Calibre GMX Issue

[wagon]

I'm unable to send a book via gmx. From the test email function:

Traceback (most recent call last):

Unfortunately, the link doesn't specify which part of the header doesn't conform: https://postmaster.gmx.net/en/error-messages?c=hd#hd

My calibre version is 4.6.

Thanks.

I just tried GMX works for me. Maybe a temporary server issue, r perhaps a geographic restriction. Try another email provider, such as hotmail.

The link to GMX in the installation leads to gmx.com which does not appear to be for the same purpose. It offers mailcheck for chrome. Just wanted to let you know!

Ignore me, it looked spam like at first but it does allow.

Have you enabled SMTP on GMX? Basically, you need to enable POP3 & IMAP before you can use SMTP. A 554 error is often a "No SMTP server found" error. Check Settings => POP3 & IMAP.
