Issue with group e-mail and campain and mass emails

[ThomasB]

Ok, to summarize all issues:

1. Do not use letters like @ in the "From Name" field.

2. In the Mass Emails dialog, where you specify the SMTP Account, the field is no longer visible if you reload or reenter the dialog.

3. If you specify a "Reply-to-Name" in the Mass Emails dialog and use a group account, then the emails do not contain the name but only the Reply-to-Address.

4. If you setup a group account with a "Reply To Address" in the Administration-> Group Email Accounts settings, and use in the Mass Emails dialog also a different Reply-To-Name,
then the emails you send will have two reply address. One with the "replay-to-name" and the email address from the group emails settings and one email with just the email adress from the Mass Emails dialog.
If you remove the reply-to-name from the group email account, you will have only one email address but without name. See issue 3.

Ok, one issue I have identified.

The problem with =?UTF-8?Q?newsletter@ in the from address happens when you enter the email adress as "From Name". The @ letter is causing this.

From Address	From Name	Result
newsletter@company.com	newsletter@company.com	=?UTF-8?Q? issue
newsletter@company.com	newsletter company.com	works fine

If I check the raw code with thunderbird, it see,s the subject of the html email also prints =?UTF-8?Q? at the start of subject and from address.

Precedence: =?UTF-8?Q?bulk?=

Just found out there was an existing issue: https://github.com/espocrm/espocrm/issues/2923

But still happens with the latest version.

Might be related? https://github.com/laminas/laminas-mail/issues/265 and https://github.com/laminas/laminas-mail/pull/235


If the library is to blame not sure if another one could be used like: https://github.com/PHPMailer/PHPMailer

Not sure about licence and other potential drawbacks.

Now I checked the email with outlook.

[CODE]EspoCrm 8.4.2

I trying to setup an Email/newsletter campaign and ran into a strange issue.

I have system email smtp and two group smtp accounts.

I go to campaign and create my campaign.

I create a mass email with the second group account as sender. The sender address is newsletter@ and the reply adress is person.x@

If I reload the page or to another page and go back the mass email details, the entry for smtp account is empty.

If I send a test email, it seems the correct group account is used.

However my second issue is that I have now two reply addresses in my mail: Person X <newsletter@> and person.x@

I fixed the second issue with two adresse by removing the reply-to adress from the group email account but I see only the email adress and not the name as reply.

Only "person.x@company.com" instead of "Person X <person.x@company.com>"

Email client thunderbird.


Now I checked the email with the outlook client:

The from address reads "=?UTF-8?Q?newsletter@ <company.com?=newsletter@company.com>"
