one of those might get through, but the others'll end up in the default users account who, if he checks it, will probably mention it to the intended user and all that makes you look a little less pro.
you're better off finding out the standard syntax that they use. if there's even one or two addresses on the site that should tell you right off whether to use first initial, last name, first name dot last name, etc.
even if they have one of those annoying sites that only allows contact through a submitted form you should at least check the WHOIS to see if theres a NAME listed at that domain (as opposed to
admin@*.com)
if you dont have any luck there just Google for '@domain.com'. Anybody there thats ever put their email address in a press release, forum posting, etc will be listed and you can get the syntax from that.
oh yeah. social engineering always works the best. didja think of calling the receptionist and asking? theyre usually just as happy (or unlearned) to give out that as they are to send you directly to somebodys voicemail when you wanna leave one of those "i tried to reach you, guess you're out of the office, thanks for last night" messages.
