Recently, I suddenly encountered "SASL authentication failed", when trying to send an e-mail using Mutt 2.3.2 on Gentoo Linux ; earlier that day, I had sent several e-mails successfully & had made no changes in my hardware or software. I have used Mutt without serious problems since c 1998 .At the end of .muttrc I have set ssl_starttls=yes set ssl_force_tls=yes set smtp_url="smtp://<me@myispaddress>:25"
Double check the port number. This would typically be :587 when using STARTTLS. 25 is only used between SMTP servers for relaying email nowadays.
