I've setup a new gmail account
firstname.lastname@example.org in order to use the gmail client to manage email from another account,
I'm receiving all e-mail that's sent to
email@example.com in my
firstname.lastname@example.org mailbox. Great.
However, I'm not able to "send mail as"
email@example.com when using the
firstname.lastname@example.org account. I added the
email@example.com in the "send mail as" options, configured it like my colleagues here at the company (SMTP server, port 587, TLS), and I got the message that an e-mail had been sent to
firstname.lastname@example.org. I tried resending the e-mail confirmation a zillion times using various different settings, but I never get that e-mail at the
Here is a screeshot of the "Save Mail As" settings:
After struggling for a while I noticed the following message in the
email@example.com Spam box:
Delivery to the following recipient failed permanently: firstname.lastname@example.org Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain company.com.br by company.com.br. [188.8.131.52]. The error that the other server returned was: 550-Verification failed for <email@example.com> 550-Previous (cached) callout verification failure 550 Sender verify failed ----- Message suppressed -----
What exactly is going on there? I'm having a hard time interpreting this error message.
ps: I replaced my username with 'me' and the company name with 'company'.
