Murat, I know it's scary to change the way you think and do things, but it is possible to swap in any of the popular sendmail replacements without interuption to user services. In a previous position, we too were using sendmail with several thousand (nearly 6k) users. We managed to make the switch to postfix with no intruption to service (down sendmail, up postfix, 15 seconds at the most). Postfix, if you'll read the docs, is a drop-in replacement for sendmail, requiring absolutely no migration. Qmail can also be configured as a drop-in replacement for sendmail (it can deliver to mbox style mailboxes).
