Hi, the mailserver i’m using only supports authentication through CRAM-MD5, and from its logs I see that discourse tries to authenticating using SASL PLAIN nevertheless, and obviously not succedding. Is there a way to set up discourse to authenticate with CRAM-MD5? ```plaintext 220 foobar.net ESMTP Postfix (Debian/GNU) EHLO barfoo 250-foobar.net 250-PIPELINING 250-SIZE 250-VRFY 250-ETRN 250-AUTH CRAM-MD5 250-AUTH=CRAM-MD5 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN ``` ```plaintext Jul 18 05:21:40 foobar postfix/smtpd[32209]: connect from unknown[82.195.73.13] Jul 18 05:21:40 foobar postfix/smtpd[32209]: Anonymous TLS connection established from unknown[82.195.x.y]: TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Jul 18 05:21:40 foobar postfix/smtpd[32209]: warning: unknown[82.195.x.y]: SASL PLAIN authentication failed: Invalid authentication mechanism Jul 18 05:21:40 foobar postfix/smtpd[32209]: lost connection after AUTH from unknown[82.195.x.y] Jul 18 05:21:40 foobar postfix/smtpd[32209]: disconnect from unknown[82.195.x.y] ``` --- _[View the full topic](https://meta.discourse.org/t/cram-md5-authentication-for-mail/47442)._
