问题 I'm using pyramid_exclog to log exceptions and send those exceptions as email. I'm using Amazon aws SMTP to send emails. But I'm getting the following error: SMTPAuthenticationError: (530, 'Must issue a STARTTLS command first') Here's the code I use: [handler_email_exc_handler] class = handlers.SMTPHandler args = (('email-smtp.us-east-1.amazonaws.com', 587), 'no-reply@company.com', ['me@company.com'], 'Company Exception' ,('<username>','<user_key>'),None) level = ERROR formatter = exc

问题 I have a ASP.NET web form for sending emails using SMTP. The hosting provider is 1and1. It worked for year. It stopped working several weeks ago. I receive the following error: "The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required" 1and1 support is unable to explain the reason for the change. I would appreciate your help (see the VB.NET code below). I tried to change the port to 465 and 587, as well, I tried to

问题 In the Graph API explorer, you can send an email with the endpoint https://graph.microsoft.com/v1.0/me/sendMail and a basic json payload of "message": { "subject": "Meet for lunch?", "body": { "contentType": "Text", "content": "The new cafeteria is open." }, "toRecipients": [ { "emailAddress": { "address": "user@domain.com" } } ], "from":{ "emailAddress": { "address": "smtp:my_alias@domain.com" } } } When I send this request, it still sends the email as user@domain.com instead of my email

问题 I'm trying to analyze a mail header to figure which element (MUA, MTA...) creates each. My supposition is: The sender MUA composes the body (including Content-Type, Mime, Content-Transfer-Encoding), and sends it via SMTP to the sender border MTA. MUA provides info for the the initial headers (From, To, Reply-To, ) which are inserted by this MTA This MTA inserts MessageID and Return_Path (and all extra headers and X-Headers it desires) Then it starts 'hoping'. On each hop the receiving MTA

问题 I just used the email_verifier gem (https://github.com/kamilc/email_verifier) to check if a list of emails was valid (ie. email account exists on a given server). Unfortunately this has blacklisted my own IP on several servers since it turns out that this gem pretends to send email. Is there a (different) way to verify that an email account exists without getting blacklisted? 来源： https://stackoverflow.com/questions/17685624/verify-emails-accounts-without-getting-black-listed

问题 I'm attempting to send a message through a BizTalk SMTP Send Port. Specifically, I am sending a message through a "specify-later" port of an orchestration. My goal is to attach the message body to the sent email with an attachment filename of my choosing. However, no matter what I try the attachment name remains "body.csv" I have tried: Multipart message with a single part + set MIME.FileName on this part. Multipart message with two parts (both attached) + set MIME.FileName on both parts (the

问题 I'm the owner of a domain, and I'm currently hosting its mail (MX) in Google Apps for Business. I have a catch-all account, so if someone replies an e-mail to generated-unique-id@mydomain.com , I have a robot that will read that e-mail and do some processing. Problem is: How can I send an e-mail from that sender's address? I mean: I cannot create a userid for every generated id, and if I authenticate into Google SMTP with some user, the sender is automatically filled as that user address. (I
