My original posting -
SUN managers,
I need opinions from experienced sunmanagers on SUN's version of sendmail. 
How secure is that for an Internet-facing SMTP application ? Or is it common
opinion that the opensource version of sendmail ( is generally
more secure ? I know that SUN is always a couple of versions behind but is
that necessarily bad ?
Does SUN offer sendmail just as an "also offered" software or are they
serious about supporting it and quickly patching security holes if customers
have a problem ?

Thanks to all the people who replied. My apologies if i missed someone -

About sendmail - Almost everyone said the same thing.... DO NOT use SUN's sendmail (or any other outdated version for that matter) for an Internet facing  SMTP application. In fact i found something on SUN's website echoing the opinion. -

If you have to go with sendmail then the most recent version (which opensource provides) is the best option.

Alternatives to sendmail -
There was an overwhelming number of people who preferred postfix and/or qmail over sendmail for various reasons like security,ease of configuring and maintaining etc. I would definitely look into these options.

Thanks to the list and everyone who took time to reply.
