msmtp/mutt trouble sending mail (server message: 451 4.4.1)

Hello,

I was using msmtp as mta with mutt for some time now but all of a sudden msmtp doesn't work with _one_ of the two mail servers anymore. (The other one being gmail.)

Sending mail from my main account results in the following obscure message:

Code:

msmtp: the server did not accept the mail
msmtp: server message: 451 4.4.1 timeout waiting for input during message collect
msmtp: could not send mail (account my_account from /home/me/.msmtprc)

I didn't alter anything neither in .muttrc nor .msmtprc, could this, thus, be some change on the server side? My other account works just fine and no software was updated in between. The machine is running arch linux with most recent packages. Thanks for any help or suggestions,

Philipp

The relevant part of .msmtprc:

Code:

account my_account
host    smtp.the.server
from    me@the.server
port    587
tls     on
tls_trust_file  /etc/ssl/certs/ca-certificates.crt
tls_min_dh_prime_bits 512
auth    plain
user    me
password my_pass

The only thing I can suggest is testing to make sure it works outside of msmtp. Do it manually using the openssl tools.
