SFS_TYPE
Synopsis
The
sendmail program can temporarily fail incoming
mail messages if they are too large for the queueing disk. This
ability is enabled by giving a positive, non-zero size to the
MinFreeBlocks
option (See this section). The method sendmail
uses to measure the free space on a disk varies from system to
system. This SFS_TYPE compile-time macro defines which of several
methods sendmail will use. Those available are
shown in Table 3-11.

SFS_NONE |
Your system has no way to determine the free space on a disk. This

SFS_USTAT |
Your system uses the ustat(2) system call to get information about mounted filesystems. |
SFS_4ARGS |
Your system uses the four-argument form of the statfs(2) system call and <sys/statfs.h>. If you define this, you can also define SFS_BAVAIL as the field name for the statfs C-language structure (by default, f_bavail). |
SFS_VFS |
Your system uses the two-argument form of the statfs(2) system call and <sys/vfs.h>. |
SFS_MOUNT |
Your system uses the two-argument form of the statfs(2) system call and <sys/mount.h>. |
SFS_STATFS |
Your system uses the two-argument form of the statfs(2) system call and <sys/statfs.h>. |
SFS_STATVFS |
Your system uses the statvfs(2) system call. |
In general, SFS_TYPE is correctly defined for all supported systems. You should need to modify it only if you are porting to a new system. ...
