I have configured RoundCube to use the PHP mail() function by leaving the $rcmail_config['smtp_server'] value empty.

When I attempt to send a mail RoundCube returns a message indicating that the mail could not be sent. On checking the logs of my mail server I have noticed that the sender's email address is being suffixed with an extra ">". This is the entry in my mail log:

"RECEIVED: MAIL FROM:< John Woods john.woods@strethill.co.uk>" --- notice the extra character

In addition the recipients mail address show the same problem but only when the address is copied from the address book. Here is log entry:

"RECEIVED: RCPT TO:<John Woods john.woods@axa-im.com>" --- again notice the extra ">"

A manually entered recipient address is a handled correctly.
