"Send trough gmail" is gone for new e-mail aliases

Having aliases handled through gmail is very convenient, but there is a change now, where you need to supply an SMTP server for each alias you register. This complicates things quite a bit. I now have to get hold of an SMTP server for a mail alias ASAP.

If you try to specify Gmail's own SMTP server, Gmail will check that server as a part of the form validation process, and Google will classify its own check as a hacking attempt targeting your account. At least that's what's happened when I tried, so it's probably better to use another SMTP server.

It seems like previously registered aliases still work and do not suffer from this. Be careful if you edit them though....

 

Now, Google has removed the option to send through their servers and we must specify the SMTP settings for our hosting provider’s server in order to send email as this address. Google has helpfully entered a best-guess of what the servername might be, but you’ll still have to check with your regular hosting provider to get the proper setup information.
