I googled sympatico email settings because I had questions concerning the same host names for both incoming and outgoing mail. Also, wanted to know which ports. Does this look familiar? I can't test it because I don't us sympatico.
http://internet.bell.ca/index.cfm?method=content.view&content_id=1067The following information is from the link above.
Incoming mail server (POP)
POP Server: pophm.sympatico.ca
Port: 995
User name: Email address (e.g: jsmith@sympatico.ca or jsmith@bell.net) and password (e.g.: a123456z)
SSL: Be sure to select the “this server requires a secure connection (SSL)” or “use SSL (Secure Sockets Layers)” option
Outgoing mail server (SMTP)
SMTP Server: smtphm.sympatico.ca
Port: 25 (or 587 if port 25 does not work
Authentication: Yes User name: Email address (e.g: jsmith@sympatico.ca or jsmith@bell.net) and password (e.g.: a123456z)
TLS/SSL Required: Yes (select TLS if available, if not, select SSL)
Under smtp in avast ssl accounts use port 587 (not 25). The above also states to use TLS if available. It seems there are problems with using port 25. Type in the host names as shown above for pop and smtp. Leave your email client (Windows Live Mail) exactly as you have it.http://www.asknardo.com/how-to-solve-outgoing-sympatico-email-problems-using-ssl.phpMainly read this in the article (see below). It is dated January 2010 so take if for what it is worth. Don't know if it relates to newer versions of Avast.
"There are incredibly few ISPs on the planet that are stupid enough to implement SSL security using port 25 for SMTP as Sympatico has done – I can think of only a couple of others that are doing the same thing … one is in Portugal. It is a de facto standard of email worldwide that port 25 is used for unsecured email connections. The de facto email standard for sending SMTP with SSL is port 465.
avast, quite reasonably, assumes that it can scan port 25 connections because the standard is that port 25 connections are unsecured. If there is a requirement from the email server (as there is with Sympatico) that port 25 be secured then avast will, unfortunately, get in the way and prevent the connection. If you happen to be a Sympatico user you have no choice but to turn off outbound scanning."
