[Users] Periodic "connection failed"

[Pierre Fortin]

This is not a response to the original problem; but additional
information that may help understand what is going on...  

This may be a DNS problem...

Actually, you are using this domain as seen in the headers of your
messages to this list:
  Received: from haines by engels.HistoricalMaterialism.info with local

A bit of dig'ing (output redacted -- vs. +short) reveals that all
addresses are in Torrance, CA, except for histmat.net...

Sounds like there's a lot going on there re DNS...  seeing the
contents of your ~/.claws-mail/accountrc for this account (minus the
password[1] lines) might help.

[1]  password=, smtp_password=, 
     in_ssl_client_cert_pass=, out_ssl_client_cert_pass=
