[SM-USERS] Email delivery error... but message is still delivered.

[Bob J. <bob...@us...>]

Hey all.  I am in the process of migrating mail servers here at our 
organization and have run into a problem with squirrelmail (1.4.8).  I 
have almost everything else working (other than an issue with 
squirrelspell) but have run into one here I can't figure out.

So, I hit the compose link and the compose window pops up.  I create my 
message and hit send.  The message is successfully sent, however at the 
top of the window the following appears:

ERROR:
Email delivery error
Server replied: -1 Can't execute command '/opt/TWWfsw/sbin/sendmail -i 
-t -fb...@us...'.

I don't see anything out of the ordinary in the mail log:

Nov 13 12:30:32 tony sendmail[9571]: [ID 801593 mail.info] 
kADHUWGf009571: Authentication-Warning: tony.bor.usg.edu: www set sender 
to bob...@us... using -f

And permissions on the sendmail binary look good to me:

ls -la /opt/TWWfsw/sbin/sendmail
lrwxrwxrwx   1 root     other         38 Oct  2 10:24 
/opt/TWWfsw/sbin/sendmail -> /opt/TWWfsw/sendmail8134/sbin/sendmail

  ls -la /opt/TWWfsw/sendmail8134/sbin/sendmail
-r-xr-sr-x   1 root     smmsp     909348 Aug 31 17:22 
/opt/TWWfsw/sendmail8134/sbin/sendmail

Any idea what this can be?  I'm not a PHP expert, so I haven't been able 
to delve into the SquirrelMail internals too deeply, but this one really 
has me confused.
