Indeed, watching strace for longer shows that (I was always impatient
before):

recvfrom(5, "\366\310\201\202\0\1\0\0\0\0\0\0\5rotor\0\0\1\0\1", 2048, 0, 
{sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.96")}, 
[28->16]) = 23
poll([{fd=5, events=POLLIN}], 1, 4996)  = 0 (Timeout)

I remember now that we have been having DNS hiccups here and that would
seem to be another symptom of that problem. Thanks for the workaround.
I'll ping our sysadmins again :) .

Mutt performs a DNS lookup using gethostname() and getaddrinfo() to try
to find out the host's FQDN.  If you are hanging, it could be this is
not configured correctly.

Adding a line to /etc/hosts with a FQDN may help:
  127.0.1.1  rotor.yourdomain rotor

See also https://muttmua.gitlab.io/mutt/manual-dev.html#hostname
although setting that does not change the startup behavior because the
muttrc is processed afterwards.

Can you start mutt with "mutt -d 2" and see if you get more information 
then? 

Check first that your mutt is compiled with DEBUG though:

mutt -v | grep DEBUG
