Hi,
I wonder if there are any (in)official rule - or if not - what you think about is the best
way to format the email addresses of your customers in your company.
[Testperson]
Firstname: Bob
Lastname: Smith
Possible ways are :
#1 bobsmith[at]domain.com
#2 b.smith[at]domain.com
#3 b.s.[at]domain.com
#4 bs[at]domain.com
#5 bob[at]domain.com
#6 bob_smith[at]domain.com
Any ideas / thoughts about this ??

Personally, I would tend to
#1 because I think it gives business communicatiosn a more
personal touch if you add your firstname.
