T-Online provides various incoming mail servers for checking the emails. Before you activate SSL, check here which server you are using and set the correct outgoing server. Below you will find an overview of the configurations:
- If you are using popmail.t-online.de as your incoming server, please change the outgoing server to smtpmail.t-online.de.
- If you are using pop.t-online.de as your incoming mail server, please change the incoming mail server to securepop.t-online.de and the outgoing server to securesmtp.t-online.de.
- If you use imapmail.t-online.de or imap.t-online.de as incoming mail server, please change the outgoing server to smtpmail.t-online.de.
- If you use securepop.t-online.de or secureimap.t-online.de as incoming mail server, no changes are necessary, since encryption is already activated for you.
Additional settings for SSL encryption
After you have checked the data of your incoming and outgoing server, click on the "Further settings" button and switch to the "Advanced" tab. Enter the following there:
- Incoming server (POP3): 995 or incoming server (IMAP): 993
- Outgoing mail server (SMTP): 465
