I too have been having this problem. But mine does not happen all the time. I would have to say, on the average, I have this problem about once a month. And on any day I have it, it may happen 2 or 3 times during the day. I have 3 email accounts: one through peoplepc and 2 through my current ISP, through 2 different servers. I send and receive through all 3 accounts, though peoplepc is not used as much as the other 2. So, on the average, for 29 days out of the month there is no problem whatsoever. Then all of a sudden, usually for about 10-15 minutes, I cannot send through the 2nd account through my current ISP. The error goes like this:
Sending message (date, time, etc)
Logging into smtpout.secureserver.net server....
Socket error # 0
While this is happening, if there are emails on that server, they will download to me just fine. If I am sending/receiving from the other 2 accounts they are just fine. Courier, which I came to Poco from, also did this, but probably less frequently than Poco.
I have even and gone and logged into the faulting servers webmail portal, with no problem. Once logged in, tried to send to no avail. Just glad it doesn't last that long.
Course, ISP, automatically says it is fault of my email program. Why then has it done it with 2 completely different programs? Strange!
I run Vista, Firefox 3.5.3, Comodo Security Suite, Spyware Terminator, Threatfire, and WinPatrol. Oh, yes, and MailWasher Pro.
My internet connection is a hybrid - radio/wireless from their tower to my radio/antenna to ethernet to computer. I live in the country and dialup out here was terrible - barely state legal. This is a bit more expensive than what in town broadband would be, but it beats the heck of my old dialup.
Anyway, I have this in through email help. Just thought I would post it here and see if anyone had any thoughts.
Thanks in advance
