hello. I have a problem(again). how do I find one last email from 1 sender in POP3? I didn't find anything in the documentation on this topic(maybe just didn't notice, I'm like that). thanks for your help
POP3 protocol doesn't support searching.
Please note this is not a limitation of Mail.dll client, but of the protocol itself.
Consider using IMAP client: https://www.limilabs.com/blog/pop3-vs-imap
