Can anyone guess why sendmail (uk, 1.4a) on a SUN (os 3.5)
might botch the following ...
a) mail arrives from outside (JANET); addressed to non-existant user here
b) sendmail tries to reply to the sender
c) IFF the sender has dots in his/her name (eg some.body@somewhere) , the
address seems to get spaces put around the "@", so that there are now three receipients;-
1) some.body
2) @
3) somewhere
All three are treated as local users and only (2) is valid
(it is an alias for postmaster, thank god!)
here is a snippet:-

| c) IFF the sender has dots in his/her name (eg some.body@somewhere) , | the address seems to get spaces put around the "@", so that there are | now three receipients;- I used to get a similar problem with our EMAS machine... it would send messages that had originator fields like From: Some.Body @ uk.ac.edinburgh with spaces in the address. Sendmail would generate errors to "Some.Body", "@", and "uk.ac.edinburgh" Your problem sounds the same. I fixed mine by changing the "o" option as follows: # DO NOT default messages to old style - comma delimiting only. OoF Only commas will seperate addresses in address lists now. I have not noticed any problems with doing this. Scott Larnach
