How to delete a single email

[GuppyHJD]

I am working through the Read_Single_eMail example and have it working on an ESP8266 NodeMCU board. I then tried to delete the email after reading it. I looked at the Delete Messages example but it is showing deleting 10 messages. It seems like after I have read an email, I have the UID and should be able to do a delete.
Is there a list of commands available in the Client?

You have to search the messages with keywords in the mailbox to get UID of the search result messages.

Or you have to know the message index in the mailbox and use getUID from index which index begins with 1 to total messages in the mailbox.

In the example below, the message count is an index to get the UID of latest message for reading (fetch).

ESP-Mail-Client/examples/IMAP/Read_Single_Email/Read_Single_Email.ino

Lines 220 to 223 in e41877c

	/** Message UID to fetch or read e.g. 100.
	* In this case we will get the UID from the max message number (lastest message)
	*/
	config.fetch.uid = imap.getUID(imap.selectedFolder().msgCount());

It does not mean reading message to get UID.

From search example, you have to set the search criteria which composed from many keywords.

ESP-Mail-Client/examples/IMAP/Search_Emails/Search_Emails.ino

Lines 256 to 257 in e41877c

	/* Config to search all messages in the opened mailboax (Search mode) */
	config.search.criteria = F("UID SEARCH ALL"); // or "UID SEARCH NEW" for recent received messages
