL FROM).
| int addrspec_valid |
( |
const char *const |
addr | ) |
|
check if the given string is a valid addr-spec
- Parameters
-
- Returns
- if string is valid addrspec
- Return values
-
| 0 | string is invalid |
| 1 | string is valid |

check an email address for syntax errors
- Parameters
-
| in | address to parse |
| flags |
0: mail from checks, 1: rcpt to checks (e.g. source route is allowed), 2: checks for badmailfrom/goodmailfrom lists
|
| addr | struct string to contain the address (memory will be malloced) |
| more | here starts the data behind the first '>' behind the first '<' (or NULL if none) |
- Returns
- >0 on success
- Return values
-
| 1 | address is empty (only possible if flags is 0) |
| 3 | address is a full email address |
| 4 | address is a full email address with IPv4 or IPv6 address literal |
| 0 | in is invalid |
| -1 | an error occured (e.g. ENOMEM) |
| int checkaddr |
( |
const char *const |
addr | ) |
|
check an email address for validity, use as loadlistfd callback
- Parameters
-
- Returns
- if address valid
- Return values
-
| 0 | address is valid |
| 1 | address is invalid |
This is just !parseaddr(addr). This allows this to be used as callback.
| int user_exists |
( |
const string * |
localpart, |
|
|
const char * |
domain, |
|
|
struct userconf * |
dsp |
|
) |
| |
check if the user identified by localpart and ds->domainpath exists
- Parameters
-
| localpart | localpart of mail address |
| domain | domainpart of the domain |
| ds | path of domain |
- Return values
-
| 0 | user doesn't exist |
| 1 | user exists |
| 2 | mail would be catched by .qmail-default and .qmail-default != vpopbounce |
| 3 | domain is not filtered (use for domains not local) |
| 4 | mail would be catched by .qmail-foo-default (i.e. mailinglist) |
| 5 | domain is not local |
| <0 | error code |
If the user has it's own mail directory ds->userpath will be filled with the correct values.
This function must be implemented by the password backend (i.e. currently vpop.c).
