apparent 31 character username limit for smtp auth
I'm running into an issue on an OpenSMTPD mail server where the mail client cannot successfully authenticate via SMTP auth on port 587 when the username is longer than 31 characters. Happens with both Mailbird and Thunderbird email clients. These are the errors that show up in the logs when the username is over 31 chars: Mar 12 21:51:17 mx smtpd[26118]: smtp-in: Failed command on session 78fa93cb23366cfe: "AUTH PLAIN (...)" => 501 5.5.2 Syntax error: Syntax error environment: OpenBSD 5.8 release LibreSSL 2.2.6 OpenSMTPD 5.7.3 Mailbird 2.2.5.0 Thunderbird 38.6.0 /etc/mail/smtpd.conf pki domain.tld certificate "/etc/ssl/domain_tld.crt" pki domain.tld key "/etc/ssl/private/domain_tld.key" table creds "/etc/mail/creds" table trusted-relays"/etc/mail/trusted-relays" table enforce-tls "/etc/mail/enforce-tls" table vdoms "/etc/mail/vdoms" table vusers"/etc/mail/vusers" bounce-warn 1d limit mta inet4 listen on lo inet4 listen on lo0 port 10028 tag DKIM_OUT # outgoing mail listen on egress inet4 tls pki domain.tld listen on egress inet4 port 587 tls-require pki domain.tld auth mask-source # tagged mail returned from dkimproxy_out relays out accept tagged DKIM_OUT for domain relay tls # require STARTTLS for domains known to support it, otherwise fail hard accept tagged DKIM_OUT for any relay # incoming mail for local users delivered via maildir accept from any for domain virtual deliver to maildir "/var/maildir/%{dest.domain:lowercase}/%{dest.user:lowercase|strip}/mail/" # relay other email to the Internet at large accept from source for any relay via smtp://127.0.0.1:10027 accept for any relay via smtp://127.0.0.1:10027 -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org
