# is the comment character for the ini file where Mercury stores a lot of its settings. This means that the # itself and anything after that on the line will be considered a comment rather than part of the password.

I'll bring the matter to David's attention and we'll see if there is some easy solution.

I beat around the bush for a couple of hours and finally discovered that for the MercuryC SMTP Relay Client, I could not
login with my gmail password because it contained a '#' character. That character and all after it were not saved in the config.

In the end I went and changed my password at Google. Vuela! no more 'Username and Password not accepted' errors!

This post to see if others had/have similar problems. This seems to be some kind of bug. No '#' character in a password?!
I can't be alone with '#' in a password. I just tried !,&,* and they all work. But still not '#'. Save the config, restart Merc and
you lose all p/w characters starting at '#'.
