Retroactively, perhaps not.
You need to have the server logging set to show connection source and count.
Ex (watch out for MUA line-wrap):
2007-03-09 16:21:59 SMTP connection from [193.17.85.216]:3822
I=[203.194.153.81]:25 (TCP/IP connection count = 2)
If it is being logged, exigrep or plain-old-grep on 'connection count', then
look for the time/date of the peaks, go back in on the time-date and find the
rejections.
Or something like that.
log_selector = +all provides that detail and a lot more, or you can pick and
choose with + and -. Copious specifics in the docs.
