I.e. mail for xhghj...@isbd.net will arrive in the catchall mailbox. So I just search the To: address for anything that might be a typo for one of our names or anything else that might be of interest. I have an associated configuration file that specifies the patterns to look for so I can change things on the fly as it were.
One of the scripts that I'm having trouble converting to Python 3 is the one that does this catchall management. > >> >E.g. in this case the only (well the only ready made) way to get a > >> >POP3 message is using poplib and this just gives you a list of lines > >> >made up of "bytes as text" :- > >> > > >> > popmsg = pop3.retr(i+1) > >> > >> Ok, so you have bytes?
