Slow SMTP response from mail.telus.netFor the last 3 days I've been experiencing very slow response to outgoing SMTP service requests. I use mail.telus.net as my outgoing SMTP server (also known as smtp.telus.net).
I called first level support and was told that other people are not experiencing this. I decided to do some investigation on my own and fired up Wireshark to trace the conversation with the mail server. What I see is that the TCP connection setup works as expected (the usual SYN, SYN, ACK), but the first actual SMTP response from priv-edmwaa06.telusplanet.net (which is a response code 220) takes 60 seconds. After that, the transaction proceeds at normal speeds.
Is anyone else seeing this? |

Me too since yesterday afternoon. Can't send at all. |

Same here. I called and complained (after the usual runaround "No, no technical problems reported here. Have you checked your email program? Your anti-virus software?..."
It's not like we have any choice. Telus forces us to use their SMTP server by blocking port 25 for any other SMTP server, so it seems to me that they should have an obligation to their customers to keep theirs working properly.
It's normally not a big deal - the Telus mail servers have always been slow compared to everyone else - but I wasted an hour investigating why my home security system is no longer emailing alerts, only to discover that the Telus SMTP server is exceeding its built-in timeout limits. |

That isn't quite correct. You can access any SMTP server you want - you just can't host it. |

On a Telus internet connection you cannot send SMTP email via port 25 to any SMTP server except smtp.telus.net.
There are some ways to work around it: - If your alternative SMTP server supports alternative port numbers other than the standard port 25, you are allowed to send SMTP email via that port. For example if your computer/internet device supports SSL, you can send email via port 465 to Gmail's SMTP server. - Apparently Telus business internet customers can request port 25 to be unblocked, but they won't do it for personal accounts - You can use IMAP instead of SMTP. Telus does have an IMAP email server, although it's not well publicized.
Unfortunately none of those solutions work for my home security system - its firmware supports only standard port 25 SMTP email with a 30-second timeout. |

SMTP is a protocol used to SEND email. IMAP is an alternative to POP3. SMTP is used with both IMAP and POP3 to send mail. |

Thanks for that clarification. Ok, IMAP not an alternative to SMTP (that was actually a suggestion of the Telus tier-2 tech support - I didn't bother to investigate further). |

I cringe at the thought of trying to setup IMAP with Telus. It's difficult enough trying to get support for SMTP. |

Actually setting up IMAP is easy and also pretty nice if you have a few computers in the house.
Getting support for it is also quite good. |

Reset your gateway by turning it off for 15 seconds and then restarting. Mine was hooped today again, before the reset I was at half speed, now I'm back to full speed. A glitch existed here some where, what it is I have no idea. The DNS grabbing has some sort of problem. Current test shows: |

Different issue. When we say that the SMTP server is slow, we mean that it takes more than 30 seconds to respond to the initial inquiry from the email program, whereas other requests such as reading web pages and POP mail are still responding quickly and transferring data quickly. It's a specific server issue, not an overall connection issue that can be fixed by resetting the modem. |

Have you tried a different smtp server? priv-edmwaa06.telusplanet.net is timing out for me as it looks like it's going to a local address of 192.168.81.206 which is sort of goofy... but there's nothing stopping you from using a different one.
Try mail.telus.net instead of smtp.telus.net. It should reference a different server completely. You can actually also use pop.telus.net as your smtp server if you make sure you're still connecting to port 25. |

no change with mail or smtp and pop.telus.net fails on send. |

Try SMTP (port 25) using IPs: 204.209.205.51 204.209.205.52 204.209.205.53 199.185.220.245 199.185.220.249
If the 204.* IPs are slow to respond, try the 199.* ones. They take different routing so hopefully one will work better than the other. If they both suck, I'm out of suggestions.

Same response for me on all of them. The 204's were maybe 10 seconds or so faster than the 199's if there was any difference. |
