6749632Scael.Sh BUGS
6863451SbosticIf you have compiled
6963451Sbostic.Xr sendmail
7063451Sbosticwith DBM support instead of NEWDB,
71*65102Smckusickyou may have encountered problems in
7249632Scael.Xr dbm 3
7363451Sbosticrestricting a single alias to about 1000 bytes of information.
7420789SmckusickYou can get longer aliases by ``chaining''; that is, make the last name in
7520789Smckusickthe alias be a dummy name which is a continuation alias.
