Is this 100% safe in conjunction with SPF?
Sending an mail through tempalias leads to a SPF failure since tempalias.com isn't allowed to send mails in the name of the sender's domain. If the receiving mailserver doesn't accept mails with failed SPF check, the mail will be discarded.

And IMHO it's a bad idea for SPF to use the message headers instead of the envelope to do validation as that leads to issues not only with services like tempalias, but also mailing lists for example. This is also why SPF failures usually are not treated as enough reason to discard an email.
