I can't change my e-mail address from f_philipp@fastmail.net to bugzilla@f_philipp.fastmail.net or bugs@f_philipp.fastmail.net or any other address ending with @f_philipp.fastmail.net. Reproducible: Always Actual Results: Bugzilla doesn't complain, I just never receive the mail to confirm the change (except of the one sent to my old address). These addresses are completely valid and work with gentoo mailing lists and other automatic mail sending systems. Only web sites using regular expressions to check new e-mail addresses sometimes have problems with them. You may send test mails to me. I'll be happy to answer within a day or two.

Thanks, I'll do.
The bugzilla stock regexes were a bit too strict. I added _ in the hostname now. IIRC having _ in the hostname is against RFCs, but is commonly used anyway.
