Nope it wont do it from snort alerts, but you could use this as a
solution, since you have a time stamp of the snort alert you could then
know where in the log of mail that's being generated by ettercap to look
and since you know what word you are searching for its even easier. Just
pointing it out as a tool to help get the job done.

Yeah, there are several programs out there that log SMTP traffic.
Mailsnarf comes to mind. They all require you to sniff and feed the
program though. 

Or are you saying that Ettercap can read in data from Snort logs? (not
tcpdump).

It shouldn't be too hard to write a shell script that parses the Snort
log file, grabs the hex values out and writes it as ASCII to a file (and
then maybe change the To: header and re-insert it into your MTA of
choice). 

Would be nice having as a plugin though.
