==About==
As of July 2010, the situation was like this. (In our area, Verizon's wired accounts are being taken over by [[Frontier Communications]] as of 2010-07-28, so I won't be able to personally verify any changes to Verizon's technical configuration. --[[User:Woozle|Woozle]] 21:28, 28 July 2010 (UTC))
==The Good==
* Verizon does not block port 110, necessary for retrieving email from a remote [[POP3]] server or for hosting one's own POP3 server. (...though I think they did at one point.)
* Verizon does not block ports 143 or 993, necessary for retrieving email from a remote [[IMAP]] server or for hosting one's own IMAP server.
==The Bad==
* Verizon blocks port 25, which is necessary for [[SMTP]] (outgoing email).
** This means that if Verizon is your [[internet service provider|ISP]], you have to use Verizon's SMTP servers to send email.
* Verizon's servers block outgoing email whose return address is not a [[domain name|domain]] owned or hosted by them...
* ...unless the sender authenticates using an existing Verizon user/password.
** Fortunately, most [[email client|client]]s can do this now.
** Unfortunately, they don't make it easy to discover the authentication work-around; at least [http://www.verizon.net/central/vzc.portal?_nfpb=true&_pageLabel=vzc_help_contentDisplay&objId=44427 one] of their applicable help pages implies that there is no work-around.
==The Ugly==
As of 2010-07-28, as customer accounts were being "transferred" over to Frontier's servers, Verizon's SMTP server (incoming.verizon.net) stopped recognizing my consulting client's login credentials, while Frontier's SMTP server (smtp.frontier.com) was not yet responding to hails. My client was therefore unable to send email from their office network, and had to resort to using their mobile devices (2 Blackberrys and an [[iPhone]]) or calling customers on the phone. --[[User:Woozle|Woozle]] 21:28, 28 July 2010 (UTC)
