Yahoo mail app: can't add my self-hosted mail account reddit / selfhosted ---------------------------------------------------------------------- europacafe · 2023-11-29 04:58 I usually use Yahoo webmail, access via desktop browser, to manage my yahoo, gmail, and outlook mailboxes, in one place. Yahoo mail seems to be the only free webmail that allows me to add multiple mailboxes from different mail providers. ​ As I have successfully hosted my own mail server (docker-mailserver) with my own domain name. I use my self-hosted Roundcube webmail with it without any problem; but Roundcube can handle only one mailbox at a time, so I want to add my new mailbox to Yahoo webmail. ​ The only way to add a new mailbox to Yahoo webmail is via the Yahoo mail app. I've tried it several times without success. ​ When adding a new mailbox with Yahoo mail app, there are 2 steps: step-1: specify my email address ([name@maydomain.com](mailto:name@maydomain.com)), my mailserver imap and smtp server after entering, my mail server log indicated that it is successful ​ `Nov 29 11:19:41 mail postfix/submissions/smtpd[2523]: connect from` [ `sync400374.mail.bf2.yahoo.com`](https://sync400374.mail.bf2.yahoo.com )`[`[`74.6.113.26`](https://74.6.113.26)`]` `Nov 29 11:19:42 mail postfix/submissions/smtpd[2523]: Anonymous TLS connection established from` [`sync400374.mail.bf2.yahoo.com`](https:/ /sync400374.mail.bf2.yahoo.com)`[`[`74.6.113.26`](https://74.6.113.26) `]: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key- exchange X25519 server-signature ECDSA (P-256) server-digest SHA256` `Nov 29 11:19:43 mail postfix/submissions/smtpd[2523]: disconnect from` [`sync400374.mail.bf2.yahoo.com`](https://sync400374.mail.bf2.ya hoo.com)`[`[`74.6.113.26`](https://74.6.113.26)`] ehlo=1 quit=1 commands=2` `Nov 29 11:19:43 mail dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 3 secs): user=<>, rip=`[`74.6.113.153`](https://74.6.113.153)`, lip=`[`192.168.2.202`](https://192.168.2.202)`, TLS, session=` ​ step-2: then Yahoo mail app asked for my email password, this step is not successful: log message from my mailserver: `Nov 29 11:20:04 mail dovecot: imap-login: Disconnected: Connection closed: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher (no auth attempts in 0 secs): user=<>, rip=`[`67.195.177.201`](https://67.195.177.201)`, lip=`[`192.168.2.202`](https://192.168.2.202)`, TLS handshaking: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher, session=` `Nov 29 11:20:05 mail postfix/submissions/smtpd[2523]: connect from` [ `dip192.lsn.bf1.yahoo.com`](https://dip192.lsn.bf1.yahoo.com)`[`[`67.1 95.177.201`](https://67.195.177.201)`]` `Nov 29 11:20:05 mail postfix/submissions/smtpd[2523]: SSL_accept error from` [`dip192.lsn.bf1.yahoo.com`](https://dip192.lsn.bf1.yahoo. com)`[`[`67.195.177.201`](https://67.195.177.201)`]: -1` `Nov 29 11:20:05 mail postfix/submissions/smtpd[2523]: warning: TLS library problem: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher:../ssl/statem/statem_srvr.c:2283:` `Nov 29 11:20:05 mail postfix/submissions/smtpd[2523]: lost connection after CONNECT from` [`dip192.lsn.bf1.yahoo.com`](https://dip192.lsn.bf 1.yahoo.com)`[`[`67.195.177.201`](https://67.195.177.201)`]` `Nov 29 11:20:05 mail postfix/submissions/smtpd[2523]: disconnect from` [`dip192.lsn.bf1.yahoo.com`](https://dip192.lsn.bf1.yahoo.com)`[ `[`67.195.177.201`](https://67.195.177.201)`] commands=0/0` `Nov 29 11:20:06 mail postfix/submissions/smtpd[2523]: connect from` [ `dip220.lsn.bf1.yahoo.com`](https://dip220.lsn.bf1.yahoo.com)`[`[`67.1 95.177.229`](https://67.195.177.229)`]` `Nov 29 11:20:06 mail postfix/submissions/smtpd[2523]: SSL_accept error from` [`dip220.lsn.bf1.yahoo.com`](https://dip220.lsn.bf1.yahoo. com)`[`[`67.195.177.229`](https://67.195.177.229)`]: -1` `Nov 29 11:20:06 mail postfix/submissions/smtpd[2523]: warning: TLS library problem: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher:../ssl/statem/statem_srvr.c:2283:` `Nov 29 11:20:06 mail postfix/submissions/smtpd[2523]: lost connection after CONNECT from` [`dip220.lsn.bf1.yahoo.com`](https://dip220.lsn.bf 1.yahoo.com)`[`[`67.195.177.229`](https://67.195.177.229)`]` `Nov 29 11:20:06 mail postfix/submissions/smtpd[2523]: disconnect from` [`dip220.lsn.bf1.yahoo.com`](https://dip220.lsn.bf1.yahoo.com)`[ `[`67.195.177.229`](https://67.195.177.229)`] commands=0/0` ​ on my phone ​ https://preview.redd.it/2gdg09hpx73c1.jpg?width=1011&format=pjpg&auto= webp&s=a929c0df17ae4e96489790f28f82fce3d5725e96 I've try both TLS/SSL and STARTTLS ports (143,993, 465, 587) without success, all ports are opened on my firewall. ​ Notes: I can add my mailbox to Gmail app on my Android phone without problem. I consolidate all my mailboxes on Gmail app and use it to check/compose mails on my mobile phone; but Gmail webmail won't accept non-Gmail accounts. So managing my mails in one place: Yahoo webmail for desktop and Gmail app for mobile. ---------------------------------------------------------------------- europacafe · 2023-12-05 10:27 bump it up.
