Hello, I've recently installed msmtp 1.4.31 and offlineimap to use mu4e in Emacs as an interface to my personal email. Using these applications has worked well for me and I have no problems downloading my personal Gmail account using offlineimap and sending using msmtp. I like the searching capabilities of mu4e so much that I'd like to do the same for my work email, an Exchange account but one that offers IMAP services to end users. While I have been successsful downloading my work email, I have not yet been able to send email with this account using msmtp. I'd appreciate troubleshooting advice from the list.
#msmtp configuration: My configuration for msmtp, pasted below, is stored in ~/.msmtprc and has worked for my personal account (listed in the configuration as "Gmail") and, it appears to be at least partially successful in communicating with my work email server (account "Work"). The current settings for my Exchange-based work account are identical to those I use to successfully send email via smtp on Thunderbird on the same machine running Xubuntu 14.04. ---begin quote--- # Accounts will inherit settings from this section defaults auth on tls on tls_starttls on tls_trust_file /etc/ssl/certs/ca-certificates.crt logfile ~/.msmtp.log # gmail account Gmail host smtp.gmail.com port 587 from usern...@gmail.com user usern...@gmail.com passwordeval "gpg -q --for-your-eyes-only --no-tty -d ~/.gmailmailpass.gpg" tls_trust_file /etc/ssl/certs/ca-certificates.crt # work email account Work host EMAIL.WORK.COM auth ntlm domain WORK.COM ntlmdomain WORKDOMAIN port 587 from firstname.lastn...@work.com user USERNAME passwordeval "gpg -q --for-your-eyes-only --no-tty -d ~/.workmailpass.gpg" tls_trust_file /etc/ssl/certs/ca-certificates.crt # Set a default account account default : Work ---end quote--- #testing msmtp: In order to easily test my msmtp configuration from the command line, I took some advice from the ArchWiki (see "testing msmtp" https://wiki.archlinux.org/index.php/Msmtp#Test_msmtp), created a simple text file per the instructions ("test.email"), and tried out different ports, authentication schemes, and username/domain formats. The example session below uses the current settings, the same ones that run successfully under Thunderbird on the same machine (although msmtp exposes many more options than the Thunderbird interface). ---begin quote--- will@willxubook:~$ cat test.email | msmtp -debug -a default usern...@work.com ignoring system configuration file /etc/msmtprc: No such file or directory loaded user configuration file /home/will/.msmtprc using account default from /home/will/.msmtprc host = EMAIL.WORK.COM port = 587 timeout = off protocol = smtp domain = WORK.COM auth = NTLM user = USERNAME password = * passwordeval = gpg -q --for-your-eyes-only --no-tty -d ~/.workmailpass.gpg ntlmdomain = WORKDOMAIN tls = on tls_starttls = on tls_trust_file = /etc/ssl/certs/ca-certificates.crt tls_crl_file = (not set) tls_fingerprint = (not set) tls_key_file = (not set) tls_cert_file = (not set) tls_certcheck = on tls_force_sslv3 = off tls_min_dh_prime_bits = (not set) tls_priorities = (not set) auto_from = off maildomain = (not set) from = usern...@work.com dsn_notify = (not set) dsn_return = (not set) keepbcc = off logfile = /home/will/.msmtp.log syslog = (not set) aliases = (not set) reading recipients from the command line <-- 220 work.com Microsoft ESMTP MAIL Service ready at Thu, 7 Aug 2014 06:57:47 -0500 --> EHLO WORK.COM <-- 250-EMAIL.WORK.COM Hello [50.201.41.253] <-- 250-SIZE 31457280 <-- 250-PIPELINING <-- 250-DSN <-- 250-ENHANCEDSTATUSCODES <-- 250-STARTTLS <-- 250-AUTH GSSAPI NTLM <-- 250-8BITMIME <-- 250-BINARYMIME <-- 250 CHUNKING --> STARTTLS <-- 220 2.0.0 SMTP server ready TLS certificate information: Owner: Common Name: WORK.COM Organization: SOME UNIVERSITY Organizational unit: SOME SCHOOL Issuer: Common Name: InCommon Server CA Organization: Internet2 Organizational unit: InCommon Country: US Validity: Activation time: Sun 08 Jan 2012 06:00:00 PM CST Expiration time: Thu 08 Jan 2015 05:59:59 PM CST Fingerprints: SHA1: 6A:72:52:C9:29:83:2D:72:DA:92:40:9B:BE:6B:11:58:8A:B5:5B:B9 MD5: 85:E4:9D:4C:9A:A7:E1:DC:42:D6:B7:C6:F0:68:E3:BE --> EHLO WORK.COM <-- 250-WORK.COM Hello [50.201.41.253] <-- 250-SIZE 31457280 <-- 250-PIPELINING <-- 250-DSN <-- 250-ENHANCEDSTATUSCODES <-- 250-AUTH GSSAPI NTLM <-- 250-8BITMIME <-- 250-BINARYMIME <-- 250 CHUNKING --> AUTH NTLM <-- 334 NTLM supported --> TlRMTVNTUAABAAAAB7IAAAcABwAgAAAACQAJACcAAAB3bW9ucm8xbGF3Y2VudGVy <-- 334 TlRMTVNTUAACAAAAEgASADgAAAAFgoECfq4e9WBM+iwAAAAAAAAAAI4AjgBKAAAABgGxHQAAAA9MAEEAVwBDAEUATgBUAEUAUgACABIATABBAFcAQwBFAE4AVABFAFIAAQAKAEUATQBBAEkATAAEABYAbABhAHcALgBsAHMAdQAuAGUAZAB1AAMAIgBlAG0AYQBpAGwALgBsAGEAdwAuAGwAcwB1AC4AZQBkAHUABQAWAGwAYQB3AC4AbABzAHUALgBlAGQAdQAHAAgAhUAlzzayzwEAAAAA --> TlRMTVNTUAADAAAAGAAYAG4AAAAYABgAhgAAABIAEgBAAAAADgAOAFIAAAAOAA4AYAAAAAAAAACeAAAABYKBAkwAQQBXAEMARQBOAFQARQBSAHcAbQBvAG4AcgBvADEAdwBtAG8AbgByAG8AMQClUy0rlHmraG5K7C2HG0DT+mvt0sWQbQUK1rTh5bV3oIy1YhlIwgx9J20XgAHfsEI= <-- 235 2.7.0 Authentication successful --> MAIL FROM:<usern...@work.com> --> RCPT TO:<usern...@work.com> --> DATA <-- 250 2.1.0 Sender OK <-- 250 2.1.5 Recipient OK <-- 354 Start mail input; end with <CRLF>.<CRLF> --> To: usern...@gmail.com --> From: --> Subject: A test --> --> Yadda, yadda, yadda. --> . <-- 550 5.7.1 Client does not have permissions to send as this sender msmtp: the server did not accept the mail msmtp: server message: 550 5.7.1 Client does not have permissions to send as this sender msmtp: could not send mail (account default from /home/will/.msmtprc) will@willxubook:~$ ---end quote--- I know very little about email and smtp except what I've been able to learn as I've researched this problem.

This can be the result of per-host or per-recipient filtering. This memo does not discuss the merits of any such filtering, but provides a mechanism to report such. This is useful only as a permanent error." http://www.iana.org/assignments/smtp-enhanced-status-codes/smtp-enhanced-status-codes.xhtml Knowing very little about smtp error codes, I've asked our email server administrator about this. He suggested that I try prepending the domain to my username (e.g., DOMAIN\USERNAME) but that hasn't worked. I know little about this but it appears that the problem is bound up in why, after the successful authentications and everything seeming to be correct with starttls, that the third authentication fails. I'd be grateful for guidance on the right questions to ask (and how to ask them)!
