If you clicked my profile, you can know that my e-mail account registered in Codeforces is `iDOLM@STER.life`, which is both valid(according to RFC822) and quite **exotic**. (I personally like that term where I got response from [SPOJ Forum](http://discuss.spoj.com/t/not-valid-e-mail/8946), when I said that their system cannot my valid e-mail address.)↵

You might feel some anime addict bought a strange e-mail address, and yes it is.↵
↵
I think that some of system do not see this as valid e-mail address, most of reason is that `life` contains 4 character, which makes lots of inconvenience situation to me.↵
↵
For example, my university mail system is configured to receive mail only matching regex `/^[0-9a-zA-Z]([-_\.]?[0-9a-zA-Z])*@[0-9a-zA-Z]([-_\.]?[0-9a-zA-Z])*\.[a-zA-Z]{2,3}$/i`, which cannot accept e-mail address containing `+` character, `life` domain, and so on.↵
↵
I think I cannot receive an e-mail including Codeforces. My another email account `sakura@kyouko.moe`, equally configured with `idolm@ster.life` can receive mail. I did not noticed it quite long, but once I tried to log in polygon, it says me to check e-mail inbox, and I cannot receive an e-mail. (Sure, I checked a spam mail box)↵

I just want to ask Codeforces to check this issue, and if you are developing e-mail-related system, just want you to think a little about weird anime addict using exotic e-mail address using `iDOLM@STER.life`. (You can use RFC822 standard anyway)↵
↵
UPD: I think issue in codeforces was fixed. Thanks in advance.
