The "username" part of an e-mail address is case insensitive and generally with Linux and UNIX, usernames are almost always all lower case. But sometimes non-UNIX users sign up to mailing lists and capitialize their E-Mail address, since usually the E-Mail address is starting with their name and they routinely capitialize their name. A Linux / UNIX is used to usernames being all lower case and so think of E-Mail addresses as being all lower case. The -i option is a usefull option to use with grep, even when it might be redundent. > > Turns out what's really happening is that all mail from this list is > going into this user's junk folder.

Ranging from considering all such mail spam to pre-filing them as newletters or something. Many inexperienced users of these services have no idea that this is happening and often have no clue how to find out where their mail has gone, any will complain to the list admin that they are not getting any messages from the list. > > > Thanks, > > > Jayson > > > ------------------------------------------------------ > Mailman-Users mailing list -- mailman-users@python.org > To unsubscribe send an email to mailman-users-le...@python.org > https://mail.python.org/mailman3/lists/mailman-users.python.org/ > Mailman FAQ: http://wiki.list.org/x/AgA3 > Security Policy: http://wiki.list.org/x/QIA9 > Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ > https://mail.python.org/archives/list/mailman-users@python.org/ > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services
