slow outgoing email

Friends--

 

For the last 2 months or so, outgoing email using comcast has been extremely slow.

 

About 2/3 of the emails I send, take 30 to 60 seconds to actually send. The other 1/3 go out almost instantly, like before. I remember having a similar problem maybe 5 years ago, and after I posted here, and someone from Comcast interacted with me, the problem was fixed. For years. Till now.

 

I am using Thunderbird 68.7.0 (64 bit) on 18.04 Ubuntu. Settings: smtp.comcast.net port 587, starttls.

 

(BTW, I tried searching the forums and found several likely threads for answers (latest was 2019), but I could find no way to actually read the threads. I clicked all sorts of things, and everything seemed to go to a page "What can we help you with?" Got any hints on how to use the search?)

doing a quick google search of the issue shows that its a pretty common problem and this shows something to try out: https://protonmail.com/support/knowledge-base/thunderbird-connection-server-timed-error/ (in the example shown in the support link, you will want to search for comcast.net instead of mailnews.tcptimeout). Overall it appears to be an issue either with the email client (Outlook, Thunderbird, MacMail, etc.) or with the device. When its the device looks like the most common one is a firewall or anti-virus program preventing/slowing down the email client. 

 

Unfortunately email clients are third party to Comcast and are simply a recovery or relay tool for interfacing with our server(s). The support articles and guidance we would be able to provide for troubleshooting issues regarding third party email clients or your personal devices is limited/non-existent as its not our product/offering.

@dgermann I am having the same problem and have been for approximately the same time period.  Outgoing mail just hangs.  About 95% of the time, if I cancel it and hit "send" again, it sends immediately; other times it might take several tries.  This happens on both of my computers.  I haven't been able to find anything other than the message I am replying to that mentions this problem.

I've been having the same problem as well.  Even just trying to mark a bunch of emails for deletion it will pause for up to 30 seconds until I can select more.  This may happen several times when selecting numerous messages.  Seems like their servers just stop communicating.  I've tried this on three computers, and with Edge, IE, Chrome and Firefox and have tried it with my sisters and my brother in law's email and all of them respond the same.  I have the same issue when using email from my iPhone.   I have the same results when trying it from my work Internet with gigabit speed.  It's happening on too many systems to be a user configuration issue, it has to be something with Xfinity's system.

Glad to know its not just me. When I send a message no matter how short or long it is...it seems to take forever to be 'sent'. Doesn't Comcast have anyone minding the server functionality? It should be sent immediately. I have also had the issue with 'delete' function...it just sits there. I know with high speed everything we are spoiled but my goodness...why is no one addressing this from Comcast especially here on the forums. Its like we are talking into air. Used to be that Comcast employee reps were on these forums and could offer something  when we voice problems but its been 'crickets' on many subjects the last few months.

@dgermann can you please click my name and "send message" me the UID you are having this issue with? If its the same one you are using for the forums - you haven't sent out any emails from comcast.net in the last 30 days. You will want to check your email client settings if it is.

@Kathleen10 @dewo @TerriB The server shows all of your emails being sent the second the request gets sent. This means there might be a delay in what you use to send the email to when it hits our server telling it to send. Can you each please clarify what you are using to send email, if you use VPN, and what the exact error if any you receive.

@ComcastCSAEmail When on my desktop I normally use Outlook 2016 to send/download mail and yes its configured correctly and have not made any changes and am the only one who uses the desktop. The only time I go to Comcast webmail is when Outlook syncs my folder endlessly but this was not the case with the slow server response.  On my phone and tablet I use Xfinity Connect. The experiences with the slow server were on my desktop and it seems ok now but it went on for a couple of weeks.

FYI....can't 'quote' your response....what happened to the 'quote' icon? We used to have a 'quote' option and then Comcast changed it and put the quote marks at the end of the icon list after spellcheck and now its not there either.  How do we 'quote' now? Quoting makes the forums easier to follow as it connects posts together.  Please don't tell me we have to copy and paste now?

You think?  🙂   But it looks like it may be a T'bird problem.  I don't have this problem with my other emails.

I'm using Thunderbird.  Initially I would get a message saying it had timed out - after hanging for a long time.     I don't let it hang that long anymore.  If it doesn't send immediately,  I cancel it and send again - it usuall sends right away on the second try.  That may be what you're seeing - the second try.

Kathleen....You should not have to send it twice to get it to work.

Thunderbird 68.10.0

MacOS 10.15.6

 

Problems with pop3 and smtp servers comcast.net started this weekend.

I can get mail intermittantly. When it doesn't work this is displayed on the bottom of the main window:

"Host contacted, sending login information"

Then the Tools->Developer Tools->Error Console prints this when it fails:

NS_ERROR_NOT_AVAILABLE: Cannot call openModalWindow on a hidden window Prompter.jsm:441

 

Sending mail continually fails.

 

But, then it works. But then it fails!

We were just told by the Comcast employee helping us on this issue that its not Comcast's server causing the problem.........its either our device or the third party we use for email. I still say its their server but  I think we have lost this argument.

Ok, I repeadedly shur down my comcast sb621 modem and my apple airport extreme (because rebooting only once never fixes anything). It is all working now.

I can send and receive thunderbird emails using wired and wireless connections.

But, I really don't trust that it is working because of the reboots.
