(solved) invalid response: * 1 FETCH (UID 389286 FLAGS (\Seen) BODY[] NIL

[gfim]

G'day all,

Just started using fdm 2.2 on FreeBSD 14.3. It's working correctly except for an occasional couple of failures.

[<account>](mailto:<myAddress>): invalid response: * 1 FETCH (UID 389286 FLAGS (\Seen) BODY[] NIL)
[<account>](mailto:<myAddress>): fetching error. aborted

or

[<account>](mailto:<myAddress>): connection closed
[<account>](mailto:<myAddress>): fetching error. aborted

where <account> is one of the account names from my .fdm.conf and <myAddress> is my email address. It can be on any
of a number of accounts. These accounts work correctly most of the time - just an occasional failure. After a failure, it
works correctly on the next run of fdm.

I'm using IMAPS to retrieve email from the server which resolves to mx1.mailchannels.net.

The relevant line from .fdm.conf is:

account "<account>" imaps server "<server>" user "<user>" pass "<password>"

with <account>, <server>, <user>, <password> replaced by the relevant values.

Doing a DNS lookup on <server> gives:

# host -t MX <server>
<server> mail is handled by 0 mx1.mailchannels.net.
<server> mail is handled by 0 mx2.mailchannels.net.

Does anybody have any clues, please?

Thanks in advance,
  Graham

I solved (part of) my own problem. This is a test environment, and I'm using the -k option to fdm to keep the emails on the IMAP server rather than deleting them. On another system, I'm downloading the emails with fetchmail and deleting them from the server. The "invalid response" error occurs when fetchmail deletes an email from the server while fdm is running. It sees that the email is on the server initially, but it's disappeared by the time it goes to retrieve it. When I switch this over to production (get rid of fetchmail and the -k option), the problem will (presumably) go away.

Still not sure about the "connection closed" error though.
