MailMessage.To.Add() throwing exception : “An invalid character was found in the mail header: ‘,’.”

April 6, 2024 by Tarik

Got the culprit: It’s the extra comma(,) at the end of last email address mailMessage.To.Add(“[email protected],[email protected],”); Remove the trailing comma and it will work: mailMessage.To.Add(“[email protected],[email protected]”); If this does not work in SharePoint then please add each address separately onto MailMessage object like below; foreach (var address in StringofEmails.Split(“,”)) { MailMessage.To.Add(new MailAddress(address.Trim(), “”)); }

Mails Sent via SMTP should get reflected in the Sent folder on the Email Server too? [closed]

January 9, 2024 by Tarik

Usually, an e-mail client such as Microsoft Outlook will receive messages via IMAP4 and send messages via SMTP. I am unaware of many mail servers that automatically save mail sent through them via SMTP in the server-based Sent folder besides Gmail/Google Apps. Typically though, once an IMAP4 connection (as opposed to POP3) to the mail … Read more

Mails not being sent to people in CC

January 3, 2024 by Tarik

I think that you will need to put the CCADDR with the TOADDR when sending the mail: s.sendmail(FROMADDR, TOADDR+CCADDR, msg.as_string()) You’re correctly adding the addresses to your message, but you will need the cc addresses on the envelope too. From the docs: Note The from_addr and to_addrs parameters are used to construct the message envelope … Read more

Setting up DomainKeys/DKIM in a PHP-based SMTP client [closed]

The SMTP server requires a secure connection or the client was not authenticated

Try setting the EnableSsl property to true: smtpClient.EnableSsl = true; AFAIK this property can only be set in code and cannot be specified in the config file.

Ruby mailer is coming up with an EOFError

December 27, 2023 by Tarik

This can also happen if the SMTP server is down. (I use a 3rd party mailer called Sendgrid and this happened once when it goes down entirely)

In SMTP, must the RCPT TO: and TO: match?

December 26, 2023 by Tarik

No, they don’t have to match. When the message is sent, the SMTP Server (aka Message Transfer Agent or MTA) is creating a so called SMTP envelope which contains the recipients and the sender of the message (see RFC5321): SMTP transports a mail object. A mail object contains an envelope and content. The SMTP envelope … Read more

Best Practices – Sending javamail mime multipart emails – and gmail

December 23, 2023 by Tarik

Solved! It seems according to the multipart MIME spec, the order of the parts are important. They should be added in order from low fidelity to high fidelity. So it seems GMail follows the spec and uses the last part. In my case I had them HTML, Text. I just swapped the order to Text, … Read more

December 19, 2023 by Tarik

Now it is totally different in Gitlab 5.2+. It is in “/home/git/gitlab/config/initializers/smtp_settings.rb.sample” and we just need to follow the instructions in that.
