SMTP configuration for GMX

  • No replies
  • 0 have this problem

Hello,

I'm trying to setup a new GMX email address in Thunderbird. I can receive messages, but when I try sending an email, I get stuck on the loading bar "sending message". I receive no error message.

I have multiple GMX addresses in Thunderbird already, all work well for receiving and sending emails. I tried writing to email addresses with different providers, the result is always the same.

I tried adding the IMAP info manually and automatically in Thunderbird, nothing changes. Here is my current SMTP server :

mail.gmx.com Port 465 SSL/TLS Normal password

Can someone please help me figure out this SMTP setup ?

Thanks ! Alix
