Does RR offer SMTP authentication to allow legit senders to login before they |
| 11 |
can send messages? They may also require that you use a different port when |
| 12 |
you are trying to connect to their mailserver from an IP address that does |
| 13 |
not belong to them (e.g. port 587, instead of the vanilla SMTP port 25). |

I know that some US ISPs are blocking port 25 just for this reason (there's |
| 19 |
many pwned machines spewing spam out there) even from IP addresses that |
| 20 |
belong to them. Some, like comcast, will only block port 25 if they see |
| 21 |
unreasonably high traffic over short periods of time. Others block it right |
| 22 |
from the word go. |

I think that this is what ISPs want, to control the flow of emails and so |
| 28 |
hopefully minimise spam from their block of IP addresses. If your father has |
| 29 |
a Verizon account then you should be able to set your SMART_HOST and |
| 30 |
appropriate port to send (relay) emails via Verizon's mailservers if you're |
| 31 |
using Sendmail, or configure your father's mail client accordingly. |

I suggest you use POP3 unless your father has reasons (as mentioned above) for |
| 52 |
using IMAP4. The latter is not as efficient (data wise) as POP3, but adds |
| 53 |
functional flexibility and acts as an online mailbox back up, just in case |
| 54 |
your father's PC/disk packs up. |
| 55 |
|
| 56 |
Once you set gmail as you want it and enable POP3/IMAP4 access for him on the |
| 57 |
gmail GUI, their system is essentially maintenance free. It is also more |
| 58 |
likely to outdo your ISP performance in terms of uptime (although there have |
| 59 |
been a couple of instances lately with gmail servers becoming unavailable). |
