Well, i got some time last weekend and started up porting sendmail 8.11.1


First i use SleepyCat Berkely DB in rpm format i find somewhere, may be 
sourceforce ?

I'm actually able to "send mail" (this mail is sent using sendmail+mutt over
cygwin 1.1.6), but sendmail returns 71 after sending mail, i'm not too much sure why.

I got problems with Berkely DB, probably beacuse it is 3.1.17 and sendmail 
8.11.1 works with 3.0 (AFAIK), anyway it isn't now the big problem..
I have commented out #O AliasFile=/etc/mail/aliases on .cf file,
 I will look at this problems, but as i said there are other things first.

The big problem now is Permission/(set)[GU]ID/(get)[GU]ID && file locking issues


There are all syslog messages over a mail transaccion:


---
: eBBGGfG00319: from=pruiz AT oops DOT ip6seguridad DOT com, size=40, class=0, nrcpts=1, msgid=<200012111616 DOT eBBGGfG00319 AT oops DOT ip6seguridad DOT com>, proto=SMTP, daemon=MTA, relay=localhost [127.0.0.1].

: eBBGGfG00319: SYSERR(root): cannot rename(./tfeBBGGfG00319, ./qfeBBGGfG00319), uid=500: Permission denied.

: eBBGGfG00319: to=pci AT myrealbox DOT com, ctladdr=pruiz AT oops DOT ip6seguridad DOT com (1004/548), delay=00:00:11, xdelay=00:00:02, mailer=esmtp, pri=120040, relay=smtp.myrealbox.com. [192.108.102.201], dsn=2.0.0, stat=Sent (OK).
---

The problem fits on deliver.c but now i got no time to look at this. I have been reading about people trying to port sendmail, and this is my initial work, i wish it can be usefull.


Actualy it runs as TrustedUser=Administrator:Administrators, and it's started
from inetd using srvany.exe

I've tried firedaemon (works with ssh and some other things) but i make some
crap with EventViewer output and i can't see syslog output from sendmail
i must use regedit to correct this.. so i don't recomend using firedaemon.

May when other problems are fixed, it can be modified to run as a service 
itshelf like inetd does.

W/o too much to say..
