Foreign character in username making emails fail

[CTXMedia]

Getting these in my server error log in XF 1.1.1 - Zend_Mail_Transport_Exception: Unable to send mail. - library/Zend/Mail/Transport/Sendmail.php:137

Which seem to be all to the same user: bobcolover\ <--- note the backslash on the username

Firstly, could someone confirm if they've seen similar issues when someone includes a foreign character in their username?

Secondly, can we define only alpha-num characters for username?

Thanks,
Shaun

Yep. See this thread:

Secondly, can we define only alpha-num characters for username?

Yes:

Admin CP -> Home -> Options -> User Registration -> User Name Match Regular Expression

This regex will match only alphanumeric characters:

^[a-zA-Z0-9]+$

Excellent, thanks again Jake.
