Mail loop with last X mails

[marcolobaido]

Hi, I need to do a mail loop downloading mail with a specific word in the subject.
I made a task that works perfectly but it's too slow because it analyzes ALL the mails.

I tried to use a "while loop" and "imap folder info" but it's slow too because I must download every single mail to get the subject differently to the "imap mail loop" action.

Is there a way to analyze only the last 100 mails with imap mail loop?

You have to use some counter in the mail loop.
Process messages from 1 to 100. Next you can break the loop. Use Break action

Algorithm will be similar to this:

Code: Select all

IMAP open
IMAP Mail Loop // set ordering number to NUM
   .....
   do something
   .....
   if {num} >100 then
      break
   end if
End loop

[Oleg]

So, if mail box contains less than 100 massages you process all messages. If more than 100 you process only 100 newest messages.

Thanks for you very fast answer,
I have 2178 mails and I need to process messages from 2078 to 2178.

I set the ordering number with the value (num = 2078) breaking when num>100 but it start always from the oldest mail.

imap open
imap folder info
increment variable (2 variables: total mail {nums} and total -100 {num})
imap mail loop (ordering number {num})
if {num}>100
break
if subject contain word
download message
end if
end loop.

What's wrong?

[Oleg]

I'm sorry, you are correct: newest messages are at the end of the list
look at my example below how to read only 100 last messages

Code: Select all

Save the text of the task to a file and use menu Task->Import to import the task into RoboTask.

You can change the amount of the messages, look at the step #4

[marcolobaido]

ok, It works. Thank you very much.
P.s.
I noticed that simple loop is slower than mail loop, this is my impression (can you confirm that?).
However I think that would be useful to add a Mail loop action where I can choose to start from the newest or last mail.

[Oleg]

This task downloads the whole message, but Email loop reads only message headers if it's necessary.
Therefore you see that simple loop works a bit slower.

Maybe we will improve email loop actions (IMAP and POP3) in order to avoid such complex construction
I wrote the request into our ToDo.
