in the FROM parameter, when i send one mail to a recipient (nameFrom = "nameContact"', adresseFrom ="name@server.fr)

The first time is ok, but the seconde time, the name is duplicated when i receive the mail:

nameFrom = "nameContactnameContact"

The thid time is :
nameFrom = "nameContactnameContactnameContact"

Thanks for reporting this problem, please download easendmail 5.1.0.2 from our site, it fixed this problem.
