All was fine then suddenly I can only send but not receive e-mails!
A few
(very few) e-mails have come through but senders have also called me
to tell
me that e-mails sent to my account were being bounced back to the
sender.
Help! Please!
Well, then why didn't those that were complaining about the
bounce-backs also tell you what those bounce-backs told them? There
are LOTS of reasons for getting NDRs (non-delivery reports) when
sending mails. Could be the e-mail address was wrong. The domain was
right but the username was wrong so the receiving mail server bounces
back a mail saying that no such account exists (this should actually
be performed during the mail session between sending and receiving
mail servers but can't if the receiver is forwarding mails to
somewhere else). Could be the recipient's mailbox is full; i.e., the
recipient has been very sloppy and never bothered to clean out their
Inbox so they have consumed all the disk space quota for their e-mail
account. Could be the recipient's mail server is down so it is
unreachable. Could be recipient's mail server is too busy and refuses
to accept any more connections, and remains too busy for so long that
eventually the sending mail server gives up and returns a local NDR
back to the sender saying that it couldn't deliver the sender's mail.
Could be your mail provider is using a blacklist and rejects any mails
from those senders. Could be some other reason but you never said
what the bounce-back mails actually reported to the sender.
