<link rel="canonical" href="https://danwin1210.de/mail/">

<p>Info | <a href="/mail/register.php">Register</a> | <a href="/mail/squirrelmail/src/login.php" target="_blank">Webmail-Login</a> | <a href="/mail/manage_account.php">Manage account</a></p>
<h2>What you will get</h2>
<p>You get a free anonymous E-Mail address and an XMPP/Jabber account using the same details. Your Jabber ID is user@danwin1210.de and can be connected to directly from clearnet or via TOR hidden service (danielas3rtn54uwmofdo3x2bsdifr47huasnmbgqzfrec5ubupvtpid.onion).</p>
<p>You will have 50MB of disk space available for your mails. If you desperately need more space, just <a href="/contact.php">contact me</a>. Your E-Mail address will be user@danwin1210.de</p>
<p>For privacy, please use PGP mail encryption, if you can. This prevents others from reading your mails (including me and/or LEA). GnuPGs official home: <a href="https://gnupg.org">https://gnupg.org</a> Windows GUI: <a href="https://gpg4usb.org">https://gpg4usb.org</a></p>
<h2>E-Mail Setup</h2>
<p>SMTP: danwin1210.de Port 465 (SSL/TLS) or 587 (StartTLS)<br>
IMAP: danwin1210.de Port 993 (SSL/TLS) or 143 (StartTLS)<br>
POP3: danwin1210.de Port 995 (SSL/TLS) or 110 (StartTLS)<br>
Authentication: PLAIN, LOGIN</p>
<p>You can also connect on the same ports via the tor onion address danielas3rtn54uwmofdo3x2bsdifr47huasnmbgqzfrec5ubupvtpid.onion, but you will have to accept an SSL certificate only valid for the clearnet domain.</p>
<h2>XMPP setup</h2>
<p>Domain: danwin1210.de<br>
Connect server: danielas3rtn54uwmofdo3x2bsdifr47huasnmbgqzfrec5ubupvtpid.onion (optional for torification)<br>
File transfer proxy: proxy.danwin1210.de<br>
BOSH URL: https://danwin1210.de:5281/http-bind (only enable if you have to, as it is slower than directly using xmpp)</p>
